Hormones regulate the function of their target cells
A hormone receptor is a receptor protein on the surface of a cell or in its interior that binds to a specific hormone

Epinephrine is a "fight or flight" hormone, and plays a central role in the short-term stress reaction. It is released from the adrenal glands when danger threatens or in an emergency.
It increases blood pressure and blood sugar levels

A feedback mechanism is a process where the level of one substance or activity of an organ/structure influences another substance or structure in some manner.
Dynamic equilibrium or homeostasis results from the ability of organisms to detect and respond to stimuli.

Temperature Homeostasis
Humans maintain a relatively constant body temperature of about 37° C.
•when we "heat up" we sweat if possible •the evaporation of this perspiration returns the body to its original temperature •When we are too cold we shiver

growth hormone, resulting in abnormal enlargement of the
extremities—nose, jaw, fingers, and toes; in children, the disorder
produces gigantism.
