Systems Quiz Review

TermDefinition
How many Systems do you have 3
Where does the glucose come from? Food
Where does the oxygen come from? Breathing
What are the final products of cellular respiration? CO2 H2O ATP
In which organelle does this take place in our cells? Mitochondria
Name the system that starts with a D Digestive System
Name a system that starts with a C Circulatory
Name a system that starts with a R Respiratory System
Digestive system begins a the Mouth
What is Chemical Digestion Salivary glands produce amylase which begins to break down sugars and starches
What is Mechanical Digestion teeth grind and break down food into smaller pieces.
What is Esophagus moves food from mouth to stomach using peristalsis
What is the small intestine Absorption of food molecules into the blood takes place here
What is the Villi Inner surface of small intestine heavily folded and lined with small finger like projections.
What is the purpose of the Human Digestive System? Converts food into simpler molecules that can be used by the cells of the body; absorbs food and eliminates waste.
What is the stomach Food combined with acids and enzymes; the stomach muscles squeeze and contract
What is Chyme Partially digested food
What is Cardiac Sphincter Ring of muscles at top of stomach to keep food inside
What is pyloric Sphincter Ring of muscle at bottom of stomach to keep food pushed into small intestines from re-entering stomach
Large Intestines absorbs water and compacts waste
What is rectum/anus Releases wastes outside the body
What are the accessory organs to the Digestive system Pancreas and Liver
What is a pancreas Produce insulin and glucagon to regulate blood sugar levels
What is a liver Produce bile, aids in the digestion of fat
Where is bile stored In a pouch under the liver, the gall bladder
What is Glucose a Primary source of energy for the body
Constant supply of glucose should be maintained where? the blood, but must be kept in balance so as not to damage cells.
What are Hormones? produced by pancreas, glucagon and insulin, help cells maintain homeostasis with regard to blood sugar.
What is the purpose of the respiratory systems provider o2 to the blood for cellular respiration in the cells and removes CO2, from the body
How does the respiratory system exchange gas? through the walls of the sacs of the lungs
What does the Nasal Cavity (Nose) do? Warms, filters, moistens air as it passes over mucous membrane.
What does the Pharynx (throat) do? Located where the passages from the nose ad mouth come together.
What is Epiglottis? Flap of elastic tissue that forms a lid over the opening of the trachea.
What is the Larynx (Voice Box) is located ? between the pharynx and the trachea
What does the Larynx contain? Two ligaments - vocal cords that produce sound when air moves through them.
What is the Trachea (windpipe) Tube through which air moves from the pharynx to the lungs
What is a Diaphragm Sheet of muscle below the lungs that separate the chest cavity (thorax) from the abdominal cavity.
What does the Diaphram do? It contracts and relaxes to help inflate and deflate the lungs.
What is the internal Respiration ? The process by which cells get energy from the breakdown of glucose in the presence of oxygen.
When does internal respiration occur? in the Mitochondria
What is Bronchi Two short tubes which direct air into right and left lungs.
What is Bronchioles Millions of smaller tubes that branch off each Bronchi
What is Alveoli Small Sacs found at the end of the bronchioles that are surrounded by capillaries
What is Breathing? the movement of the air into and out of the lungs.
What is External Respiration? The exchange of Oxygen and CO2 between the blood in the capillaries of the alveoli and the air.
Where does the External Respiration occur In the Lungs
After food is broken down /digested, what system do the molecules diffuse to? Circulatory
After you take a breath, in to what system does the oxygen diffuse to? Circulatory
Human Circulatory System purpose is To transport oxygen and nutrients to all the cells in the body and to take carbon dioxide and wastes away from the cells of the body.
Human Circulatory System structure consist of ? Heart and blood vessels
What is the Heart? Main organ that pumps blood
What is the Blood vessels? Tubes through which blood travels
What is blood? .Liquid including read and white blood cells and platelets
What is plasma? thick, yellowish liquid in which blood cells are suspended
What is red blood cells? Carry O2 and remove CO2 (Transported by the protein hemoglobin)
What is white blood cells? Help fight disease
What is platelets? Help form blood clots
What are arteries? Carry blood away from heart
What are veins? Carry blood toward heart
What are capillaries ? Smallest blood vessels; where exchange of nutrients and wastes takes place by diffusion.
What do plasma do? Liquid part of blood. A dilute solution of salts, glucose, amino acids vitamins, urea, proteins and fats.
What does White Blood Cells do? Involved in Immune system
What does Platelets do ? Involved in blood clotting
What does Red Blood Cells do? involved in carrying oxygen
Open Circulatory System is Blood is only partially contained within a system of blood vessels.
What is Single Loop Circulation Most single loop vertebrates use gills for respiration and forces blood around body in one direction.
What is Double Loop Circulation Located in vertebrates that uses lungs for respiration
Closed Circulatory System Heart or heart - like organ forces blood through vessels that extend throughout the body.
What is First Loop? Carries blood between heart and lungs.
What is the Second Loop? Carries blood between heart and body
Nervous System Maintains homeostasis by controlling and regulating all other parts of the body.
Function of the Nervous System consists of Sensory, Interpretation, and Response
What is a Sensory? Users receptors to gather information from all over the body.
What is Interpretation? the brain then processes the information into the possible responses
What is Responses Sends messages back through the system of nerve cells to control body parts.
What is a Neurons? The functional
