Capillary structure is uniquely adapted for exchange processes because
A)there are many of them.
B)they have valves to control flow.
C)they have only one layer of simple squamous epithelium (endothelium).
D)they allow two-way flow.

Question

Quizplus · Accepted Answer

Capillaries have only one layer of simple squamous epithelium (endothelium) which allows for efficient exchange processes due to their thin walls and close proximity to cells and tissues. Valves, two-way flow, and quantity do not necessarily enhance exchange processes.
