Distal Convoluted Tubule (DCT)

Adjusts salt, pH, water balance

Proximal Convoluted Tubule (PCT)

Reabsorbs water, glucose, ions

Renal Artery

Brings unfiltered blood to kidney

Capillaries

Reabsorb useful substances; secrete wastes

Afferent Arteriole

A small blood vessel that brings blood into the glomerulus, which is part of the nephron in the kidney

Loop of Henle

Creates salt gradient; concentrates urine

Efferent Arteriole

A small blood vessel that carries blood away from the glomerulus after filtration has occurred.

Medulla

The medulla is the inner region of the kidney that contains structures such as the loops of Henle and collecting ducts, and is responsible for concentrating urine.

Renal Vein

The renal vein is a blood vessel that carries filtered, deoxygenated blood away from the kidney and into the inferior vena cava.

Renal Pelvis

The renal pelvis is a funnel-shaped cavity in the kidney that collects urine from the medulla and directs it into the ureter

Nephron

nephron is the microscopic functional unit of the kidney that filters blood, reabsorbs useful substances, and removes waste to form urine.

Cortex

Outer layer of kidney responsible for filtration of blood
