The Endocrine System.
The endocrine system consists of hormone-producing glands. Stimulating hormones produced by the pituitary regulate many of these. The pituitary is in turn influenced by releasing hormones secreted by the hypothalamus and is situated at the base of the brain. The hypothalamus-pituitary-thyroid axis is particularly important in PMS.
1. Pineal Gland
Responds to dark and light, and may be linked to sexual development.
Hypothalamic hormones stimulate the pituitary; while the hypothalamus helps control appetite, weight control, sleep, sexual desire, mood and emotion.
3. Parathyroid Gland
Regulates calcium concentration in the blood.
4. Pituitary Gland
Secretes hormones that stimulate the adrenal glands, the thyroid, and pigment producing skin cells and ovaries or testes. It also secretes growth hormone, antidiuretic hormone, prolactin and oxytocin, which partly causes the uterus to contract in childbirth and during periods.
5. Adrenal Cortex
Adrenal cortical-stimulating hormonal (ACTH), produced by the pituitary causes adrenal glands to produce hydrocortisone, which affects the metabolism. They also produce androgens (male sex hormones) and aldosterone, which regulate blood pressure and the body’s salt balance.
6. Thyroid Gland
Helps stimulate metabolism, body temperature and bone growth. It’s activity is controlled by stimulating hormones by the pituitary.
The kidneys’ function are to filter the blood. All the blood in our bodies passes through the kidneys several times a day. The kidneys remove wastes, control the body’s fluid balance, and regulate the balance of electrolytes.
8. Thymus Gland
Plays a vital part in immunity and resistance of infection.
The Duodenum is the first section of the small intestine, and is considered the principal site for iron absorption into the body.
Functions as an important organ of the digestive process.
Produce estrogen and progesterone, which influence virtually every aspect of female physiology including skin, hair, body, composition, bone density and reproductive function. Gonadotriophic hormones produced by the pituitary govern them.
Secretes insulin and glucon, which control energy in the body.
