Carbon dioxide is removed from blood by respiratory system.
That is carbon dioxide. It is a raw material
The respiratory system supplies oxygen to the blood cells and removes waste gases from the blood cells. Carbon dioxide is the primary waste gas that is removed.
Removal of iron from aluminous material such as bauxite is effected by treatment with a gas mixture comprising sulphur dioxide and carbon monoxide in a first step, followed by chlorination in a second step whereby ferric chloride is produced and removed by volatilization.
The function of the respiratory system is to allow gas exchange it, taking oxygen into the blood and removing carbon dioxide from the blood. The oxygen absorbed is used by the body cells to carry out respiration, the release of energy from food: sugar + oxygen ----> water + carbon dioxide + ENERGY The carbon dioxide made by respiration is removed when we breathe out.
The respiratory system functions almost elusively to add oxygen to the blood and remove carbon dioxide. Incidental to this it also can be a way to remove some volatile chemicals from the blood.
