Here's a breakdown:

* Bones: The bones in our body form a rigid framework that provides the primary support for our weight. They act as levers for muscles, allowing us to move.

* Muscles: Muscles attached to the bones help maintain posture and balance, and they contract to allow movement. They contribute to the support of our weight, especially when we are moving or standing.

* Ligaments: These tough, fibrous tissues connect bones to other bones, providing stability and preventing excessive movement. They play a role in supporting the body's weight by holding the bones together.

* Tendons: These strong, fibrous cords attach muscles to bones, allowing muscles to pull on the bones and create movement. They indirectly support the body's weight by transferring forces from muscles to bones.

So, while the skeleton is the primary support system, the muscles, ligaments, and tendons all play crucial roles in maintaining posture, balance, and overall weight support.
