Arteries are best defined as the vessels which

Options

A. (a) supply oxygenated blood to the different organs
B. (b) carry blood away from the heart to different organs
C. (c) break up into capillaries which reunite to form a vein
D. (d) carry blood from one visceral organ to another visceral organ

Answer

**Step-by-Step Solution:**

1. **Understanding the Definition of Arteries:**
- Arteries are blood vessels that play a crucial role in the circulatory system. They are primarily responsible for transporting blood away from the heart.

2. **Identifying the Type of Blood Carried:**
- Most arteries carry oxygenated blood, which is rich in oxygen and nutrients. However, there is an exception: the pulmonary artery, which carries deoxygenated blood from the heart to the lungs for oxygenation.

3. **Function of Arteries:**
- The main function of arteries is to supply oxygen-rich blood from the heart to various organs and tissues throughout the body. This ensures that all parts of the body receive the necessary oxygen and nutrients for proper functioning.

4. **Branching of Arteries:**
- As arteries move away from the heart, they branch into smaller vessels known as arterioles, which further divide into capillaries. Capillaries are the smallest blood vessels where the exchange of oxygen, nutrients, and waste products occurs with tissues.

5. **Choosing the Correct Definition:**
- Based on the above points, the most appropriate definition of arteries is that they carry blood away from the heart to different organs. This aligns with option B from the question.

6. **Final Answer:**
- Therefore, the correct answer is option B: "carry blood away from the heart to different organs."
