PATHOLOGY

Detailed explanation-1: -The efferent arterioles are blood vessels that are part of the urinary tract of organisms. Efferent (from Latin ex + ferre) means “outgoing", in this case meaning carrying blood out away from the glomerulus.

Detailed explanation-2: -1) Afferent arteries bring deoxygenated blood from the lungs to the heart while efferent arteries return oxygenated blood from the heart to the lungs.

Detailed explanation-3: -Efferent vessel: A vessel that carries blood away from the heart. Hence, an efferent vessel is an artery or an arteriole (a little artery).

Detailed explanation-4: -However, efferent arterioles that are located above the corticomedullary border travel downward into the medulla. They further divide into vasa recta which surround the Loop of Henle. The purpose of these vessels is to supply capillaries located in the medulla.
