Biology

Leya [2.2K]3 years ago
7 0

Answer:

Answer is C.

Explanation:

A. The vessel length is pretty much constant. The body can't length or shorten blood vessels.

B. Blood viscosity is also fairly constant because the composition of blood cannot change quickly enough to change resistance as needed.

C. This is the main way resistance is controlled. The smooth muscle surrounding blood vessels can rapidly respond to hormonal or metabolic stimuli and contract/relax to adjust diameter.

D. Again, temperature is fairly constant in the body and would not be a good way to alter resistance.

It is best for the nurse to calm the client by having to tell him or her that the nurse will leave and will be back as soon as he or she calms down.
