Question 18 of 34
How do the structures of alveoli and capillaries support the function of gas
exchange?
Bronchiole
Alveoll
Smal blood
vessels (capillarles)
A. The shapes of the alveoli and the capillaries allow for a large
surface area for gas exchange.
B. Pores in the membranes allow oxygen to move out of the alveoli's
cells and carbon dioxide to move into the cells.
C. The shapes of the alveoli and the capillaries slow blood flow,
allowing for more time for gas exchange.
D. The membranes have proteins that transport carbon dioxide and
oxygen against the concentration gradients.

The structure of alveoli and capillaries supports the function of gas exchange by forming the pores in the membranes allowing oxygen to move out of the alveoli's cells and carbon dioxide to move into the cells. Thus, the correct option is B.

What is Gas exchange?

The Gas exchange may be characterized as the biological approach through which specific gases are migrated across cell membranes to either enter or exit the blood.

During the process of gas exchange, oxygen is consistently needed for cells to perform cellular respiration, while carbon dioxide is eliminated as a waste product.

This entry and exit of oxygen and carbon dioxide are mediated by the pores which are present in the alveoli and capillaries of the heart.

Therefore, the correct option for this question is B.
