Answer:
Surfactant increases airflow. It has this effect on airflow because it reduces resistance to lung inflation. Airflow increased as predicted.
Explanation:
Pulmonary surfactant is a complex mixture of lipids and proteins secreted by the Type II alveolar cells. The major component of surfactant, dipalmitoyl-phosphatidylcholine (DPPC), is an amphiphatic phospholipid. The main function of the pulmonary surfactant is to reduce the surface tension at the air/liquid interface in the lungs by forming lining layer between the aqueous airway liquid and the inspired air. prevents alveolar and airway collapse at end-expiration and thus allows cyclic ventilation of the lungs. It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. By lowering alveolar surface tension, pulmonary surfactant provides two important benefits:
(1) it increases pulmonary compliance, reducing the work of inflating the lungs; and
(2) it reduces the lungs’ tendency to recoil, so they do not collapse as readily.

President Obama ordered bombing raids against a radical Sunni group that had seized large parts of the territory in Syria and Iraq.

In contrast to the Shiah, who are considered to be a minority denomination within Islam, Sunni Muslims consider their sect to be the more mainstream and orthodox branch of Islam.

An acquisition that results in expansion indicates that expectations were not met.
An acquisition that ends up in enlargement indicates that the expectations weren't met. The business economic cycle stage called expansion happens once real gross the domestic product (GDP) will increase for 2 or additional consecutive quarters, going from a low point to a high point.
Example of expansion- There are two main sources of economic expansion which are growth in the size of the workforce and growth in the productivity of that workforce. The effects of economic expansion are rise in GDP, increase in per capita income and decrease in unemployment.
