D. To pump the blood to different organ of body

Explanation

**Step-by-Step Solution:**

1. **Understanding the Heart's Function**: The primary function of the heart is to pump blood throughout the body. This is essential for delivering oxygen and nutrients to tissues and organs.

2. **Oxygen Delivery**: The heart does not provide oxygen directly; instead, it pumps oxygen-rich blood from the lungs to the rest of the body. The blood carries oxygen to the tissues.

3. **Carbon Dioxide Removal**: The heart also plays a role in collecting carbon dioxide and waste products from the tissues. It pumps deoxygenated blood back to the lungs, where carbon dioxide is expelled and oxygen is absorbed.

4. **Circulation of Blood**: The heart works in conjunction with blood vessels (arteries and veins) to circulate blood. Arteries carry oxygenated blood away from the heart, while veins return deoxygenated blood back to the heart.

5. **Conclusion**: The main work of the heart is to pump blood, which is crucial for the circulation of oxygen, nutrients, and the removal of waste products from the body.

**Final Answer**: The work of the heart is to pump blood to different organs of the body.
