Which of the following is NOT involved in short-term regulation of blood pressure?

A) Baroreceptor reflex
B) Adrenal medullary mechanism
C) Alteration in blood volume
D) Chemoreceptor mechanism

Chemoreceptor Mechanism

The chemoreceptor mechanism is a physiological process involving receptors that detect changes in chemical concentrations, such as oxygen and carbon dioxide levels, and mediate corresponding responses.

Adrenal Medullary

Pertaining to the inner region of the adrenal gland, which produces adrenaline and noradrenaline, hormones involved in the body's fight-or-flight response.

Blood Volume

The total volume of blood circulating within an individual's cardiovascular system, critical for adequate perfusion of tissues and organs.
