Aldosterone stimulate the reabosorption of `"_____" and"______"` ion in `"_________"` tubule

Options

A. `Na^(+), K^(+),` distal part
B. `Na ^(+), H_(2)O,` distal part
C. Glucose, `H_(2)O,` distal part
D. Glucose, `H_(2)O,` initial part

Answer

To answer the question, "Aldosterone stimulates the reabsorption of '_____' and '______' ions in '________' tubule," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Aldosterone**:
- Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in regulating sodium and potassium levels in the body.

2. **Identifying the Function of Aldosterone**:
- The primary function of aldosterone is to increase the reabsorption of sodium ions (Na⁺) in the kidneys, which helps to retain water and increase blood volume and blood pressure.

3. **Considering Potassium**:
- While aldosterone promotes the reabsorption of sodium, it also promotes the excretion of potassium ions (K⁺). Therefore, it is important to note that aldosterone stimulates the reabsorption of sodium while facilitating the loss of potassium.

4. **Locating the Site of Action**:
- Aldosterone acts mainly on the distal convoluted tubule and the collecting ducts of the nephron in the kidneys.

5. **Filling in the Blanks**:
- Based on the above information, we can fill in the blanks:
- Aldosterone stimulates the reabsorption of **sodium** and **water** ions in the **distal convoluted** tubule.

### Final Answer:
Aldosterone stimulates the reabsorption of **sodium** and **water** ions in the **distal convoluted** tubule.
