Answers
In the given diagram, we have an alveolus with its function shown in brief.
From the first diagram, And the first numbered questions:
[1]
(i) C and D denotes the exchange of gases(Carbon-di-oxide and Oxygen).
C denotes Carbon-di-oxide while D denotes Oxygen.
(ii) Alveolus gets air through the windpipe due to low pressure made in the lungs, because air moves from high pressure to low pressure. From the air, In alveolus, oxygen moves in and absorbs into deoxygenated blood. while pulmonary artery carries the deoxygenated blood and releases the carbon-di-oxide into the alveolus by absorption. While pulmonary artery releases the carbon-di-oxide, on the other side it gets mixed with oxygen. And this mechanism continues...
(iii) B denotes the Carbon-di-oxide being released from the pulmonary artery by absorption, while A denotes oxygen being absorbed into the pulmonary artery.
(iv) Alveolus is a medium where exchange of gases take place, It is very thin and is the end point of all bronchioles.
[2]
(i) Oxygen enters at A into pulmonary artery.
Carbon-di-oxide enters into alveolus at B which a by-product of respiration in cells.
(ii)
- 1 : Pulmonary artery
- 2 : Alveolus (medium)
- 3 : Blood cell
