Name the organ of the body from which blood freshly enriched with oxygen goes into the heart .

Answer

To answer the question, "Name the organ of the body from which blood freshly enriched with oxygen goes into the heart," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of the Lungs**: The lungs are the organs responsible for gas exchange in the body. They take in oxygen from the air and transfer it to the blood while removing carbon dioxide from the blood.

2. **Identify the Process of Oxygenation**: When deoxygenated blood (blood low in oxygen) reaches the lungs, it releases carbon dioxide and absorbs oxygen. This process is called respiration.

3. **Recognize the Path of Blood Flow**: After the blood is oxygenated in the lungs, it is carried back to the heart. The oxygen-rich blood travels through the pulmonary veins.

4. **Determine the Destination of Oxygenated Blood**: The oxygenated blood from the lungs enters the left atrium of the heart. From there, it is pumped into the left ventricle and then distributed to the rest of the body.

5. **Conclude the Answer**: Therefore, the organ from which blood freshly enriched with oxygen goes into the heart is the **lungs**.

### Final Answer:
The organ of the body from which blood freshly enriched with oxygen goes into the heart is the **lungs**.
