The life span of thrombocytes is

Options

A. A) 4 to 5 weeks
B. B) 3 to 4 weeks
C. C) 3 to 7 days
D. D) none of these

Explanation

**Step-by-Step Solution:**

1. **Understanding Thrombocytes**: Thrombocytes, also known as platelets, are a crucial component of blood. They play a significant role in the process of blood clotting.

2. **Formation of Thrombocytes**: Thrombocytes are produced in the bone marrow, which is a spongy tissue found within bones.

3. **Function of Thrombocytes**: The primary function of thrombocytes is to aid in the clotting of blood, especially when there is a wound or injury.

4. **Lifespan of Thrombocytes**: The lifespan of thrombocytes is approximately 3 to 7 days.

5. **Average Circulation**: On average, circulating platelets can survive for about 8 to 9 days, but they are typically destroyed by the spleen and liver after around 7 days.

6. **Destruction Process**: The old thrombocytes are removed from circulation through a process called phagocytosis, which is carried out by the spleen and liver.

7. **Conclusion**: Based on the lifespan information, the correct answer to the question regarding the lifespan of thrombocytes is 3 to 7 days.

**Final Answer**: The lifespan of thrombocytes is approximately 3 to 7 days.
