Endocrine system

Endocrine system

A system in the body made up of glands that secrete hormones directly into the bloodstream.

Hormones

Chemical messengers produced by glands in the endocrine system that target specific cells.

Pancreas

An organ located in the abdomen that regulates blood sugar levels and plays a role in digestion.

Pituitary gland

A pea-sized structure located at the base of the brain that links the nervous system to the endocrine system and produces hormones to regulate various functions in the body.

Kidney

An organ that filters waste products from the blood and reabsorbs useful substances.

Anterior lobe

The front part of the pituitary gland that produces hormones such as growth hormone, thyroid-stimulating hormone, adrenal-stimulating hormone, FSH, LH, and prolactin.

Posterior lobe

The back part of the pituitary gland that produces hormones such as oxytocin and ADH.

Insulin

A hormone produced by the pancreas that helps take glucose into cells for energy and stimulates the liver to convert glucose into glycogen.

Glucagon

A hormone produced by the pancreas that stimulates the liver to convert glycogen back into glucose when blood glucose levels are low.

Negative feedback mechanism

A regulatory process in which deviations from normal blood glucose levels are detected by the pancreas, triggering the release of hormones to bring glucose levels back to the normal range.
