Carbon dioxide (CO2) is transported from the body's tissues to the alveoli primarily through three mechanisms: dissolved in plasma, bound to hemoglobin as carbamino compounds, and as bicarbonate ions (HCO3-) in the blood. In the tissues, CO2 diffuses into red blood cells, where it is converted to bicarbonate and transported in the plasma. Once the blood reaches the lungs, bicarbonate is converted back to CO2, which then diffuses into the alveoli. Finally, CO2 is expelled from the body during exhalation.

What are two gases that enter and exit from the alveolus?

It is carbon dioxide which is collected from different organs of the body by blood


Two substances that are transported in blood?

Oxygen and carbon dioxide are two substances transported in the blood. Oxygen is carried from the lungs to body tissues by red blood cells, while carbon dioxide is transported from body tissues back to the lungs for elimination.


What happens to oxygen and carbon dioxide in the alveolus?

In the alveolus, oxygen diffuses from the alveolar air sacs into the bloodstream through capillaries, where it binds to hemoglobin in red blood cells for transport to tissues. At the same time, carbon dioxide diffuses from the bloodstream into the alveoli to be exhaled out of the body during respiration.


A whaste gas that is transported in veins from the body to the lungs via the heart?

Carbon Dioxide


Air that leaves the air sacs is rich in the gas?

Oxygen is 'transported' from the lung capillaries to the body capillaries - in an inverse fashion carbon dioxide is transported from the body capillaries to the Lung Alveoli - the Answer is 'It is rich in CO2."


The highest carbon dioxide concentration will be found where in the body?

The highest carbon dioxide concentration in the body will be found in the tissues and cells, where it is produced as a byproduct of cellular metabolism. This carbon dioxide is then transported via the bloodstream to the lungs for exhalation.


How is carbon dioxide carried around human body?

Carbon Dioxide is transported throughout the body using the red blood cells' hemoglobin, which first carries Oxygen to the lungs, and then to the heart. The blood then carries deoxygenated blood back to the lungs to exhale the Carbon Dioxide.


How is carbon dioxide transported from the production to the excretion of the substance from the body?

IT is transported in the blood attached to the haemoglobin molecules in red blood cells.


What part of your body carries oxygen and carbon dioxide?

The lungs are the organs responsible for carrying oxygen into the bloodstream and removing carbon dioxide from the body. Oxygen is absorbed into the blood in the lungs and then transported to the rest of the body, while carbon dioxide is released from the blood into the lungs to be exhaled.


What happends in the lungs when oxygen and carbon dioxide are transported?

The oxygen is made of compoundants and such that when it goes through the body it's so sensitive it changes to carbon dioxide.
