The term gigahertz, or GHz, refers to the operating speed of a central processing unit; hertz defines the clock rate, or cycles per second, of the CPU. 1 GHz is equivalent to one billion hertz. Businesses can increase the frequency of a processor to improve the speed of a computer through a process known as overclocking..
Purpose. Surfactant reduces the surface tension of fluid in the lungs and helps make the small air sacs in the lungs (alveoli) more stable. This keeps them from collapsing when an individual exhales.or example, if a drop of detergent is added to a drop of water, the detergent reduces the surface tension and the drop of water flattens out. In the lungs, surfactant reduces the surface tension and helps to maximize the surface area available for gas exchange.
Surfactant is a product which is secreted by the lungs. Its purpose is to reduce the lungs surface tension. Without surfactant the moist surfaces of the lungs would have such â¦ a high surface tension that the smaller alveoli would collapse. 3 people found this useful.ithout surfactant, the wet surfaces of the alveoli in your lungs would stick together and your lungs would not be able to expand-so, you would not be able to breath. The alveoli are the tiny sacs in your lungs where oxygen is captured from inhaled air and absorbed into your bloodstream.
