Aveolar macrophages work to break up surfactanct in the aveoli which exists to decrease surface tension in the lungs. If there is a disorder where the macrophage does not function correctly, such as in PAP, the surfactant will not be broken up and decreased ventilation will occur resulting in less oxygen delivery.

Function of alveolar ducts?
Trap air in lungs (act as air pockets 4 gaseous exchange).
What is pulmonary alveolar proteinosis?
Pulmonary alveolar proteinosis (PAP) is a rare disease of the lungs.
What is an alveolar dead space?
An alveolar dead space is the volume of air in the alveoli of the lungs which does not partake in gas exchange.
What is function of ventilation?
The main function of the pulmonary vein is to carry oxygenated blood from the lungs to the left atrium. Then it is transferred to the aorta, which takes the blood to the head and arms.
Site of alveolar-capillary oxygen exchange?
Within the lungs.
What is the function of the gingiva?
Cover of alveolar bone
What is a conducting structure in the Lungs?
Respiratory bronchioles, alveolar ducts, and alveoli.
What kind of epithelial tissue is in the alveolar sacs of the lungs?
Simple Squamous
Where do blood cells pick up oxygen?
In the lungs, in the alveolar capillaries
What are the most numerous cells in the lungs?
type 1 alveolar cells
What is the total alveolar surface area in the lungs of human beings?
100m2
What is the volume of gas that reaches the respiratory zone of the lungs called?
alveolar ventilation
