Explanation:
Detailed explanation-1: -Elastic fibres are essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils. They endow connective tissues such as blood vessels, lungs and skin with the critical properties of elasticity and resilience.
Detailed explanation-2: -Elastin makes tissues elastic, so that the tissue will recoil after stretch. Elastic fibres are 5 times more extensible than an elastic band! Mixing up collagen (less extensible) and elastin, prevents overstretch.
