Question

Every 1000 ml of deoxygenated blood approximately delivers
(A) 4 ml of CO, to the alveoli
(B) 50 ml of CO2 to the tissue
(C) 40 ml of CO2 to the alveoli
(D) 200 ml of CO, to the atmosphere​

Answer 1

Answer:

every 100mL of deoxygenated blood delivers 4 mL of CO2 to alveoli so 1000 mL will deliver 40 mL

Answer 2

1000 mL of deoxygenated blood will approximately deliver 40 mL CO₂ to the alveoli

• In our bodies, the blood is responsible for the exchange of gases between organs/tissues and the lungs. CO₂ gets released out of the body while O₂ is inhaled to supply organs with fresh O₂.
• Each 100 mL of deoxygenated blood carries about 4 mL CO₂, thus if we apply the unitary method, every 1000 mL of deoxygenated blood will deliver 40mL of CO₂ to the alveoli.

Thus, Every 1000 ml of deoxygenated blood approximately delivers (Option C) 40 ml of CO₂ to the alveoli.
