In the majority of the body all arterioles are afferent as they take blood to the organs they supply. however the tru afferent arterioles are only found in the functional unit of the kidney called the nephron. At the very start of the nephron is a bundle of cappillaries that allows diffusion of the majority of the plasma and contents to diffuse out into another structure called the bormans capsule. From the bowmans capsule the liquid travels through the nephron and any substances that the body still wants to keep diffuse back into the blood. The arteriole that carries blood to the glomerulus is the afferent arteriole and the arteriole that recollects the usefull parts comes from the glomerulus and so is called the efferent arteriole.

Where does the transition from an afferent arteriole to an efferent arteriole occur?

glomerulus. The afferent arteriole leads to a ball of capillaries called a glomerulus which is enclosed in a nephron structure called the glomerular capsule. Blood leaves the glomerulus by way of the efferent arteriole.

What is the Function of efferent arterioles?

The afferent arteriole in a nephron is a larger diameter then the outgoing efferent arteriole and this increase the blood pressure in the glomerulus capillaries resulting in the ultrafiltration of the blood into the Bowman's capsule.

Why is the efferent arteriole smaller than the afferent arteriole?

Efferent arteriole is narrower so as to create hydrostatic pressure for the process of ultrafilteration.
