Tunica media

Vedclass · Answer

(B) The wall of blood vessels consists of three layers: $Tunica$ $intima$ (inner layer),$Tunica$ $media$ (middle layer),and $Tunica$ $externa$ (outer layer).In arteries,the $Tunica$ $media$ is significantly thicker and more muscular compared to veins.This increased thickness of the $Tunica$ $media$ provides structural support to withstand high blood pressure and results in a narrower lumen in arteries compared to veins.

Column-$A$	Column-$B$
$(1)$ Aorta	$(A)$ Carries deoxygenated blood from the heart to lungs
$(2)$ Capillaries	$(B)$ Largest blood vessel
$(3)$ Pulmonary artery	$(C)$ Tiny blood vessels where exchange of gases occurs
$(4)$ Veins	$(D)$ Blood vessels that carry blood back to heart

This layer is more thickened in an artery than in a vein,so the lumen is small in an artery.
