In the lungs, oxygen diffuses from the alveoli into the bloodstream through the process of gas exchange facilitated by differences in partial pressure.
Blood gives up carbon dioxide and obtains oxygen in the capillaries within the lungs during the process of gas exchange. In the lungs, carbon dioxide diffuses from the blood into the alveoli to be exhaled, while oxygen diffuses from the alveoli into the blood to be carried to the body's tissues.
The aorta is a large artery that carries oxygenated blood from the heart to the body. The alveoli are small air sacs in the lungs where gas exchange occurs. The connection between the aorta and alveoli is through the process of oxygen exchange, where oxygen from the inhaled air diffuses into the blood in the alveoli and is then carried by the aorta to the body tissues.
Gas exchange takes place in the alveoli of the lungs and in the capillaries. The direct process of gas exchange occurs in alveoli located within the lungs. Blood is sent from the heart through pulmonary arteries, exchanging the carbon dioxide within erythrocytes (red blood cells) for oxygen provided by the air lungs store when inhaling. In the capillaries, oxygen diffuses through the capillary walls into the tissues, and carbon dioxide diffuses from the tissues into the capillaries.
because the molecules in a gas have no fixed position relative to one another and can move freely.
Oxygen typically diffuses the fastest through tissues due to its small molecular size, allowing it to pass through cell membranes easily. This property is essential for efficient delivery of oxygen to cells for physiological processes.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Oxygen diffuses into cells. Carbon dioxide diffuses out.
Most gas exchange between blood and tissues takes place in the capillaries. This is where oxygen diffuses from the blood into the tissues, and where carbon dioxide diffuses from the tissues into the blood. The thin walls of the capillaries allow for efficient exchange of gases.
Chlorine gas diffuses the fastest among the gases listed. This is because gases with lower molar masses diffuse faster, and chlorine gas has the lowest molar mass among the options provided.
Oxygen diffuses into the blood from the air in the lungs. This occurs in the alveoli, which are small air sacs in the lungs where gas exchange takes place. Oxygen crosses the thin alveolar membrane and enters the bloodstream to be carried to the body's tissues.
Gas diffuses in space.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
During gas exchange in the lungs, oxygen from inhaled air diffuses into the blood within the capillaries surrounding the alveoli, while carbon dioxide, a waste product of metabolism, diffuses from the blood into the alveoli to be exhaled. This process enriches the blood with oxygen, which is then transported to tissues throughout the body for cellular respiration. The removal of carbon dioxide helps maintain the body's pH balance and prevents respiratory acidosis. Thus, gas exchange is crucial for sustaining life by ensuring a continuous supply of oxygen and the removal of carbon dioxide.

In the lungs, oxygen diffuses from the alveoli into the bloodstream through the process of gas exchange facilitated by differences in partial pressure.
Gas exchange occurs in the alveoli of the lungs, where oxygen from inhaled air diffuses into the bloodstream and carbon dioxide diffuses out. Nutrient exchange occurs in the small intestine, where nutrients from digested food are absorbed into the bloodstream to be transported to cells throughout the body.
