to the outside of the body. The urethra functions to both male and female bodies. It also functions as a passage for semen. There are two different types of sweat glands, the apocrine sweat glands and the merocrine sweat glands. Both sweat glands contain "muscle" cells. Humans have two lungs, the left lung being divided into two lobes and the right with three. Lungs are what make you breathe and they also absorb water vapors.

It works with the digestive system to help get rid of wastes that you eat through the anus.
