Question
Chapter 24, Problem 13RFT
Summary Introduction
Introduction:
Pulmonary surfactant refers to the mixture of the lipids and proteins that are released into the alveolar gaps in the epithelial cells (type II). It is commonly found in the fluid lining of the lungs.

The alveolar walls are composed of two types of cells type I
and type II pneumocytes. The function of type II cells is to
O increase surface tension
O secrete surfactant
O decrease surface tension
O trap dust and other debris
O b) and c)
O b) and d)
The function of type I alveolar cells is to (a) produce surfactant, (b) propel sheets of mucus, (c) remove dust particles through phagocytosis, (d) allow rapid diffusion of respiratory gases.
Air moves into the alveoli as a result of the:
(A)Decreased pressure in the chest cavity
(B) Relaxation of the diaphragm
(C) Rising pressure in the alveoli
(D) Rising pressure in the chest cavity
