oxygen
Oxygen is a specific molecule that diffuses into the blood in the lungs during the process of respiration. This exchange occurs in the alveoli, where oxygen moves from the air sacs into the bloodstream to be transported to tissues in the body.
your lungs
In the human body, air is brought into contact with blood in the lungs. This happens through the process of respiration, where oxygen from the air diffuses into the blood in the capillaries surrounding the alveoli in the lungs, and carbon dioxide from the blood diffuses into the air to be exhaled.
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
As blood moves through the lungs, oxygen is exchanged for carbon dioxide. Oxygen diffuses from the air in the lungs into the blood, increasing the oxygen level in the blood. Conversely, carbon dioxide diffuses from the blood into the air in the lungs, decreasing the carbon dioxide level in the blood.
This process occurs in the capillaries of the lungs. Here, oxygen from inhaled air diffuses into red blood cells in exchange for carbon dioxide, which then diffuses out of the red blood cells and is exhaled from the body.
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.
The lungs remove carbon dioxide from the bloodstream. As blood circulates through the lungs, carbon dioxide diffuses from the blood into the lungs to be exhaled out of the body.
Gas exchange between the air and the blood occurs in the alveoli of the lungs. The alveoli are tiny air sacs where oxygen from the air diffuses into the blood and carbon dioxide from the blood diffuses into the air to be exhaled.
In the lungs. The blood is pumped from the right side of the heart to the lungs. Air moves into the trachea, the bronchi and finally to the alveoli. From the alveoli oxygen diffuses into the microcapilaries (small blood vessels) of the lungs.
Carbon dioxide and oxygen are exchanged in the lungs during the process of respiration. Oxygen from the air we breathe diffuses into the blood in the lungs, while carbon dioxide from the blood diffuses into the air we exhale. This exchange occurs in the alveoli, which are small air sacs in the lungs.
