Deoxygenated blood is transported from the tissues to the heart through

Options

A. arteries
B. veins
C. lymph
D. ventricles

Answer

### Step-by-Step Solution:

1. **Understanding Blood Circulation**: Blood circulates through the body in two main pathways: the systemic circulation and the pulmonary circulation. In systemic circulation, oxygenated blood is delivered to the tissues, while deoxygenated blood is returned to the heart.

2. **Identifying Blood Vessels**:
- **Arteries**: These are blood vessels that carry oxygenated blood away from the heart to the tissues. They do not transport deoxygenated blood.
- **Veins**: These are blood vessels that carry deoxygenated blood from the tissues back to the heart. This is the primary focus of the question.

3. **Excluding Incorrect Options**:
- **Lymph**: This is a fluid that is part of the lymphatic system and does not transport blood. Therefore, it is not the correct answer.
- **Ventricles**: These are chambers of the heart that pump blood but do not transport blood from the tissues to the heart. They are involved in the pumping action of the heart.

4. **Conclusion**: The correct answer to the question is that deoxygenated blood is transported from the tissues to the heart through **veins**.

### Final Answer:
Deoxygenated blood is transported from the tissues to the heart through **veins**.
