The following structures are found in the cortex:
The proximal convoluted tubule (PCT), the distal convoluted tubule (DCT), the glomerulus, the peritubular capillaries, the interlobular artery, and the interlobular vein. The Vasa recta, nephron loop, and collecting duct all belong to the medulla /cortex.
What is a nephron and what does it do?
The nephron, a kidney's functional unit, is the organ's structure responsible for producing urine as waste and surplus substances are eliminated from circulation. Each human kidney contains approximately 1,000,000 nephrons.
The number of nephrons in the "normal" adult human kidney varies greatly, with each kidney containing anywhere between 200,000 and over 1.8 million nephrons, according to autopsy specimens from people belonging to different ethnic groups.
Therefore, When removing waste and extra substances from the blood, the kidney's nephron, a functional unit, actually produces urine.
