Differentiate between elastic fibres and elastic connective tissue.

Explanation

Some elastic fibres are present. It is found in the skin as the leathery dermis and forms fibrous capsules of organs such as kidneys, bones cartilages, muscles, nerves and joints. Elastic connective tissue contains high proportion of elastic fibres. It allows recoil of tissues following stretching. It maintains the pulsatile flow of blood through the arteries and the passive recoil of lungs following inspiration. It is found in the walls of large arteries, ligaments associated with vertebral column and within the walls of the bronchial tubes.
