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.
<span>there is not adequate empirical support for its effectiveness.
The only thing that they could say 100% true is that during a meditation, average heart rate that people had would be lower compared to normal situation.
But there is still not enough proof to say that this activities could be considered an effective method to cure or maintain hypertension.</span>
Answer:
When purchasing a vehicle it is important to weigh out your decisions prior to your purchase. Safety is very important but it comes with a price. For example if you want airbags and anti-lock brakes you will need to buy a newer vehicle and that will cost you more money. If you want to drive a larger SUV that will protect you more because of its size you will be paying more for gas. It all comes down to a person's views on safety and personal freedoms...and of course cost of the vehicle. For me it will always boil down to cost and efficiency of the vehicle.
