What does a bursa reduce within the body?

Flexibility
Friction
Strength
Stability

The correct answer is: Friction

The correct choice is connected to the vital role that bursae play in the musculoskeletal system. A bursa is a small, fluid-filled sac located between structures such as bones and tendons or muscles. Its primary function is to reduce friction, allowing these structures to glide smoothly over each other during movement. When muscles or tendons move over bony surfaces, they can create significant friction. By containing synovial fluid, bursae cushion these interactions and facilitate smoother motion, which is essential for maintaining joint function and preventing wear and tear on the tissues involved. Consequently, the reduction of friction helps to minimize discomfort and the risk of injuries such as tendonitis or bursitis that can arise from excessive friction in areas where muscles or tendons rub against bone. The other options do not accurately represent the primary function of bursae. Flexibility, strength, and stability are influenced by various anatomical and physiological factors, but the specific role of a bursa is to alleviate friction in the body.
