Loop Of Henle

The portion of the renal tubule that curves back toward the renal corpuscle and twists again to become the distal convoluted tubule.

Renal Corpuscle

The initial filtering component of the nephron in the kidney, where blood plasma is filtered through the capillary walls of the glomerulus into the Bowman's capsule.
