BIO202 Final Exam Study Guide (StraighterLine
A&P II)
1. Viscosity of Blood?: twice as thick as water
2. How long does it take for a drop of blood to circulate through the entire system?:
20-60 seconds
3. What is the composition of Blood: 55% plasma, 45% formed elements,
4. What are the fucntions of blood?: -Moves regulatory and processed molecules,
gasses, waste, and nutrients
-Regulats pH and osmosis process
-Maintain body temperature
-Protect against foreign substances
-Assist in clotting
5. What is the composition of plasma?: 91% water 7%
proteins
2% other solutes
6. What proteins are found in blood plasma?: albumin, globulins, fibrinogen
7. What solutes are found in blood plasma?: Ions, nutrients, waste products,
gasses, regulatory substances
8. What are two blood disorders: Anemia and sickle-cell disease
1/
9
, 9. What is sickle-cell disease?: an abnormal red blood cell that has a crescent
shape and an abnormal form of hemoglobin
10.What is anemia?: a decrease in the oxygen-carrying ability of the blood
11. How much blood does the heart pump per minute?: ~5 1/4 Quarts per minute
12.What are action potentials?: Sequence of electrical changes when a nerve
membrane receives a stimulus that exceeds a threshold
13.What is depolarization?: Loss of an electrical charge on the surface of a
membrane
14.What is Repolarization?: Gain of electrical charge on the surface of a mem-
brane
15.What are the functions of the heart?: generating blood pressure, routing
blood, ensuring one-way blood flow, regulating blood supply
16.What are the two divisions of the heart?: Pulmonary Circuit and Systemic
Circuit
17.What are the components of the heart?: Pericardium, Heart Wall, Chambers,
Valves
18.What is the pericardium?: Double-walled sac that surrounds the heart and
reduces friction between pericardial membranes
19.What is the heart wall?: Three protective layers of tissue
20.What to chambers of the heart do?: Receive and return blood from and to the
body
