Thrombocytes have a life of

Options

A. 3-4 weeks
B. 4-5 weeks
C. 4-5 days
D. 4-5 hours

Answer

To determine the lifespan of thrombocytes (platelets), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Thrombocytes**: Thrombocytes, commonly known as platelets, are small cell fragments in the blood that play a crucial role in the process of blood clotting.

2. **Function of Thrombocytes**: Their primary function is to prevent excessive bleeding by forming clots at the site of injury. When a blood vessel is damaged, platelets aggregate at the injury site and release chemicals that help in the clotting process.

3. **Lifespan of Thrombocytes**: The question asks for the lifespan of thrombocytes. Based on biological studies, it is known that the average lifespan of platelets is relatively short.

4. **Evaluating the Options**: The options given are:
- 3-4 weeks
- 4-5 weeks
- 4-5 days
- 4-5 hours

5. **Identifying the Correct Answer**: Research indicates that thrombocytes typically have a lifespan of about 4 to 5 days. Therefore, the correct answer is **4-5 days**.

### Final Answer:
Thrombocytes have a life of **4-5 days**.
