Dorsal Body Cavity Contains the cranial cavity and spinal column
Ventral body Cavity Contains all the structures within the chest and abdomen; diaphragm divides the ventral cavity into the thoracic cavity (superior to the diaphragm); below the diaphragm are the abdominal and pelvic cavities.
Anatomical position A standard position in which the body is facing forward, the feet are parallel to each other, and the arms are at the side with the PALMS facing FORWARD.
Prefixes Metric Kilo 1000 = 10^3
Hecto 100 = 10^2
Deka 10 = 10^1
deci 0.1 = 1/10 = 10^-1
centi 0.01 = 1/100 = 10^-2
milli 0.001 = 1/1000 = 10^-3
Respiratory System Primary function of the LUNGS is: Breathing in oxygen and exhaling carbon dioxide.
1. Air is inhaled through the nose into the TRACHEA, passes into the right and left BRONCHIAL TUBES.
2. Within the bronchial tubes are tiny hairs called CILIA, keep the airway clear by removing unwanted matter from the lungs.
3. After leaving the bronchial tubes, air travels into the ALVEOLI, which are tiny air sacs that are surrounded by capillaries.
4. The alveoli permit the exchange of oxygen and carbon dioxide to occur.
5. The oxygen is then transported by red blood cells into the bloodstream.
6. This process begins when the DIAPHRAGM, an abdominal muscle that contracts, pulls air into the lungs during INSPIRATION (the act of taking in oxygenated air.)
7. When the diaphragm relaxes, carbon dioxide is forced out of the body through EXPIRATION.
CNS --Brain and spinal cord are of the CENTRAL NERVOUS SYSTEM.
-peripheral nervous system (PNS). --Cranial and spinal nerves (extend beyond CNS) make up PERIPHERAL NERVOUS SYSTEM.
--PNS divided into AUTONOMIC NERVOUS SYSTEM and SENSORY-SOMATIC NERVOUS SYSTEM
--AUTONOMIC NERVOUS SYSTEM Controls automatic body functions -heartbeat -digestion
Divisions of ANS SYMPATHETIC NERVES (active when a person is excited or scared) and PARASYMPATHETIC NERVES (which are active when a person is eating or a rest).-These two types of nerves have opposite effects on the body-Helps to maintain a balanced internal environment
SENSORY-SOMATIC NERVOUS SYSTEM Consists of: 12 pairs of cranial nerves; 31 pairs of spinal nerves -controls voluntary actions-talking and walking
GANGLIA collection of nerve cell bodies within the nervous system
DENDRITES receive stimuli from the internal and external environment and bring those stimuli to the neurons
NEURONS specialized cells that make up the nervous system and transmit messages for interpretation.
Axon connects one neuron with another neuron over a fluid filled gap called a SYNAPSE
Synapse Chemical neurotransmitters pass through the synapse to transmit an impulse to another neuron. (transmission happens @ 90 meters per second).
Nervous System Functions 1. To provide sensory functions 2. To provide motor functions 3. To provide integrative functions-All of these functions work together with other body systems to react to STIMULI and maintain homeostatis within the body.
Sensory functions -feeling pain -feeling heat -other stimuli The face, fingers and toes are more sensitive to stimuli because they have a greater number of SENSORY NEURONS than do other parts of the body.
REFLEX -When the body senses pain, it may automatically withdraw from it.
Reflex Action occurs when neurons transmit a message to the spinal cord --sends a message back to the muscles to react before the message is transmitted to the brain.
Motor functions Motor function serves to carry electrical impulses from the CNS to the EFFECTORS
Effectors -most commonly the glands and muscles.
Integrative Function Integrative function uses sensory info to make decision by joining together sensory input with memories already stored within the brain, also uses sensory info to develop thoughts and feelings upon which decisions may be based at a later time.
Digestive system Digestive system is composed of the alimentary canal and accessory structures.-Includes:--mouth--esophagus--stomach--small intestine (duodenum, jejunum, ileum)--Large intestine (colon)--anus
Mechanical churning of the stomach also continues to break the food down into smaller pieces.
Accessory structures -teeth -salivary glands -pancreas -liver -gallbladder
The gastrointestinal tract (stomach and intestines) -long, muscular tube lined with smooth muscle.
PERISTALSIS Rhythmic contraction that propel food towards the colon and anus.---These contractions move food along the gastrointestinal tract as the food is mechanically and chemically broken down.
Digestion (The mechanical and chemical breakdown of foods)
In mouth -teeth grind-chew-tear food into smaller pieces
enzymes Chemicals that break down proteins, carbs and fats into nutrients that can be absorbed through the wall of the intestine into the bloodstream.
Salivary amylase Begins carbohydrate breakdown in the mouth.
Enzymes in stomach An enzyme to begin protein digestion (protease), hydrochloric acid, and intrinsic factor, which increases the stomach's absorption of vitamin B12.
Digestion 2 Fat-laden CHYME (the mixture of food, chemicals, and enzymes in the stomach) remains in the stomach longer than carbohydrate-laden chyme, which advances more quickly into the small-intestine (duodenum) through the PYLORIC SPHINCTER.
pyloric sphincter releases chyme from the stomach into the small intestine.
duodenum The first section of the small intestine releases two hormones: -secretin -cholecystokinin (CCK)
secretin travels to the pancreas to trigger release of bicarbonate, which neutralizes the stomach acid entering the duodenum. In addition, secretin triggers the release of pancreatic enzymes that further aid chemical digestion in the small intestine.
cholecystokinin (CCK) -initiates bile release from the gallbladder, while decreasing mtility and acid production by the stomach.
Additional enzymes needed to complete the digestion of fats, proteins and carbohydrates are released.
Majority of absorption occurs where? in the small intestine through finger-like projections called VILLI.
Villi and MICROViLLi Increase the surface area within the small intestine, increasing the area from which absorption can take place.
Parts of villi -Each villus contains arterioles and lymphatic vessels through which absorption occurs.
When not absorbed... -The remaining products of digestion that are not absorbed are transported to the colon.
Large Intestines -Absorption of water, which affects water and electrolyte balance, occurs in the colon, and the storage and formation of feces also occurs.
Immune System tissues, cells and organs that fight off illness and disease.
Immune System is composed of both innate (nonspecific) and adaptive (specific) defenses that are designed to protect the body from PATHOGENS and other foreign invaders.
Innate immune functions provide a nonspecific type of defense.-These defense mechanisms occur the same way every time, regardless of the type of number of pathogens that are present.
Innate defenses--first line of defense -skin-mucous membranes-digestive enzymes (which includes both physical and chemical barriers)
Innate defenses - second line nonspecific defenses: -fever-inflammation-phagocytosis (engulging of pathogens by white blood cells)-natural killer cells-interferons-chemotaxis-release of cytokines
Four cardinal signs of inflammation (innate defenses) -Redness-heat-swelling-pain
Natural Killer cells NK cells (innate defenses) -produce PERFORINS (pore-forming proteins) that target cancer and virus cells.--Perforins cause these cells to LYSE (rupture)
Interferons (innate defenses) Body's response to a viral infection and prevent replication of the virus after 7 to 10 days.- They also activate macrophages and NK cells.
Chemotaxis (innate defenses) the method by which the LEUKOCYTES (white blood cells) respond to damaged body tissues
Chemotaxis: Cytokenes -this is accomplished in part through CYTOKINES (chemical messengers that are released by damaged tissues).
DIAPEDESIS (the process of white blood cells squeeing through capillary slits in response to cytokines) occurs, followed by cellular adhesion molecules (CAMs) guiding the white blood cells to the site of damage or infection.
Adaptive responses Known as the third line of defense, or specific defenses. -humoral (antibody-mediated) -cell-mediated responses
humoral (antibody-mediated) immunity Antibodies are produced that are specific for the invading ANTIGEN.-The antigen binds to B cells (types of lymphocytes or small leukocytes) followed by binding with T-helper cells.--This activates the B cells to produce antibodies.
active immunity individual receives a vaccine that simulates an actual infection by a pathogen, stimulating the body to produce antibodies for future protection.
Passive immunity Individual does not produce his or her own antibodies, receives them directly from another source, such as mother to infant through breast milk.
Cell-mediated immunity T cells are primarily responsible for recognizing nonself cells. -T cell is a lymphocyte that triggers the action of other lymphocytes.
Process of Cell-mediated immunity -macrophages capture the nonself cell -T-helper cell binds to it and secretes a cytokine that signals the cytotoxic T cell-Cytotoxic T cell responds through chemotaxis and actively destroys the nonself cell.
Fertility rate average number of children a woman will have during her childbearing years -occur between the ages of 15 and 44
Replacement rates number of births needed to maintain the population at its current number.
crude birth rate number of births per 1,000 people per year
crude death rate number of deaths per 1,000 people per year.
Immigration moving into a region or country
emigration moving out of one region or country
Biological classification system Eight levels of Taxonomy: Domain - donkey Order - often Kingdom - Kings & Family - find Phylum - princes Genus - great Class - Can Species - spouses
Each taxon becomes less specific. The least inclusive listing is the species and the most inclusive is the kingdom
Six Kingdoms A - Amber F - feels P - positively P - perky
Natural selection (survival of the fittest) some individuals of a species are better able to survive in their environment and reproduce than others.
Genes Responsible for heredity. -Stretches of DNA on a chromosome that provide information for an organism's characteristics.
Alleles a different form of a gene. -some alleles contain one or more MUTATIONS (changes in the DNA that affect the way a gene functions.)
Adaptation Mutations and combinations of alleles that make it easier for the organism to withstand the environmental pressures.
Mutations Permanent changes in DNA sequences.
nucleic acids DNA (deoxyribonucleic acid) RNA (ribonucleic acid)
Nucleic acids job is to store and transmit hereditary information.-Structurally, a nucleic acid is a chain of NUCLEOTIDES than consists of a pentose, a phosphate group, and a nitrogenous base.

G2 phase continued protein synthesis and cell growth in preparation for cell division.
Mitosis occurs to replace old and dying cells with genetically identical ones.-cells double content to pass one complete copy to each daughter cell.
meiosis: gametes cells that form a new organism via sexual reproduction.-gametes from one individual combine its DNA with DNA from another individual.Gametes reduce DNA content of combined DNA in a process called meiosis.
Meiosis purpose is to halve the number of chromosomes.-a benefit of meiosis is that it results in extra genetic variability.
-DIPLOID cells contain two sets of chromosomes.
-HAPLOID cells contain a single set of chromosomes.
HOMOLOGOUS chromosome- in a diploid cell it is the twin chromosome
chromatids (during S phase) individual chromosomes duplicate during the S phase and condense into chromosomes that have both copies of the individual chromosome attached at one spot to form sister chromatids.
cytokinesis separating of the two sets of chromosomes into different cells during Meiois/mitosis (Telophase)
Photosynthesis and Respiration Both result in the formation of cellular energy for an organism, but two processes differ in their end results
Photosynthesis the process carried out by green plants, green algae, and certain bacteria-energy from sunlight is trapped by the green pigment chlorophyll and used for synthesis of glucose.
-chloroplast organelle in plants that allows Photosynthesis to occur.
Photosynthesis --carbon dioxide, water, and energy form the sun are used to produce adenosine triphosphate (ATP)
Autotroph an organism that is able to produce its own food (most use Photosynthesis to live)
Heterotrophs organisms that cannot produce their own food.
Respiration uses one of the end products of Photosynthesis, glucose to produce ATP for cells. (used by Heterotrophs)
Glycolysis Process of breaking down glucose to pyruvate-transfers some of the energy in glucose to ATP.End-products of glycolysis are fed into the citric acid cycle (Krebs cycle) to produce even more ATP.
Kreb's Cycle / TCA cycle / Citric Acid cyle -glycolyisis + citric acid cycle = respiration
respiration chemical equation for cellular respiration is the reverse of that of Photosynthesis.
Hereditary information Chromosomes are located in the nucleus of a cell and contain stretches of DNA called Genes.
Genes contain coded information that controls the heredity of certain traits.-code is made up of the sequences of nitrogenous bases of DNA:
Each piece of code is called a CODON (composed of 3 bases) -there are 64 codons-each codon matches to a specific AMINO ACID. (20 different amino acids)A chain of amino acids then forms a protein.
genome a complete set of DNA for an individual that contains all genes.
mutagen a substance that induces mutations(harmful chemicals, ultraviolet rays from the sun)

Catalysts control the rate of chemical reactions, or reactions in which atoms react to come to a stable state.-catalysts increase reaction rates by lowering activation energy.
substrate the molecular surface acted upon by an enzyme
general catalytic reaction process In this process, the catalyst (C) generates a product (Z) from the reactants (X and Y). Notice that the catalyst is present with the product, and is thus available to continue the reaction anew. 1) X + C → XC 2) XC + Y → XYC 3) XYC → CZ 4) CZ → C + Z

Heat the flow of energy due to a difference in temperature
Liquid to gas: through evaporation or vaporization, requires an addition of heat.
gas to liquid: through condensation requires a subtraction of heat.
evaporation of a liquid often achieved due to the high heat, low humidity and fast movement of surrounding air mass.
-physical collisions at surface layer of a liquid. --removes faster moving molecules, removing more energetic atoms from liquid.Results in cooler system.
phase transition an alteration of the physical state between a solid, liquid, and gas.
vaporization occurs through a phase transition from a liquid to gas.
Phase Transition -transition from a liquid to a gas takes place by breaking the physical bonds within the liquid.-Amount of heat (H) for this phase depends on mass (M) and latent heat (L)
Latent heat Latent heat is the heat released or absorbed by a chemical substance or a thermodynamic system during a change of state that occurs without a change in temperature, meaning a phase transition such as the melting of ice or the boiling of water.
Vaporization Example Suppose a 100-gram (g) mass of water is at the boiling point. Given that the latent heat of water is 540 calories/gram (cal/g), the amount of heat added to fully vaporize the liquid can be calculated by:
H=M x L =100g x 540 cal/g =54,000 cal =54 kilocalories
condensation example H=-M x L condensation occurs through a phase transition from a gas to a liquid-creating physical bonds within the gas
