The gland which acts to resist stress

Options

A. Adrenal
B. Parathyroid
C. Pineal
D. Thyroid

Explanation

**Step-by-Step Solution:**

1. **Identify the Gland Related to Stress Response:**
- The question asks for the gland that acts to resist stress. Among the options provided (Adrenal, Parathyroid, Pineal, Thyroid), we need to determine which gland is primarily involved in the stress response.

2. **Understand the Function of the Adrenal Gland:**
- The adrenal gland is known for its role in the body's response to stress. It produces hormones that help regulate metabolism, immune response, and blood pressure, especially during stressful situations.

3. **Recognize the Hormones Produced by the Adrenal Gland:**
- The adrenal gland secretes several hormones, including glucocorticoids (like cortisol), which are crucial in managing stress. These hormones help to increase glucose availability in the blood, providing energy to deal with stress.

4. **Evaluate Other Glands:**
- Parathyroid glands regulate calcium levels in the blood and are not directly involved in stress response.
- The pineal gland produces melatonin, which regulates sleep-wake cycles and is not related to stress.
- The thyroid gland regulates metabolism but does not specifically address stress.

5. **Conclude the Answer:**
- Based on the functions of the glands discussed, the adrenal gland is the correct answer as it plays a significant role in resisting stress through the secretion of glucocorticoids.

**Final Answer:**
The gland which acts to resist stress is the **Adrenal Gland**.
