A detailed description of a wound suture and the suture materials used in it is by the Indian sage and physician Sushruta, written in 500 BC. The Greek father of medicine, Hippocrates, described suture techniques, as did the later Roman Aulus Cornelius Celsus.
The skeletal system of human helps maintain homeostasis by producing new red bloods cells where the old ones just die off. It also helps maintain the level of calcium in the blood stream.
In biology, the term homeostasis refers to the ability of the body to maintain a stable internal environment despite changes in external conditions. The stability, or balance, that is attained is called a dynamic equilibrium; that is, as changes occur, the body works to maintain relatively uniform conditions. Controlling such things as body temperature, blood pH, and the amount of glucose in the blood are among the ways the body works to maintain homeostasis.
