Name the following:
The respiratory pigment present in erythrocytes.

Explanation

**Step-by-Step Solution:**

1. **Identify Erythrocytes**: Erythrocytes are commonly known as red blood cells (RBCs). They are a crucial component of blood responsible for transporting gases, nutrients, and other substances throughout the body.

2. **Function of Erythrocytes**: The primary function of erythrocytes is to transport oxygen from the lungs to the tissues and carry carbon dioxide from the tissues back to the lungs. This gas exchange is vital for respiration and energy production in cells.

3. **Respiratory Pigment**: Within the erythrocytes, there is a specific pigment that plays a key role in the transport of oxygen and carbon dioxide. This pigment is essential for the respiratory process.
