What is significance of respiratory pigment in respiration ?

Explanation

### Step-by-Step Solution:

1. **Identify the Respiratory Pigment**: The primary respiratory pigment in humans is hemoglobin, which is found in red blood cells (erythrocytes).

2. **Function of Hemoglobin**: Hemoglobin plays a crucial role in respiration by transporting oxygen from the lungs to the body tissues.

3. **Oxygen Transport**: When we inhale, oxygen enters the lungs and diffuses into the blood, where it binds to hemoglobin. This process allows for efficient oxygen delivery to cells throughout the body.
