What does the pelvis do in the human body?

The pelvis plays a crucial role in the human body by providing support for the spine and acting as a foundation for the lower extremities. It consists of a ring of bones, including the hip bones and the sacrum, which together provide structural stability and help bear the weight of the upper body when standing or sitting. This support allows for the proper transmission of forces during movement and activities such as walking and running. Additionally, the pelvis serves as an attachment site for various muscles and ligaments that are instrumental in movement and stability.

The lower extremities, which include the legs, rely on the pelvis not just for support but also for alignment and balance, enabling effective gait and mobility.
