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.
Any interference with normal hormonal functioning is soon apparent as a skeletal abnormality or malproportion. Integumentary System The skeletal system is absolutely dependent on the integumentary system (the skin) for the calcium that keeps the bones hard and strong. The relationship is indirect: In the presence of sunlight, a vitamin D precursor is produced in the dermal capillary blood. It is activated elsewhere, and (among its other roles) it regulates the carrier system that absorbs calcium from ingested foods into the blood.
