The volume occupied by formed elements in the blood is

Options

A. 0.3
B. 0.45
C. 0.55
D. 0.75

Answer

To solve the question regarding the volume occupied by formed elements in the blood, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Components of Blood**: Blood is made up of two main components: formed elements and plasma. The formed elements include red blood cells (RBCs), white blood cells (WBCs), and platelets.

2. **Identify the Volume Percentage of Formed Elements**: The formed elements (RBCs, WBCs, and platelets) constitute approximately 40% to 45% of the total blood volume.

3. **Differentiate Between Formed Elements and Plasma**: The remaining volume, which is about 55% of the total blood volume, is occupied by plasma, a liquid component that carries cells, nutrients, and waste products.

4. **Conclusion**: Based on the information, the volume occupied by formed elements in the blood is between 40% and 45%. Therefore, the answer to the question is that the volume occupied by formed elements in the blood is approximately 40% to 45%.

5. **Select the Correct Option**: If the question provides multiple-choice options, the correct answer would be the one that indicates the volume of formed elements as 40% to 45%.

### Final Answer:
The volume occupied by formed elements in the blood is approximately 40% to 45%.
