Skin and Bones

Both the integumentary system and the skeletal system are essential for maintaining homeostasis, and for human survival. One of the main functions of both systems is protection. The integumentary system protects underlying tissues and organs from diseases and temperature change. Similarly, the skeletal system also protects the body. The rib cage and sternum helps protect the lungs and heart. The skull helps protect your brain. Thus, both systems work together in order to protect the body from harm and help to maintain homeostasis.

Both systems also work to help the body move. The skeletal system is composed of joints, cartilage, and ligaments that make it possible for bones to move. The connective tissue in the dermis layer of the integumentary system helps the skin stretch, to accompany the moving of the bones.

The integumentary system also absorbs and synthesizes Vitamin D. It then sends this vitamin D to its best friend, the skeletal system, to be stored. Vitamin D helps the bones absorb calcium and therefore become stronger. Without the integumentary system, the skeletal system would lack this important nutrient and become more susceptible to diseases such as osteomalacia and rickets.

Each of these systems relies on the other to operate properly and efficiently. They both work together to maintain homeostasis and keep us alive. Thanks bones and skin!
