Major Anatomy
The endocrine system is made up of glands that produce and
secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones help regulate the body’s ability to growth and sexual development of the body. Hormones are released and affect the bloodstream and organs through the body.

Glands:
Exocrine: gland that secrets a substance out through a duet. Includes salivary and sweat glands.
Endocrine: dutchless glans/glands that secrets a substance into the blood stream

Definitions:
Steroid Hormones: steroid that acts as a hormone, can be divided into 5 different groups.
Nonsteroid hormones: an organic compound that does not contain a steroid.
Prostaglandins: any group of cycilc fatty acids with hormones like effects, notability the promotion of urine contractions
Homeostasis:tendency of a system, especially in the physilogical system of higher animals to maintain internal stabiloity.
Feedback mechanism: process in which the leve; of none substance influences the levl of another substance..

How the Brain Regulates Hormones:
Role of the Hypothalamus: controls temparature regulation, emotion, sexual behavior, and motivation.
Role of the Pituary Gland: small endocrine gloand organ that controld a multitude of important functi0ons in the body.
Feedback Mechanism: describes the situation ehrn output from an event of phenomenon in the past will influence.

Functions and Locations
Hypothalamus:located in the brain, near the optic chiasm. It releases hormones in the pituitary gland. It also controls water balance, sleep, temperature, appetite and blood pressure.
Pineal Body: located below the corpus callosum, a part of the brain. It produces the hormone melatonin. Pituitary: located in the base of the brain about the average size of a pea, Controls the function of the endocrine glands. Thyroid andParathyroid:located in front of the neck, below the larynx (voice box). Both play important parts in the body’s metabolism and the regulation of the body's calcium balance. Thymus:located in the upper part of the chest. Produces T-lymphocytes (white blood cells that fight infections and destroy abnormal cells). |
Adrenal Gland:located at the top of both kidneys. Adrenal glands work with the hypothalamus and pituitary gland.
Kidney:located near the middle of the back below the rib cage. The kidneys process the blood to sift out waste products and extra water which later on becomes urine. Pancreas: located across the back of the abdomen, behind the stomach. Helps out in digestion and hormone production. Ovary: located on both sides of the uterus, below the opening of the fallopian tubes. Creates the eggs necessary for reproduction. They also produce estrogen and progesterone. Testis:located in a pouch that hangs suspended outside his body. The testes produce testosterone and sperm. |
