Chapter 5 Heart & Blood Vessels Functions for the Cardiovascular System: Transport Blood to Blood Plasma. Blood Plasma Blood being circulated formed elements.
4 Types of circuits: 1. Systemic Circuits 2. Coronary Circuits 3. Pulmonary Circuits 4. Fetal Circuits
Systemic Circuits serving the REST OF THE BODY
Coronary Circuits serving the Heart
Pulmonary Circuits GAS EXCHANGES at the LUNGS
Fetal Circuits serving the FETUS
3 Types of blood vessel: 1. Arteries 2. Capillaries 3. Veins
Arteries Transport blood away from the heart.
Capillaries Microscopic blood vessels. Each Capillary consist of multiple capillaries are used for exchange: nutrients, cellular waste
Veins carries oxygen & drains blood toward the heart.
Blood contains : Oxygenated Blood & Deoxygenated Blood
Oxygenated Blood has : Rich Oxygen Blood
Deoxygenated Blood has: Poor Oxygen Blood
Arteries carries both : Oxygenated & Deoxygenated Blood
Veins carries both : Deoxygenated Blood & Oxygenated Blood
The Heart consist 4 Chambers 2 Atria: Right & Left Atrium 2 Ventricles: Right & Left Ventricles
Right side of the Heart transport: Deoxygenated Blood (Poor Oxygen Blood) through the Right Atrium & Right Ventricle.
Left side of the Heart transport: Oxygenated Blood (Right Oxygen Blood) through the Left Atrium & Left Ventricle.
Systole: Heart Contraction
Diastole: Heart Relaxation
Cardiac Cycle: Reflects the mechanical component of the our heart.
All 4 Chambers of the Heart can: Relax(Diastole) simultaneously.
But All 4 Chambers of the Heart cannot: Contract(Systole) simultaneously.

What controls the Electrical Component of the Heart 3 consist: 1.Cardiac Muscle 2.Nervous System 3.Endocrine System
Intrinscic Control Mechanism Cardiac Muscle
Extrinsic Control Mechanism Nervous System Endocrine System
2 Organ Systems of the Electrical Component of the Heart 1.Nervous System 2.Endocrine System
P wave deflection is followed by Arial Systole means: Both areas of the contracting (Systole)
QRS wave contains 2 things: Artial Diastole & Ventricular Systole
Arial Diastole means Both Arials are Relaxing
Ventricular Systole means Both Vintriculars are Contracting
T wave deflection is followed by Ventricular Diastole means Both Ventricles are Relaxing

Blood contains Blood Plasma & Formed Element
Blood Plasma consist 92 % of water
Formed Elements Formed of Blood contians Erythrocytes, Leukocytes and Platelets
Erythrocytes are Red Blood cells without a nucleus and Mitochondria

Protective Barrier Complements Inferons
Complements punture the surface of Bacteria
Inferons one released by infected body cells to notify Non-infected body cells about presence of virus in the body
Humoral Immunity Is mediated by B-cells (B Lymphocytes)
Celluar Immunity Is mediated by T-cells (T Lymphocytes)
B Lymphocytes mediate into Plasma cells Produce & Release Antibodies are Proteins
Proteins coded by genes
There are 5 classes Ig (M), Ig (A), Ig(D), Ig(G), Ig(E)
Ig Immungoblin Antibody

Ig (G) croses the placenta to protect the fetus
T Lymphocytes -helper T-cells (Th-cells) -Cytoxic T-cells (Tc-cells)
Th-cells control both arms of specific immune system
Tc-cells they kill cancer cells, transplated cells, Bacteria infected cells, Virus infected cells, Fungus infected cells
To kill Tc-cells they release 2 Chemicals 1. Perfourm 2. Granzymes
Granzymes induce cells to commit suicide. Fight off intercellular pathogens inside the body cells Effect only against Extracellular pathogens
Chapter 9 : Digestive System "Main function of the Digestive System": Is to breakdown ingested food we can absorb the nutrient
Humans cannot absorb: Proteins Carbohydrates & Lipids
Function for Proteins Will be digested/ broken down into their building block (amino acids) before we can absorb.
GI tract consist of 4 different type layers/tunes of tissue 1. Mucosa 2. Submucosa 3. Muscular 4. Serosa
Mucosa Mucous Membrane deals with: Food, Taste-Buds, Chyme, & Faces
Submucosa areolar connective tissue beneath the Mucous Membrane
Muscular Smooth Muscle
Serosa the tissue of a serous membrane.
Digestive System function Food, Mouth, Mastication (chewing), Bolus, Swallowing, Esophagus, & ingestion
Walls in the TOP of the Digestive System 1/3 Skeletal Muscle
Walls in the MIDDLE of the Digestive System 1/3 Skeletal & Smooth Muscle
Walls in the BOTTOM of the Digestive System 1/3 Smooth Muscle (only)
The Human Stomach converts bolus into chymes
Bolus function will be converted into chymes
3 layers of smooth muscle in the stomach 1.outer longitudinal 2. the middle circular 3. and the inner oblique muscles.
Chyme will transit through the entire small intestine -Duodenum(10 in) -Jejunum (8 ft) -Ileum (12 ft)

Chp 10 Respiratory System The respiratory system contains: Oxygen (O2) & Carbon Dioxide (CO2)
The Respiratory System is divided into 2 subdivisions of the Upper Respiratory Tract 1. Nose (Nasal Cavity) 2. Pharynx (Throat)
Nasal Cavity starts at the External Nares Front of the Nose
Nasal Cavity ends at the Internal Nares Back of the Nose
Upper Respiratory Tract is divided into 3 regions 1. Nasopharynx 2. Oropharynx 3. Laryngopharynx
Upper Respiratory Tract is lined up by a Mucous Membrane
Upper Respiratory Tract structure Ambient Air -> Nose (Nasal Cavity) -> Nasopharynx -> Oropharynx -> Laryngopharynx
Low Respiratory Tract start at the Larynx
Low Respiratory Tract are vocal cords to produce sound
Low Respiratory Tract structure built from Cartilage
Low Respiratory Tract contains 3 large total pieces: 1. Epiglottis 2. Thyriod Cartilage 3. Cricoid Cartilage

Right Primary Bronchus serves the Right Lungs
Left Primary Bronchus serves the Left Lungs
Right Primary Bronchus split into 3 Bronchus
Left Primary Bronchus split into 2 Bronchus
Each Alveolus is a microscopic structure that allows Gas exchanges between Oxygen (O2) and Carbon Dioxide (CO2)
Pulmonary function can be monitored by 2 sets of Data: Lung Volume Lung Capacity
Tidal Volume is the amount air being displaced by one Breath at rest
Inspirator Reserved Volume is the amount air being forcefully inhaled by one Breath at rest
inhaled volume for Inspirator Reserved Volume 2,900 ml ----------- 2.9 liters
exhaled volume for Inspirator Reserved Volume 1,200 ml ----------- 1.2 liters
Gas Exchanges for External Respiration for Oxygen (O2) Oxygen (O2) goes into the Blood Capillaries from alveoi.
Gas Exchanges for External Respiration for Carbon Dioxide (CO2) Carbon Dioxide (CO2) goes from Blood Capillaries from alveoi
Gas Exchanges for Internal Respiration for Oxygen (O2) Oxygen (O2) leaves the Blood Capillaries moves into body cells

Kidneys transportation both kidney are design to transport to a single urinary bladder.
Both Right & Left Kidneys their walls contain smooth muscle
Smooth Muslce of the Kidney Contract the move urine towards the bladder smooth muscle contrction called perstsis
Single organ called Urinry Bladder contins a thick layers of smooth muscle called Detusor Muscle
Urinary Bladder contains 500ml
Urinary Bladder has 2 circular muscle: 1. Internal Sphincter 2. External Sphincter
Internal Sphincter is Smooth Muscle & Invoultary Control
External Sphincter is Skeletal Muscle & Voluntary Control
Ureathra single organ that is responsible for eliminating & disposing urine
Femle Ureathra is only used by the Urinary System
Male Ureathra is being shared by 2 organ systems 1. Urinary System 2. Reproductive System
3 regions of the Male Ureathra: 1. Prostatic Ureathra 2. Membraneous Ureathra 3. Spongy/ Penile Ureathra
Urine Formation consist of Reanal Corpuscle Proximal Convoluted Tubles Loop of Henles
Urine Formation is preformed by Nephrons
Urinary Formation goes through 3 Stages 1. Glomerular Filration (PCT) 2. Tubular Reabsorption (PCT) 3. Tubular Secration (DCT)
Loop of Henles consist Short Juxtamedullary Long Juxtamedullary
Short Juxtamedullary consist 85%
Long Juxtamedullary consist 15%
Glomerularis is Blood Capillary
Both Kidneys dispose only cellular waste- they keep retain / reaborb to improtant chemical : Glucose, Amino Acids, H20, Sodium (Na)
Kidneys reabsorb 99.5% sodium
Kidneys reabsorb 99% Water
Cellular Waste helps to contract urine to eliminate/dispose the urine
Acid/Base Balance 1. BBS) Blood Plasma 2. Respiratory System 3. Kidneys
