Exchange of Gases in the Lungs
At the lungs exchange of carbon dioxide and oxygen takes place in alveoli. This process takes place by the process of diffusion. In lungs pressure of carbon dioxide is greater than pressure of carbon dioxide in air. Therefore carbon dioxide diffuses out of the alveoli. The oxygen first diffuses in fluid present in the walls of alveoli and then into the blood.
Note: As a result, having spent a decent amount and time for training, a graduate of such a university does not receive the necessary knowledge . Therefore, upon admission, it is important to pay attention to state accreditation and the license of the educational institution in question. Too low payment for the services provided and the location of the school building should also alert future students and their parents. On the pros and cons of obtaining a higher education you can argue endlessly. As a result, everyone makes the final decision himself, depending on the plans for the future. If there is a goal to make a career in a Russian or a foreign large company, to master a serious profession or to obtain a scientific degree, obtaining a university diploma will be a necessary step on the way to this goal. Modern realities, however, are such that even if there is a great desire, not everyone now has the opportunity to receive this kind of education.
