Section 39-1: The Endocrine System
The endocrine system
is made up of glands that release their products into the bloodstream.
These products broadcast messages throughout
Like most systems of the body, the endocrine
system is regulated by feedback mechanisms that function to maintain homeostasis.
Section 39-2: Human Endocrine Glands
gland secretes nine hormones that directly regulate many body functions
and control the actions of several other endocrine glands.
controls the secretions of the pituitary gland.
The thyroid gland
has the major role in regulating the body's metabolism.
the thyroid gland and the parathyroid glands maintain homeostasis in blood
The adrenal glands
help the body prepare for and deal with stress.
Insulin and glucagon
released from the pancreas help to keep the level of glucose in the blood
The gonads serve
two important functions: the production of gametes and the secretion of
Section 39-3: The Reproductive System
The main structures
of the male reproductive system are the testes, the epididymis, the vas
deferens, the urethra, and the penis. These structures work together to
produce and deliver sperm.
The main structures
of the female reproductive system are the ovaries, the Fallopian tubes,
the uterus, and the vagina. In addition to producing eggs, the female
reproductive system prepares the female's body to nourish a developing
