Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.
The exchange of gases between the alveolar air and pulmonary capillary blood is called pulmonary gas exchange. Oxygen diffuses from the alveoli into the capillaries, while carbon dioxide diffuses from the capillaries into the alveoli. This process is essential for the body to obtain oxygen and release carbon dioxide.
That sounds like a general description of the LUNGS.The lungs are loaded with pulmonary alveoli: small outpouchings along the walls of the alveolar sacs and alveolar ducts; through them, gas exchange takes place between alveolar gas and pulmonary capillary blood.
The respiratory membrane consists of three main structures: the alveolar epithelium, the capillary endothelium, and the fused basement membranes of both. The alveolar epithelium is a thin layer of cells lining the alveoli, while the capillary endothelium forms the inner lining of the pulmonary capillaries. Together, these structures facilitate efficient gas exchange between the air in the alveoli and the blood in the capillaries.

Diffusion due to differences in air pressures.
The process by which gaseous exchange occurs at the alveolar-capillary membrane is called external respiration. This involves the exchange of oxygen and carbon dioxide between the alveoli in the lungs and the blood capillaries surrounding them.
An alveolar plateau refers to the phase during a pulmonary function test when stable alveolar gas exchange occurs, resulting in a horizontal line on the volume-time curve. This plateau indicates that sufficient time has elapsed for oxygen and carbon dioxide to equilibrate between the alveoli and the capillaries. It is used to assess the efficiency of gas exchange in the lungs.
The layers of the respiratory membrane include the alveolar epithelium, the basement membrane, and the capillary endothelium. These layers are involved in facilitating the exchange of gases, such as oxygen and carbon dioxide, between the air in the lungs and the blood in the capillaries.
The three components of the respiratory membrane are the alveolar epithelium, the capillary endothelium, and the basement membrane between them. These components facilitate the exchange of gases (oxygen and carbon dioxide) between the alveoli and the blood in the capillaries during respiration.
Capillary Exchange is a biological term. This is where fluids, gasses, nutrients, and wastes are exchanged between the blood and body tissues by diffusion.
Blood releases carbon dioxide and acquires oxygen, in the lungs. The opposite exchange takes place throughout the body on a cellular level, as each cell consumes oxygen from the blood and releases carbon dioxide into the blood.
