Find out the amount of `O_(2)` which is delivered by 100 ml of oxygenated blood to the tissue under normal physiological conditions -

Options

A. 4 ml
B. 20 ml
C. 5 ml
D. 25 ml

Answer

To find out the amount of \( O_2 \) delivered by 100 ml of oxygenated blood to the tissues under normal physiological conditions, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: We need to determine how much oxygen is delivered from 100 ml of oxygenated blood to the tissues. Under normal physiological conditions, blood carries oxygen to the tissues.

2. **Identify the Amount of Oxygen in Blood**: It is generally accepted that about 20 ml of oxygen is dissolved in 100 ml of oxygenated blood. However, this can vary based on physiological conditions.

3. **Determine the Amount Delivered to Tissues**: Under normal physiological conditions, approximately 4-5 ml of oxygen is typically delivered to the tissues from 100 ml of oxygenated blood. For this calculation, we will use the average value of 4 ml for simplicity.

4. **Calculate the Amount of Oxygen Delivered**:
- If 100 ml of oxygenated blood delivers about 4 ml of oxygen to the tissues, then the amount of \( O_2 \) delivered by 100 ml of oxygenated blood is:
\[ \text{Amount of } O_2 \text{ delivered} = 4 \text{ ml} \]

5. **Conclusion**: Therefore, the amount of \( O_2 \) delivered by 100 ml of oxygenated blood to the tissues under normal physiological conditions is 4 ml.

### Final Answer:
The amount of \( O_2 \) delivered by 100 ml of oxygenated blood to the tissues is **4 ml**.
