And if our muscle cells are low in calcium, the bone can basically release calcium to the blood that will eventually travel to those muscle cells. So bone is responsible for storing important minerals such as calcium. It also contains adipose tissue that is responsible for storing triglycerides. Now, the final function of the skeletal system is producing our blood cells, and this process is known as hematopoasis. And this takes place in a specialized type of structure within the bone known as the bone marrow. And we'll discuss the structure of the bone in the next lecture.
