Endocrine System Functions
•Regulates many bodily functions
•Maintains homeostasis by regulating the production
of chemicals that affect most functions of the body
•Secretes substances that aid the nervous system
•Important regulator of growth and development
•Endocrine glands are ductless glands, unlike
exocrine glands that secrete substances into ducts.
Endocrine System Structures
 Glands
– release products to bloodstream
directly.
 Horomones – products deliver messages
to body
 Target cells – have specific receptors for
specific hormones
Endocrine Glands
Section 39-1
Hypothalamus
The hypothalamus makes
hormones that control the
pituitary gland. In addition, it
makes hormones that are stored
in the pituitary gland.
Pituitary gland
The pituitary gland produces
hormones that regulate many of the
other endocrine glands.
Parathyroid glands
These four glands release
parathyroid hormone, which
regulate the level of calcium
in the blood.
Thymus
During childhood, the thymus
releases thymosin, which
stimulates Tcell development.
Adrenal glands
The adrenal glands release
epinephrine and nonepinephrine,
which help the body deal with stress.
Pineal gland
The pineal gland releases melatonin, which
is involved in rhythmic activities, such as
daily sleep-wake cycles.
Thyroid
The thyroid produces thyroxine, which
regulates metabolism.
Pancreas
The pancreas produces insulin and glucagon, which
regulate the level of glucose in the blood.
Ovary
The ovaries produce estrogen and progesterone.
Estrogen is required for the development of secondary
sex characteristics and for the development of eggs.
Progesterone prepares the uterus for a fertilized egg.
Testis
The testes produce testosterone,
which is responsible for sperm
production and the development of
male secondary sex characteristics
