What system gives the body shape and support?

The skeletal system is responsible for giving the body its shape and providing structural support. It consists of bones, cartilage, and ligaments, creating a framework that supports the body and protects internal organs. The skeletal system not only shapes the body's appearance but also plays a crucial role in movement, as it serves as an anchor for muscles and works in conjunction with the muscular system to facilitate locomotion and other physical activities. Additionally, it acts as a reservoir for minerals such as calcium and phosphorus and houses bone marrow, where blood cells are produced. This multifunctional aspect reinforces the importance of the skeletal system in maintaining overall body integrity and function.

The other systems listed do not fulfill the primary role of providing shape and support. For instance, the nervous system is primarily responsible for transmitting signals between different parts of the body, the cardiovascular system focuses on transporting blood and nutrients, and the muscular system facilitates movement but relies on the skeletal framework for support.
