Which system is used in the exchange of gases between blood and air?
The respiratory system
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
Why oxygen and carbon dioxide are exchanged between the lungs and the bloodstream?
The partial pressures of oxygen and carbon dioxide change as blood moves through the body. In short, the change in partial pressure from the alveoli to the capillaries drives the oxygen into the tissues and the carbon dioxide into the blood from the tissues.
What are the similarities and differences between gas exchange in mammals and fish?
Mammals and insects both get their oxygen from air, while fish get oxygen from water. Water has a much lower oxygen concentration than air, and is harder to ventilate because it is more viscous. This means fish need to have a more efficient gas exchange system to get enough oxygen from the water.
What is the carbon dioxide absorbed from the blood?
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
How are oxygen and carbon dioxide exchanged in the respiratory system?
Gas Exchange Between Alveolar Spaces and Capillaries. The function of the respiratory system is to exchange two gases: oxygen and carbon dioxide.
Where does gas exchange take place in the lungs?
Where does oxygen go after passing through the blood?
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.
How is carbon dioxide transported in the body?
Carbaminohemoglobin is formed when carbon dioxide binds with hemoglobin. This process is similar to how oxygen is transported. Approximately 10% of carbon dioxide is transported by dissolving and diffusing into blood plasma. Approximately 70% of carbon dioxide is transported as bicarbonate.
How does the respiratory system exchange oxygen and carbon dioxide?
Exchanging Oxygen and Carbon Dioxide. 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.

How does the cardiovascular system pump blood through the lungs?
Perfusion is the process by which the cardiovascular system pumps blood throughout the lungs. The body’s circulation is an essential link between the atmosphere, which contains oxygen, and the cells of the body, which consume oxygen.
