Loose connective tissue (which includes areolar tissue, reticular tissue, and adipose tissue) holds organs in place and attaches epithelial tissue to other underlying tissues. It also surrounds the blood vessels and nerves. Cells called fibroblasts are widely dispersed in this tissue. Dense regular tissue includes tendons and ligaments. Tendon connects skeletal muscle with a bone. Ligaments attach one bone to another.
Dense irregular tissue includes skin. Specialized connective tissue includes cartilage, bones and blood. Cartilage is a rubbery tissue made by cells called chondroblasts. It does not have any blood vessels within it so healing is not easy if it is damaged and may not occur at all if the damage is extensive enough. Bone is a rigid organ that constitutes part of the vertebral skeleton. It support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. Blood delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away.
