How is carbon dioxide transported in human body?

Answer 1

O2 and Co2 are transported throughout human body by blood. 97% of O2 combines with haemoglobin of RBCs to form oxyhaemoglobin within the lungs. The oxyhaemoglobin then gives out O2 to all the cells. The remaining 3% gets dissolved in blood plasma. 70% of CO2 gets dissolved in blood plasma to reach the lungs from the tissues. The remaining contents of Co2 then combines with haemoglobin to form carboxyhaemoglobin to reach the lungs from the tissues.

Answer 2

Deoxygenated blood comes into the vena cava, through the right atrium, through the tricuspid valve, and into the right venticle of the heart. It is then pumped out through the pulmonary artery, to the lungs. This is the pulmonary circuit of the circulatory system.

In the lungs, red blood cells, or erythrocytes, pass close to the alveoli in the lungs, which are rich in oxygen, O2-. The oxygen then bonds with the iron, Fe2+, within haemoglobin, in the red blood cell. The opposite happens with CO2, which is transported into the alveoli ready to be exhaled. The blood is now oxygenated, and is transported back to the left side of the heart through the pulmonary vein. It is then pumped down into the right ventricle from the right atrium, and back up throught the bicuspid valve and out through the aorta into the body.

This is now the systemic part of the circulatory system. As oxygen travels around the body through arteries and into smaller capillaries, the oxygen moves from a high to a low concentration into tissues and cells, allowing them to respire. The C02 made during respiration joins with the haemoglobin to form deoxyhaemoglobin. This deoxygenated blood is transported back to the heart through veins, and thus the cycle begins again.

Answer 3

When you inhale oxygen, the oxygen goes to your lungs (this is were gaseous exchange takes place). Meanwhile, the blood will be getting pumped out around the body by your heart so the blood gets pumped by your heart to your lungs were the blood gets oxygenated(have oxygen). When your blood has been oxygenated, it goes back to your heart and your heart transports the oxygenated blood around the body. As for carbon dioxide, carbon dioxide doesn't get transported in the blood its actually a waste product.

Answer 4

Carbon dioxide is transported in the human body through three main methods: dissolved in plasma (around 7-10%), bound to hemoglobin (around 20-30%), and as bicarbonate ions (around 60-70%). The majority of carbon dioxide is carried as bicarbonate ions, which form from the reaction of carbon dioxide with water in the red blood cells. The bicarbonate ions are then transported back to the lungs where they are converted back into carbon dioxide and exhaled out of the body.

Answer 5

Carbon dioxide is either dissolved into the blood, or when blood flows through capilliaries, CO2 is diffused from tissues into it (:

Answer 6

Both oxygen and carbon dioxide bond with haemoglobin. Oxyhaemoglobin is carried from the lungs, carboxyhaemoglobin is carried to the lungs

Answer 7

Here it is... Your lungs bring fresh oxygen into your body. They remove the carbon dioxide and other waste gases that your body's doesn't need.

Answer 8

Carbon dioxide is transported by the blood stream back to the lungs where it is expelled.
