Partial pressure is the pressure that comes from an individual gas in a mixture of gases. It is represented as pO2 for oxygen and pCO2 for carbon dioxide. The table below shows the partial pressures of these gases in the atmospheric air and different sites of gas exchange. Respiratory Gas ...

If we assume that the conditions of temperature and pressure for all gases remain fixed (as they roughly do in the alveoli) then it is the inherent differences between different gases that determine their solubility. Carbon dioxide is inherently more soluble than oxygen, and thus diffuses much ...
Tools Share Cite Recommend Abstract: Gas exchange involves the exchange of gases between the lung and the blood. The gases of interest are oxygen and carbon dioxide. The general objectives behind this chapter are to leave you with enough basic physiological knowledge that would enable you to ident...
Additionally, a certain amount of gas per liter of blood has to be exchanged; therefore, the blood needs to remain in the oxygenator long enough to exchange a sufficient amount of oxygen and carbon dioxide. This also limits the blood flow velocity. In order to use the oxygenator to its ...
equilibrium is reached. This is what happens when oxygen moves from the alveoli into the blood. • Now let's look at the diffusion of carbon dioxide. Although both gases are at the same pressure, far more carbon dioxide dissolves in the liquid than oxygen. This occurs because carbon dioxid...
This culminated in the work of Lavoisier who first clearly elucidated the nature of the respiratory gases, oxygen, carbon dioxide and nitrogen. At that time it was thought that oxygen was consumed in the lung itself, and the fact that the actual metabolism took place in peripheral tissues ...

The mechanism of exchanging gas (oxygen and carbon dioxide) between inside and outside of the human body is known as gas exchange. The five phases of gas exchange include inhaling, exhaling, pulmonary ventilation, internal respiration, and cellular respiration....
What is the physical mechanism of the transport of oxygen and carbondioxide? Explain how the structure of the gastrointestinal tract is related to it's functions. Explain how you describe the journey of blood through the heart and lungs, starting with the vena cava and finishing with the aorta...
