b. decrease insulin secretion. d. remove glucose from the blood.

b. decrease insulin secretion.

Physiology is the study of the ____________ of a living organism.

Function

The level of insulin will rise after eating but will soon drop to normal levels when blood glucose levels return to normal. This is an example of _____________________.

negative feedback

When the blood begins to clot, the chemical reactions involved in the process will continue until the clot is completed. This is an example of _________________.

positive feedback

The study of the structure of a living organism is ________.

anatomy

___________ is the relatively constant state maintained by the body.

Homeostasis

Blood vessels will dilate in an attempt to release body heat and they will constrict in an effort to retain body heat. This is done to try to maintain the correct body temperature. This is an example of ___________
