Find out the amount of `CO_(2)` which is delivered by every 100 ml of deoxygenated blood to the alveoli

Options

A. 20 ml
B. 4 ml
C. 5 ml
D. 50 ml

Answer

To find out the amount of CO₂ delivered by every 100 ml of deoxygenated blood to the alveoli, we can follow these steps:

### Step 1: Understand the Composition of Deoxygenated Blood
Deoxygenated blood contains carbon dioxide (CO₂) that has been produced by the tissues during cellular respiration. This CO₂ is transported in the blood in three forms: dissolved in plasma, as bicarbonate ions (HCO₃⁻), and bound to hemoglobin as carbaminohemoglobin.

### Step 2: Know the Average CO₂ Content
On average, deoxygenated blood carries about 52 ml of CO₂ per 100 ml of blood. This is the total amount of CO₂ that can be delivered to the alveoli.

### Step 3: Calculate the Amount of CO₂ Delivered
Since we are considering 100 ml of deoxygenated blood, we can directly state that:
- Amount of CO₂ delivered to the alveoli = 52 ml per 100 ml of deoxygenated blood.

### Step 4: Conclusion
Therefore, the amount of CO₂ delivered by every 100 ml of deoxygenated blood to the alveoli is **52 ml**.
