Which of the following is called emergency gland of the body?

Options

A. Testis
B. Adrenal cortex
C. Thymus
D. Pituitary

Explanation

To answer the question "Which of the following is called the emergency gland of the body?", we can follow these steps:

### Step 1: Identify the Gland
The question refers to a gland in the body that is associated with emergency responses. The gland known for this function is the adrenal gland.

**Hint:** Think about which gland is involved in the body's fight-or-flight response.

### Step 2: Understand the Function of the Adrenal Gland
The adrenal gland secretes hormones that help the body respond to stress. The primary hormone released during emergencies is adrenaline (also known as epinephrine).

**Hint:** Recall what hormones are released during stressful situations.

### Step 3: Recognize the Role of Adrenaline
Adrenaline prepares the body for emergency situations by increasing heart rate, breathing rate, blood pressure, and blood sugar levels. This helps provide the energy needed for a quick response.

**Hint:** Consider how the body physically reacts when faced with danger or stress.

### Step 4: Differentiate Between Parts of the Adrenal Gland
The adrenal gland has two main parts: the adrenal cortex and the adrenal medulla. While both parts secrete hormones, it is the adrenal medulla that primarily secretes adrenaline, making it crucial for emergency responses.

**Hint:** Remember the distinction between the cortex and medulla in the adrenal gland.

### Step 5: Conclude the Answer
Based on the information gathered, we can conclude that the adrenal gland, specifically the adrenal medulla, is referred to as the emergency gland of the body due to its role in releasing adrenaline.

**Hint:** Think about the overall purpose of the adrenal gland in emergency situations.

### Final Answer
The emergency gland of the body is the adrenal gland (specifically, the adrenal medulla).
