Verified step by step guidance

Understand the function of each part of the nephron: The nephron is the functional unit of the kidney, and it consists of several parts, each with specific roles in filtering blood and forming urine.

Identify the role of the distal convoluted tubule: The distal convoluted tubule (DCT) is a segment of the nephron that is influenced by hormones such as aldosterone and antidiuretic hormone (ADH). Aldosterone increases sodium reabsorption, while ADH increases water reabsorption.

Consider the function of the glomerulus: The glomerulus is responsible for filtering blood to form a filtrate, but it is not directly influenced by hormones for sodium and water reabsorption.

Evaluate the proximal convoluted tubule: The proximal convoluted tubule (PCT) reabsorbs a significant amount of sodium and water, but this process is not primarily regulated by hormones.

Analyze the loop of Henle: The loop of Henle plays a crucial role in concentrating urine, but it is not the primary site for hormone-regulated sodium and water reabsorption.
