What type of tissue is cartilage and what is its primary role in the body?

Cartilage is classified as a type of fibrous connective tissue, which plays a crucial role in the body by supporting structures and providing cushioning at joints. Its unique composition allows it to be both flexible and resilient, enabling it to withstand pressure and provide shock absorption in areas where bones meet, such as in the knees, hips, and shoulders. This supportive role is vital for facilitating movement and maintaining the integrity of the skeletal system. Unlike bone, cartilage does not have a direct blood supply, which contributes to its differing properties and healing capabilities. The other types of tissues mentioned in the choices have distinct functions unrelated to the supportive and cushioning roles of cartilage.
