Both the skeletal system and integumentary system share the function of protection. The skeletal system, for example, includes the thoracic cage which protects internal organs, the skull which protects the brain, and also the pelvic girdle which protects the pelvis. So what about the skin you ask? WELL one of the integumentay system's main function is actually protection. The skin is the physical, chemical and water barrier. It protects the inside of the body from physical damage (cuts) and it's also hydrophobic (waterproof) to prevent loss or gain of hydration. The skin also protects the body from damage chemically, for example melanin prevents UV light from penetrating deep tissue! The skin is seriously amazing, obviously. These two systems are physiologically related by their functions and not to mention the skin (along with the muscle and nervous systems) actually protects the skeletal system itself! ---> I have a feeling this is just one example of how ALL the systems that allow our body to function are physiologically related. Which is fascinating to me because if you think about it, we are so perfectly designed? Creation or biological evolution...?
