The process of respiration

Hello friends,

You're all fine, aren't you? Today I am going to tell you about what I learned about the process of breathing in school. The process of inhalation and exhaling is something that happens spontaneously in all of us. It happens as if we do not know. But even though we do not know how it happens, there is a complex process going for it on inside the body. This is done by the respiratory system and the circulatory system. Inhalation and exhalation involve the get of oxygen from the outside air into the body and the release of unwanted carbon dioxide into the atmosphere. This basic function is caused by two of the basic functions of lung ventilation and the exchange of oxygen and carbon dioxide between the air and blood in the lungs.

A few things must be completed for the inhalation to take place. The first is that the pressure in the lungs is lower than the pressure in the outside atmosphere. Only then can the oxygen in the atmosphere be absorbed into the lungs. In order to reduce the pressure, the lungs expand and increase in volume. This is due to the contraction of the external rib muscles and the contraction of the great diaphragm. When the external rib muscles contract, the that muscles lifts up and pushes the chest forward.
The volume of the thoracic cavity increases anteriorly and vertically due to the contraction of the rib muscles and the great diaphragm. What happens next is that the pressure in the pleura cavity decreases. As the pressure in the pleura cavity decreases, the lungs are drawn toward the pleura, causing the inhalation process to begin in a pressure sequence.

Exhalation.

The exhalation process is completely opposite to the inhalation process. What happens here is that the pressure in the lungs exceeds the pressure in the outside atmosphere, releasing carbon dioxide into the atmosphere. The lungs contract and decrease in volume to increase the pressure in the lungs. The outer rib muscles relax and the great diaphragm relax causes this decrease in volume. And the external rib muscles relax and return to their original position. Relaxation of the rib muscles and relaxation of the great diaphragm reduces the volume of the thoracic cavity. As the pressure in the pleura cavity increases, the lungs, which were drawn towards the pleura, regenerate and the air inside the lungs exits the atmosphere through a pressure sequence.
