Is the skeletal system interdependent on the integumentary system?


A. Yes, the skeletal system is interdependent of the integumentary system. The main objective is the bones rely on the skin for the synthesis of vitamin D3. Without vitamin D3 (a steroid that is converted to calcitriol), a normal calcium metabolism wouldn’t be maintained). Calcium is one of the hearts of bone structure; with a lack of calcium, the bones would become very brittle and lead to cases such as osteoporosis and multiple fractures.

B. No, because the skeletal system consists of both fused and individual bones supported and supplemented by ligaments, tendons, muscles, and cartilage. It serves as a scaffold that supports organs, anchors muscles, and protects organs such as the brain, lungs, and heart. And the integumentary system is the organ system that protects the body from damage, comprising the skin and its appendages (including hair, scales, feathers, and nails). So, therefore, we need the integumentary system to protect the skeletal system at all times, when we move our skin moves.

C. Yes, the skeletal system is interdependent on the integumentary system. One function of the integumentary system is to synthesize vitamin D3. The skeletal system depends on the synthesis of vitamin D for bone growth and bone remodeling by the osteoblast and osteoclast. Vitamin D is needed to absorb calcium into the circulatory system from the digestive system.
