When we take in we take in Oxygen, which achieves the lung alveoli. Oxygen at that point diffuses into the blood of the encompassing vessels from the alveoli which have a high grouping of Oxygen by dispersion. This oxygenated blood is then dispersed to all the body cells by heart. In the wake of providing oxygen to the body cells, the blood gathers carbon dioxide which is created by cell respiration in the cells. The tissues or cells have a high grouping of $CO _2$ than the blood so carbon dioxide diffuses from high focus to low fixation. The blood conveys carbon dioxide to lung alveoli. The trading of gasses happens in the alveoli and tissues. The oxygen breathed in is transported to every one of the parts of the body while carbon dioxide delivered to the cells is gathered from the cells and breathed out.
