Which part of nephron is effected by aldosterone ?

Options

A. P.C.T.
B. Late part of C.T.
C. D.C.T.
D. Duct of bellini

Answer

**Step-by-Step Solution:**

1. **Understanding the Nephron Structure**: The nephron is the functional unit of the kidney and consists of several parts, including the proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and collecting duct.

2. **Role of Aldosterone**: Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in regulating sodium and potassium levels in the body. It promotes sodium reabsorption and potassium excretion in the kidneys.

3. **Identifying the Affected Part**: Among the various parts of the nephron, the distal convoluted tubule (DCT) is primarily affected by aldosterone. This hormone acts on the DCT to increase sodium reabsorption, which in turn helps in water retention and increases blood volume.

4. **Conclusion**: Therefore, the part of the nephron that is affected by aldosterone is the distal convoluted tubule (DCT).

**Final Answer**: The part of the nephron affected by aldosterone is the Distal Convoluted Tubule (DCT).
