The circulation which provides nitrients, `O_(2)` and essential substances to the tissue and takes `CO_(2)` and other harmful substances away for elimination is

Options

A. Systemic circulation
B. Pulmonary circulation
C. Double circulation
D. Ststematic circulation

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question:** The question asks about the type of circulation that delivers nutrients and oxygen (O2) to tissues and removes carbon dioxide (CO2) and other harmful substances for elimination.

2. **Identifying Circulatory Systems:** There are two main types of circulation in the human body:
- **Pulmonary Circulation:** This involves the movement of blood between the heart and the lungs. It is responsible for oxygenating the blood by exchanging CO2 for O2 in the lungs.
- **Systemic Circulation:** This involves the movement of blood between the heart and the rest of the body. It delivers oxygenated blood and nutrients to tissues and returns deoxygenated blood and waste products back to the heart.

3. **Analyzing the Functions of Each Circulation:**
- **Pulmonary Circulation:** Primarily focuses on gas exchange (O2 and CO2) in the lungs, not directly involved in delivering nutrients to tissues.
- **Systemic Circulation:** Delivers oxygen and nutrients to body tissues and removes CO2 and waste products, making it essential for tissue health.

4. **Conclusion:** Based on the functions described, the circulation that provides nutrients and O2 to tissues while removing CO2 and other harmful substances is **Systemic Circulation**.

5. **Final Answer:** The correct option is **Systemic Circulation**.
