Mammals have a joint in the middle of the leg that is called a knee. In humans this joint allows the leg to bend backwards.
Your knee allows you to walk and bend your leg.
When you bend your leg, the muscles in your thigh contract, pulling on the tendons that are attached to the bones in your lower leg. This causes your knee joint to flex, bringing your lower leg closer to your thigh. Additionally, the bones in the knee joint glide and rotate to allow for smooth and efficient movement.
