Question

under normal condition,2L of deoxygenated blood approximately delivers how much amount of co2 to alveoli?
a) 80ml
b) 40 ml
c) 100 ml
d) 50 ml
​

Answer 1

Approximately 4 mL of CO₂ is delivered to the alveoli every 100 mL of deoxygenated blood.

• Hence, every 1000 mL or 1 liter of deoxygenated blood would deliver 40 mL of CO₂ to the alveoli.
• So, every 2000 mL or 2 liters of deoxygenated blood would deliver 80 mL of CO₂ to the alveoli.

Hence, the correct option is a) 80 mL.
