Dorsal aorta

Vedclass · Answer

(B) The $Dorsal$ $aorta$ is a major artery that carries oxygenated blood from the heart to the rest of the body. Arteries,especially large ones like the $Dorsal$ $aorta$,possess a thick tunica media containing abundant elastic fibers. These elastic fibers allow the vessel to expand and recoil in response to the pressure generated by the heart's ventricular contraction,which helps maintain continuous blood flow. Therefore,the $Dorsal$ $aorta$ has a highly elastic wall compared to veins (like $Precaval$ and $Post$ $caval$) or smaller vessels like $Arterioles$.

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

Which one of the following has an elastic wall?
