B Name the following

1 photosynthesis

2 Autotrophic organism

3 Chlorophyll

6 WBC cell

Answer 2

Answer:

4) the alveoli provides the surface where the exchange of gases can take place....The walls of the alveoli is supported by a extensive network of blood vessels.So lungs maxsimise the area for gaseous exchange through the presence of large number of alveoli which are richly supplied with blood.
