Label the parts in the following diagram.

Afferent arteriole: The afferent arteriole is the arteriole that brings blood to the glomerulus.

Efferent arteriole: The efferent arteriole is the arteriole that carries blood away from the glomerulus.

Bowman's capsule: It performs the first step in the filtration of blood to form urine. It is a sac like structure that encloses the glomerulus which is a bundle of small capillaries.

Glomerulus: The glomerulus increases blood pressure by forming narrow branches of blood vessels that increases surface area for filtration to take place.
