A&P 2 BLOOD TEST REVIEW QUESTIONS & ANSWERS
RATED 100% CORRECT.
what are the major components of the blood? Answer - Plasma and formed
elements
What are the formed elements? Answer - Erythrocytes, red bood cells
Leukocytes, white blood cells
Platelets, for clotting
What are the three basic functions of blood and an explanation of each?
Answer - 1) Distribution: blood transports oxygen fro mteh lungs and nutrients
fro mthe digestive tract, metabolic wastes from cells to the lungs and kidneys
for elimination, and hormones from endocrine glands to target organs.
2) Regulation: Blood maintains appropriate body temperature by absorbing
and distributing heat, normal pH in body tissues using buffer systems, and
adequate fluid volume in the circulatory system.
3) Protection:L Blood protects against blood loss by activating plasma proteins
and platelets, initiating clot formation when a vessel is broken and prevents
infection by synthesizing and utilizing antibodies, activating complement
proteins, and activating WBC's to defend the body against foreign invaders.
What are the five general components of blood plasma? Answer - 1) proteins
2) nonprotein nitrogenous substances
3) organic nutrients
4) electrolytes
5) respiratory gases
, What is the pH of blood? Answer - 7.35-7.45
What are erythrocytes and how do their structural characteristics contribute to
their function? Answer - Erythrocytes are red blood cells. They are biconcave
discs, anucleate and have essentially no organelles. They are filled with
hemoglobion, a protein that functins in gas transport. Gas transport is assisted
by the biconcave shape: huge surface area relative to volume and discounting
water content - they are more than 97% hemoglobin. Hemoglobin reversibly
binds with oxygen and most oxygen in the blood is bound to hemoglobin.
What is the function of erythrocytes? Answer - Respiratory gas transport via
hemoglobin.
What is hemoglobin made of and what can it transport? Answer - the protein
globin, which is made up of two alpha and two beta chains, each bound to a
heme group. Each heme group bears an atom of iron. Each atom of iron can
bind to one oxygen molecule, therefore each hemoglobin molecule can
transport four molecules of oxygen.
What are the different types of hemoglobin and how are they different?
Answer - 1) Oxyhemoglobin: hemoglobin bound to oxygen. Oxygen loading
takes place in the lungs.
2) Deoxyhemoglobin: hemoglobin after oxygen diffuses into tissues (reduced
Hb)
3) Carbaminohemoglobin: hemoglobin bound to carbon dioxide. Carbon
dioxide loading takes place in the tissues.
Too much carbon dioxide in the body is called? Answer - Alkalosis - alkaline
environment
