How does the exchange of carbon dioxide for oxygen take place in the lungs?

Answer 1

The exchange of oxygen and carbon dioxide takes place in between the alveoli and capillaries. Oxygen moves through the cell membrane of the capillaries of the alveoli and then into the blood. Then oxygen is picked up by hemoglobin, and carried to all the body cells. At the same time, waste(carbon dioxide) leaves the body by exhaling --- @luvzbieber

Answer 2

The exchange procedure occurs in the lungs, in the respiratory system. The procedure occurs by diffusion. Carbon dioxide diffuses from the blood to the alveoli and oxygen diffuses in the reverse procedure.

Answer 3

The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. This barrier between air and blood averages about 1 micron (1/10,000 of a centimeter) in thickness. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body
Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide
To support the exchange of oxygen and carbon dioxide, about 6 to 10 liters of air per minute are brought in and out of the lungs, and about three tenths of a liter of oxygen is transferred from the alveoli to the blood each minute, even when the person is at rest. At the same time, a similar volume of carbon dioxide moves from the blood to the alveoli and is exhaled. During exercise, it is possible to breathe in and out more than 100 liters of air per minute and extract 3 liters of oxygen from this air per minute. The rate at which oxygen is used by the body is one measure of the rate of energy expended by the body. Breathing in and out is accomplished by respiratory muscles

Answer 4

Gas exchange in the lungs occurs in the alveoli (tiny sacs at the end of the lungs). Carbon dioxide moves across from the capillaries (small blood vessels wrapped around the alveoli) into the alveoli and oxygen moves across from the alveoli to the capillaries through the process of diffusion.

Diffusion is the movement of a substance from a high concentration to a low concentration.

Answer 5

the exchange of oxygen and carbon dioxidetakes place in the alveoi, the lungs. this takes about 5 seconds.

Answer 6

i have no idea that's why i asked you tell me!!

Answer 7

the system of highly qualified experience of extimulated gravital has potential which is know to humans

Answer 8

it brings in the oxygen and the CO2 (carbon dioxide) comes out because you do not need that.

Answer 9

lungs
