Has to do with your bodily functions?

Im pretty sure there are a variety of organs/ muscles that help your body function so I’m going to name a few.

The heart, the lungs, the stomach, and the brain.

But out of all of these I think the heart is one of the main body functions because it pumps blood throughout your body keeping you alive in the process.

There are eight major endocrine glands, each with a different function: pituitary gland: the “brain” of the endocrine system; regulates all seven of the other glands and secretes growth hormone.thyroid: regulates a person’s metabolic rate, which is the amount of energy expended daily by a person at rest.thymus: assists in the development of a person’s immune system.adrenal gland: regulates fluid and sodium balance within the body, and secretes epinephrine (“adrenaline”) when the body is under stress, producing the fight-or-flight response.ovaries (in females) and testes (in males): control the development of secondary sex characteristics.pancreatic islets: regulate blood sugar.pineal gland: regulates biorhythms and mood, and stimulates the onset of puberty.
