Give values of Alveolar `P_(o_(2))` Venous `P_(co_(2))` and Alveolar `P_(co_(2))`.

Explanation

To answer the question regarding the values of alveolar partial pressure of oxygen (P_O2), venous partial pressure of carbon dioxide (P_CO2), and alveolar partial pressure of carbon dioxide (P_CO2), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Alveolar Partial Pressure of Oxygen (P_O2)**:
- The value of the alveolar partial pressure of oxygen is approximately **104 mmHg**. This indicates the pressure exerted by oxygen in the alveoli of the lungs.

2. **Identify the Venous Partial Pressure of Carbon Dioxide (P_CO2)**:
...
