Cartilage: The intercellular material of cartilage is solid and pliable and resists compression. Cells of cartilage (chondrocytes) are enclosed in small cavities within the matrix secreted by them. Cartilage is present in the tip of nose, outer ear joints, ear pinna, between adjacent bones of the vertebral column, limbs, and hands-on adults.
Bones: Bones have a hard and non-pliable ground substance rich in calcium salts and collagen fibres. Bones support and protect softer tissues and organs. Osteoblasts are present in the spaces called lacunae.
Blood: It is the fluid connective tissue. It contains RBCs, WBCs, and platelets. It functions as a transport medium for nutrients, wastes, and respiratory gases.
