Endocrine System Flashcards

Flashcards about the endocrine system

Endocrine System

Responsible for coordinating specific activities of cells and tissues by releasing hormones into the body.

Endocrine Glands

Create and secrete hormones into the bloodstream.

Exocrine Glands

Create and secrete substances onto a surface like sweat, saliva, and oil.

Adrenal Glands

Located atop the kidneys, secrete epinephrine and norepinephrine to elevate blood pressure, heart rate, and blood sugar.

Epinephrine and Norepinephrine

Hormones that help to elevate blood pressure, heart rate, and blood sugar. Secreted when the body is under stress.

Pineal Gland

Responsible for the production of melatonin, the hormone that regulates the body's wake/sleep cycle, also known as the circadian rhythm.

Pituitary Gland

Secretes growth hormone, prolactin, and follicle-stimulating hormone.

Hypothalamus

Produces dopamine, which increases blood pressure and heart rate. Considered the reward center hormone.

Ovaries

Female gonads that create estrogen and progesterone.

Pancreatic Islets

Create glucagon (increases blood sugar) and insulin (decreases blood sugar).

Testes

Male gonads that secrete testosterone.

Thyroid

Produces calcitonin, which decreases the levels of calcium in the blood stream, preventing weakening of the bones and kidney stones.
