The primary function of platelets is to:
a. Defend the body against bacterial invasion.
b. Carry oxygen to tissues.
c. Facilitate blood clotting.
d. Regulate acid-base balance.
ANS: C
Whenever disruption occurs to a blood vessel so that bleeding results, platelets respond initially to stop the bleeding in small vessels; they also play an integral role in facilitating the formation of a blood clot. White cells defend against bacterial invasion; red cells (i.e., hemoglobin) carry oxygen to tissues; and a complex interaction of plasma electrolytes, proteins, and carbon dioxide participates in acid-base balance.
