Facts related to the endocrine system | Facts muscular system
The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
Endocrine glands of human body are divided into two categories;
1) Typical endocrine glands,
2) Organs having secondary endocrine function.
# TYPICAL ENDOCRINE GLANDS : These glands have primary function of producing hormones for human body.
Typical endocrine glands include:-
PITUITARY GLAND
THYROID GLAND
PARATHYROID GLANDS
ADRENAL GLANDS
# ORGANS HAVING SECONDARY ENDOCRINE FUNCTION : These organs primarily belong to some other system of the body but have a secondary function of producing hormones. They include;
PANCREAS(Hormones of Pancreas)
OVARIES (In females) (Hormones of Ovaries)
TESTES (In males) (Hormones of Testes)
KIDNEYS (Hormones of Kidneys)
LIVER (Hormones of Liver)
Diseases related to the endocrine system
Hormone levels that are too high or too low indicate a problem with the endocrine system. Hormone diseases also occur if your body does not respond to hormones in the appropriate ways. Stress, infection and changes in the blood's fluid and electrolyte balance can also influence hormone levels, according to the National Institutes of Health.
Common Endocrine Disorders-
Type 1 Diabetes.
Type 2 Diabetes.
Osteoporosis.
Thyroid Cancer.
