The primary function of cartilage in the body is to absorb shock and reduce friction. Cartilage is a flexible and resilient connective tissue that plays a crucial role in joints by providing a cushioning effect between bones. This is important in areas like the knees, elbows, and spine, where the joints experience significant pressure and movement. The smooth, slippery surface of cartilage helps to minimize wear and tear during movement, allowing for ease of motion without pain.

In addition to its role in shock absorption, cartilage also helps to maintain the shape of certain structures in the body, such as the ears and nose, and is involved in the growth and development of long bones during childhood and adolescence. Its unique composition, which includes a high proportion of collagen fibers and a gel-like matrix, contributes to its ability to withstand compressive forces and reduce friction, making it essential for the proper functioning of the musculoskeletal system.
