Solution

The part of the nephron where the ultrafiltration process takes place is the Malpighian corpuscle (also known as the glomerulus within Bowman's capsule). Here's a step-by-step explanation:

  1. Blood enters the kidney through the renal artery, which splits into many arterioles, each leading to a nephron.

  2. Each nephron begins with a structure called the Malpighian corpuscle, which is composed of the Bowman's capsule and the glomerulus.

  3. The glomerulus is a network of capillaries that performs the first step in filtering blood to form urine. This is where ultrafiltration occurs.

  4. Ultrafiltration is the process by which small molecules such as water, glucose, amino acids, and urea pass from the blood in the glomerulus into the Bowman's capsule. This forms the glomerular filtrate.

  5. The filtrate then passes through the rest of the nephron (the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule), where selective reabsorption occurs.

  6. The remaining fluid, now called urine, passes into the collecting duct and then out of the kidney via the ureter.

So, the correct answer is A: Malpighian corpuscle.
