Question

What is the cause for the movement of oxygen
through the alveolar blood capillaries of lungs ?
(a) Difference in the O₂ tension and partial
pressure of these chambers
(b) Partial pressure of CO₂
(c) Union of O₂ with haemoglobin
(d) All of the above

Answer 1

Answer:

difference in the O2 tension and partial pressure of these chambers

Answer 2

The correct answer is (A).

Explanation:

• Difference in the O2 tension and Partial pressure of these chambers causes the movement of oxygen through the alveolar blood capillaries of lungs.
• Tiny blood vessels are seen around the Alveoli which is known as Capillaries.
• The oxygen which is inhaled moves from the alveoli goes to the blood in the Capillaries.

• The carbon dioxide from the blood which is present in the capillaries and goes to the air in the alveoli.
