Definitions:

Sympathetic Stimulation

Activation of the sympathetic nervous system, resulting in physiological responses such as increased heart rate and blood flow to muscles.

Metabolic Rate

The rate at which the body uses energy to maintain basic vital functions such as breathing, circulation, and cell production.

Precapillary Sphincters

Ring-like muscles located at the entrance of capillaries, controlling blood flow into the capillaries by contraction and relaxation.

Interstitial Pressure
