How is the skeletal system involved with the delivery of food oxygen and the removal of waste in the human body?

The skeletal system plays a supportive role in the delivery of oxygen and nutrients and the removal of waste, primarily through its relationship with the circulatory system. Bone marrow within the bones produces blood cells, including red blood cells that transport oxygen from the lungs to tissues. Additionally, the skeletal system provides structure and protection for vital organs involved in digestion and waste elimination, such as the intestines and kidneys. While it doesn't directly participate in these processes, its structural integrity is essential for overall bodily function.
