
Digestion is the breakdown of
nutrients to a level that can be used
by cells of the body.

Human Endocrine System

The endocrine system consists of ductless
glands that produce hormones.


Hypothalamus, pituitary, pineal, thyroid,
parathyroid, thymus, adrenal, pancreas, ovary,
testes
Hormones are chemical messengers that
travel through the blood stream and
affect activities throughout the body.
