Match the source gland with respective hormone as well as the function correctly .

Options

A. `{:("Source gland","Hormone","Function"),("Anterior pituitary","Oxytocin","Contraction of uterus muscles during child birth"):}`
B. `{:("Source gland","Hormone","Function"),("Posterior pituitary","Vasopressin","Stimulates reabsorption of water in the distal tubules in the nephron"):}`
C. `{:("Source gland","Hormone","Function"),("Corpus luteum","Estrogen","Supports pregnancy"):}`
D. `{:("Source gland","Hormone","Function"),("Thyroid","Thyroxine","Regulates blood calcium level"):}`

Answer

To solve the question of matching the source gland with the respective hormone and its function, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Glands and Hormones**:
- We have two glands mentioned: Anterior Pituitary and Posterior Pituitary.
- We also have the corpus luteum and thyroid gland to consider.

2. **Match the Hormones with Their Source Glands**:
- **Anterior Pituitary**: It does not produce oxytocin. Oxytocin is produced by the posterior pituitary.
- **Posterior Pituitary**: Produces vasopressin (also known as ADH - Antidiuretic Hormone), which is responsible for water reabsorption in the kidneys.

3. **Consider the Other Glands**:
- **Corpus Luteum**: After ovulation, the remaining Graafian follicles form the corpus luteum, which produces progesterone.
- **Thyroid Gland**: Produces thyroxine (T4), which regulates the basal metabolic rate.

4. **Check the Functions of the Hormones**:
- **Vasopressin (ADH)**: Responsible for water reabsorption.
- **Thyroxine (T4)**: Regulates the basal metabolic rate.
- **Progesterone**: Involved in regulating the menstrual cycle and maintaining pregnancy.

5. **Final Matching**:
- Anterior Pituitary: Incorrectly matched with oxytocin.
- Posterior Pituitary: Correctly matched with vasopressin (ADH) and its function (water reabsorption).
- Corpus Luteum: Correctly matched with progesterone.
- Thyroid: Correctly matched with thyroxine and its function (regulating metabolic rate).

6. **Conclusion**: The correct option is the one that matches the posterior pituitary with vasopressin and its function of water reabsorption.
