Final answer:
The skeletal system provides support and protection, as well as being a site of blood cell production (hemopoiesis).
Step-by-step explanation:
The body system that provides support and protection as well as being a site of blood cell production (hemopoiesis) is the skeletal system. The skeletal system is comprised of bones, cartilage, ligaments, and tendons, and it plays a vital role in maintaining the structure and shape of the body. In addition to providing support, the skeletal system also protects internal organs, such as the heart, lungs, and brain.
