What is the role of cartilage in the human body?

Cartilage plays a vital role in the human body by providing support and cushioning in various structures. It is a flexible yet strong connective tissue that helps maintain the shape of certain parts of the body, such as the nose and ears, while also serving as a shock absorber in joints. This reduces friction between bones during movement, allowing for smoother and pain-free motion. In joints, cartilage can protect bony surfaces from wear and damage, which is particularly important in areas subjected to high forces, such as the knees and hips. Overall, cartilage is essential for maintaining joint health and overall bodily function by ensuring that various parts can operate effectively together.
