Mechanism of Transport of Gases

Mechanism of Transport of Gases

We breathe in air (with oxygen) through our nose/mouth. In the lungs, thin air sacs (alveoli) are close to blood vessels. Oxygen moves from the air sacs into the blood, while carbon dioxide exits the blood and goes into the air sacs to be exhaled. This carbon dioxide waste from our cells travels in the blood to the lungs for exhalation....

Transport of Carbon Dioxide in the Blood

When the process of cell respiration is completed, tissues produce carbon dioxide as an end product. After that, carbon dioxide from the cells disperses into blood and interchange with the oxygen present in blood under normal resting conditions. About 3.7 ml of carbon dioxide reaches 100 ml of blood. It is carried by both plasma and hemoglobin of blood....

Conclusion – Transport of Carbon Dioxide in the Blood

The transport of gases, particularly carbon dioxide, in the blood is a critical process that ensures the removal of metabolic waste from the body. Carbon dioxide is transported in three main forms: dissolved in plasma, as bicarbonate ions, and bound to hemoglobin as carbaminohemoglobin. These mechanisms facilitate efficient gas exchange, allowing carbon dioxide produced by cellular respiration to be carried to the lungs for exhalation....
