Question

multiple choice question
abnormal red blood cell counts (rbccs) have which consequence on health?
o altered ability to fight infection
o altered ability to clot blood
o altered heart rate and contractility
o altered oxygen - carrying capability of blood

Explanation:

Red blood cells are mainly responsible for transporting oxygen in the blood. Abnormal RBC counts will directly affect the blood's oxygen - carrying capacity. White blood cells fight infection, platelets are involved in blood - clotting, and the heart rate and contractility are mainly regulated by the cardiovascular system and nervous system, not directly by RBC counts.

Answer:

Altered oxygen - carrying capability of blood
