Glucose is carried through the circulation in the blood plasma.
Carbon dioxide is primarily carried in the bloodstream in the form of bicarbonate ions (HCO3-) in the plasma. However, a small amount of carbon dioxide is also carried bound to hemoglobin in red blood cells.
The haemoglobine found in the red blood corpuscles carries the carbon dioxide in the form of carboxyhaemoglobin .
The lungs are where carbon dioxide exchange takes place. Part of the respiratory system.
Carbon dioxide diffuses out of respiring cells into the blood. Part of it is carried by the same protein in red blood cells that carries oxygen-hemoglobin. The blood is carried into the heart, which pumps it into the lungs.
Red Blood Cells
Red blood cells (erythrocytes)
Most of the carbon dioxide in your body is in the form of bicarbonate. This is made by your kidneys. Bicarbonate is used to keep the acids and bases in your blood in balance. It is carried in the liquid part of the blood called the serum.CO2 can be found as bicarbonate, carbonic acid, and dissolved CO2. The blood picks up CO2 from each and every cell in your body by way of a very tiny capillary.
There is a part of the brain called the medulla oblongata which detects increased carbon dioxide levels in the blood and triggers the breathing reflex. Breathing then allows the excess carbon dioxide to escape by way of the lungs, as oxygen is acquired.
Taking in oxygen and giving out carbon dioxide is called breathing. Breathing is only a part of the process Respiration. In respiration, th lungs take in oxygen, which mixes with blood and is then circulated to each and every cell of the body. After this, in a cell, the oxygen is utilised for oxidation of food materials to generate energy for various metabolic processes. This process liberates carbon dioxide since it is a chemical reaction involving many steps. This carbon dioxide is then carried from each cell by the blood to reach the lungs where it is expelled out.
