The normal range of thrombocytes in the blood is :

Options

A. 1,50,000 - 3,50,000/ `mm^(3)`
B. 1,00,000 - 150,000/`mm^(3)`
C. 15,000 - 35,000 / `mm^3`
D. 3,50,000- 4,50,000 / `mm^3`

Answer

To determine the normal range of thrombocytes (platelets) in the blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Thrombocytes":**
- Thrombocytes are also known as platelets, which are a crucial component of blood that play a significant role in blood clotting.

2. **Identify the Function of Thrombocytes:**
- The primary function of thrombocytes is to facilitate the clotting of blood, which helps in stopping bleeding when injuries occur.

3. **Know the Normal Range:**
- The normal platelet count in the blood typically ranges from 150,000 to 350,000 platelets per cubic millimeter (mm³).

4. **Evaluate the Options:**
- If given multiple-choice options, we would look for the range that matches the normal platelet count of 150,000 to 350,000 mm³.

5. **Identify Abnormal Conditions:**
- If the platelet count exceeds 350,000, it is referred to as thrombocytosis.
- Conversely, if the count falls below 150,000, it is termed thrombocytopenia.

6. **Select the Correct Answer:**
- Based on the information, the correct answer to the question regarding the normal range of thrombocytes in the blood is 150,000 to 350,000 mm³.

### Final Answer:
The normal range of thrombocytes in the blood is **150,000 to 350,000 mm³**.
