What keeps the alveoli open so that gas exchange can take place? surfactant Why does the surface of the lungs need to be covered with pleura? to enable the lungs to slide past the internal chest wall and diaphragm In humans, the lungs are caused to inflate when the rib muscles and diaphragm contract.
The exchange of gases between the lungs and the blood occurs by the process of diffusion. The type of respiration in which gases are exchanged between the blood and tissue fluid is termed
In an average adult, only about 1/3 of the air actually reaches the alveoli. True or False? False The symptoms of laryngitis include a severe sore throat, high fever, and white patches on the throat. True or False? False You should treat the common cold with antibiotics to shorten the duration of symptoms. True or False? False
False Oxygen in the lungs diffuses from the capillary walls to enter the alveolar walls. True or False? False In an average adult, only about 1/3 of the air actually reaches the alveoli.
The entrance and exit of air into and out of the lungs is called. ventilation. The maximum volume of air that can be moved in plus the maximum volume of air that can be moved out during a single breath is the. vital capacity. When we are relaxed, only a small amount of air moves in and out with each breath.
While sucking it in, your diaphragm contracts and moves DOWN causing the lung volume to INCREASE. This causes the rib cage to move UP and OUT, making your chest larger. A pressurized airplane cabin and an oxygen tent over a patient in a hospital both address the need of a person for oxygen.
