Endocrine GlandsEndocrine Glands A gland that secretes a substance (a

hormone) into the bloodstream. The endocrine glands are "glands of internal secretion." They include the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroid glands, heart which makes atrial-natriuretic peptide, the stomach and intestines, islets of Langerhans in the pancreas, the adrenal glands, the kidney which makes renin, and calcitriol, fat cells . the testes, the ovarian follicle and the corpus luteum in the ovary.

PancreasPancreas The pancreas is a long flattened

gland located deep in the belly abdomen. Because the pancreas isn’t seen or felt in our day to day lives, most people don't know as much about the pancreas as they do about other parts of their bodies. The pancreas is, however, a vital part of the digestive system and a critical controller of blood sugar levels.

TestisTestis

The male sex gland, located behind the penis in a pouch of skin called the scrotum. The testes produce and store sperm and are also the body's main source of male hormones, such as testosterone. These hormones control the development of the reproductive organs and other male characteristics, such as body and facial hair, low voice, and wide shoulders. Also known as testicle.

OvariesOvaries The female gonad, one of a pair of

reproductive glands in women. The ovaries are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries produce eggs (ova) and female hormones. During each monthly menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a fallopian tube to the uterus. The ovaries are the main source of female hormones, which control the development of female body characteristics, such as the breasts, body shape, and body hair. They also regulate the menstrual cycle.
