Final answer:
Connective tissue that is softer and more flexible than bone is known as cartilage, a key component of the skeletal system responsible for maintaining posture and protecting organs. It provides a smooth surface for the movement of bones at joints and differs from bone in its lower calcium content.
Step-by-step explanation:
The connective tissue that supports the body and is softer and more flexible than bone is known as cartilage. Cartilage is a dense connective tissue made of tough protein fibers, which makes it strong but still allows for flexibility. It is found in various parts of the body including the joints, where it provides a smooth surface for the movement of bones.
Cartilage is an essential component of the skeletal system, which includes bones, cartilage, and ligaments. This system is responsible for maintaining the body's posture and protecting internal organs. Unlike bones, cartilage does not contain as much calcium, which is what makes bones rigid and cartilage comparatively softer and more flexible.
There are two major forms of supportive connective tissue: bone, or osseous tissue, and cartilage. Both bone and cartilage have organic matrix material that provide the necessary strength and flexibility for the body's structures and functions.
