Answer to Question 1

ANS: A
The respiratory system is a unique organ in that it receives a double blood supply: one from the left ventricle and one from the right ventricle.

Answer to Question 2

ANS: B
With a more compliant thorax, the resultant balance of these static forces in the infant favors a reduced FRC and total lung capacity (TLC). Proportionately lower lung volumes in the infant can lead to early airway closure, atelectasis, ventilation/perfusion mismatch, shunting, and re-sultant hypoxemia.
