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.
Answer:
The Central American nation that is a democratic republic, with a population between four and five million, and whose territory is slighty smaller than the state of West Virginia is Costa Rica.
Explanation:
Costa Rica is a country in Central America. The country borders Nicaragua in the north and Panama in the south. To the east of the country is the Caribbean Sea, and to the west is the Pacific Ocean. Costa Rica has just over 4.8 million inhabitants, and an area of 51,100 km².
Today, the country has a stable democracy and is the oldest democracy in Latin America. It has always been among the Latin American countries with the highest HDI, and is ranked 62nd in the world. The crime rate is relatively low, the country is considered one of the safest in Latin America.
