1. Which of the following phases of human lung development is characterized by the formation

of a capillary network around airway passages?
xa xa xa xa xa xa
a. Pseudoglandular
b. Saccular

The canalicular phase follows the pseudoglandular phase, lasting from approximately 17 wee

At 2 years of age, the number of alveoli varies substantially among individuals. After 2 years of

age, males have more alveoli than do females. After alveolar multiplication ends, the alveoli
