Question

explain the schematic respiration of gaseous exchange in tissues

Answer 1

The mechanism of gaseous exchange between tissues and blood is as follows:

The blood reaching the tissues has higher concentration of oxygen than in the cells so it gets diffused into the cells.

The carbon dioxide, which is formed in the cells, gets accumulated in higher concentration as compared in the blood, so it easily diffuses into the blood.

The blood with CO2 takes this gas to the lungs, from where it is expelled out during exhalation.

Answer 2

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 CO2 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.
