What are the differences between flexion and adduction in terms of their movements and functions in the human body?

Flexion is the bending movement that decreases the angle between two body parts, while adduction is the movement that brings a body part closer to the midline of the body. Flexion is commonly seen in joints like the elbow and knee, while adduction is often seen in movements of the arms and legs towards the body. Both movements are important for various activities and functions in the human body.
