thyroid gland- it signals your cells to burn energy. Hyper-thyroid. high metabolism. you have to eat a lot in order to keep up with your body. Hypo-thyroid--> low metabolism (the body stores the energy causing you to gain weight.

the adrenal gland- releases adrenaline. --> your heart rate increases, your blood flow. Sugar into your blood, nutrients you need..

adrenaline=epinephrine

Pancreas- it secretes insulin. taking up glucose in the cells. most cells have insulin receptors. (all cells need glucose for energy)

urinary system- kidneys= clean the blood. (kidneys maintain homeostasis) all blood in your body passes through the kidneys. (it serves as a filter) it's made up of a series of tubes. small stuff gets out of the blood and into the kidney. --> this includes good stuff. the way your body works you have spares of most body parts.

kidney--> pumps blood back into the blood. the kidney extracts it from the blood to through the urine.

kidney stone--- crystals of mineral that build up in the kidney. You have to pass it through the urethra.
