Bone

It is highly rigid connective tissue that forms the skeleton of vertebrates. They are the type of tissues which comprises of blood vessels and cells. Overall a newborn baby will have around 300 bones and is reduced to 206. The main function of bones are:

1. Serve as a storage of minerals.
2. Provide the structural support.
3. Protect the internal organs of the body.

Cartilage

It is thin, fibrous, flexible connective tissue, which is mainly found in the external ear, larynx, respiratory tract, and the articulating surface of the joints. These cartilages lack blood vessels, therefore the growth and development of these tissues are slower compared to the other tissues. Altogether there are three different types of cartilages and it includes:

1. Hyaline cartilage: It serves as a shock absorber and allows the smooth movement of the bones at joints. They are mainly found in the nose, respiratory tract, and joints
2. Fibrocartilage is found in the knee, and it is tough and inflexible.
3. Elastic cartilage is found in ear, epiglottis, and larynx. It is the most flexible cartilage.
