Transport Of Respiratory Gases

Once the respiratory gases have diffused in the lungs resulting in the blood becoming o 2 rich and co 2 being exhaled the next stage of transporting the o 2 rich blood to the tissues that need it takes place. Although carbon dioxide is more soluble than oxygen in blood both gases require a specialized transport system for the majority of the gas molecules to be.

At the same time the next batch of co 2 rich blood must be brought to the lungs for the process to take place again.

Transport of respiratory gases. Two gases in particular carbon dioxide co2 and oxygen o2 are used and dispensed of regularly during respiration. In order for the exchange of oxygen and carbon dioxide to occur both gases must be transported between the external and internal respiration sites. Transport of oxygen oxygen is poorly soluble in plasma so that less than 2 percent of oxygen is transported dissolved in plasma.

Carbon dioxide diffuses from body cells into the interstitial fluid before entering the capillary blood. Transport of gases the other major activity in the lungs is the process of respiration the process of gas exchange. Oxygen is transported in the blood in two ways.

The function of respiration is to provide oxygen for use by body cells during cellular respiration and to eliminate carbon dioxide a waste product of cellular respiration from the body. It will be removed from the body once they become dissociated from one another. In order for the exchange of oxygen and carbon dioxide to occur both gases must be transported between the external and internal respiration sites.

After carbon dioxide enters the blood it is transported in one of the three ways. Gas transport in blood during respiration it is extremely important for gases to be transported within the blood in order for its nutrients to be used and also for its wastes to be expelled. The vast majority of oxygen is bound to hemoglobin a protein contained within red cells.

Hemoglobin is composed of four iron containing ring structures hemes chemically bonded to a large protein globin. Most oxygen 98 5 percent carried in the blood is bound to the protein hemoglobin in red blood cells. The function of respiration is to provide oxygen for use by body cells during cellular respiration and to eliminate carbon dioxide a waste product of cellular respiration from the body.

The transportation of gases throughout the body takes place in the bloodstream through the action of the cardiovascular system heart and blood vessels as can be seen. Although carbon dioxide is more soluble than oxygen in blood both gases require a specialized transport system for the majority of the gas molecules to be moved between the lungs and other tissues. The transport of carbon dioxide is more complex.

A small amount of o 2 1 5 percent is carried in the plasma as a dissolved gas. Carbon dioxide has the ability to attach to hemoglobin molecules. About 7 is dissolved in the plasma.

In the bicarbonate buffer system the most common form of carbon dioxide transportation in the blood carbon dioxide is finally expelled from the body through the lungs during exhalation. A fully saturated oxyhemoglobin hbo 2.
