The increased production of _____ that results from training increases the oxygen-carrying capacity of the blood.
A)red blood cells
B)capillary blood vessels
C)white blood cells
D)endoplasmic reticula

Question

The increased production of _____ that results from training increases the oxygen-carrying capacity of the blood. 
A)red blood cells
B)capillary blood vessels
C)white blood cells
D)endoplasmic reticula

Quizplus · Accepted Answer

The oxygen-carrying capacity of the blood is increased due to the production of more red blood cells. Capillary blood vessels and white blood cells do not contribute to oxygen-carrying capacity. Endoplasmic reticula are involved in protein synthesis and do not play a direct role in oxygen-carrying capacity of the blood.
