Heart Rate

Heart rate is the number of heartbeats per unit of time, typically expressed in beats per minute (bpm), indicating the speed of heart function and cardiovascular health.

Vasoconstriction

The narrowing of blood vessels, which decreases blood flow and is regulated by various mechanisms in the body for maintaining blood pressure and temperature.

Sympathetic Fibers

Nerve fibers of the sympathetic nervous system that prepare the body for physical activity by increasing heart rate, blood flow, and energy mobilization.

Parasympathetic Fibers

Nerve fibers of the parasympathetic nervous system, responsible for conserving energy and slowing down the heart rate among other functions.
