Final answer:
Flexion is the type of movement that occurs when you bend your knee.
Step-by-step explanation:
Flexion is the type of movement that occurs when you bend your knee. Flexion is characterized by a decrease in the angle between the bones of a joint, in this case, the knee joint.
When you bend your knee, the angle between your thigh bone (femur) and your lower leg bone (tibia) decreases. This is an example of flexion.
