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.
This language phenomenon is classified as<u> "regionalism".</u>
To comprehend regionalism, we have to know different measurements of the district. Area as a geological unit, is delimited shape one another. District as a social framework, mirrors the connection between various people and gatherings. Locales are a sorted out participation in social, financial, political or military fields. Area goes about as a subject with particular personality, dialect, culture and custom.
Regionalism is a belief system and political development that looks to propel the reasons for districts.
Children who eat an evening meal with their parents tend to get more expressive with their feelings compared to children who eat alone or on the run eat because during meal time, communication with parents is greatly established encouraging the child to speak more and converse.
