Which Body part does not have bones?

The body part that does not have bones is cartilage. Cartilage is a type of connective tissue that is found in many parts of the body, including the ears, nose, trachea, and joints. It is made up of specialized cells called chondrocytes that are embedded in a matrix of collagen and other proteins. Cartilage is flexible and elastic, and it helps to protect bones from damage. However, it is not as strong as bone and does not contain any blood vessels or nerves.
