What Is Suction Pressure?
The bronchi are dilated, and the stretch receptors in the smooth muscle layer of the wall are excited by the stretch stimulus. The excitement of the stretch receptors results in the inhibition of inspiration and promotes the conversion of inspiration to exhalation. This reaction is called pulmonary stretch reflex. Muscle contraction, diaphragmatic muscle decline leads to enlargement of the thoracic cavity, negative pressure in the pleural cavity, decreased intrapulmonary pressure, and a difference in pressure between the intrapulmonary pressure and the atmospheric pressure. The internal pressure of the lungs is lower than atmospheric pressure, and the pressure difference between the air and the lungs is called inhalation. [1]

- The bronchi are dilated, and the stretch receptors in the smooth muscle layer of the wall are excited by the stretch stimulus.

The internal pressure of the lung is lower than the atmospheric pressure. [1]
- Due to the contraction of the respiratory muscles and the decline of the diaphragm muscles, the thoracic cavity is enlarged, the pleural cavity is negatively pressured, the intrapulmonary pressure is reduced, and the intrapulmonary pressure and atmospheric pressure create a pressure difference. The internal pressure of the lung is lower than the atmospheric pressure.
- When inhaling, a large amount of gas can be inhaled, and oxygen contained in the air can participate in the material circulation after inhalation.
- When inhaling a large amount of CO that cannot participate in the material cycle when inhaling, gas poisoning (that is, carbon monoxide poisoning) will occur.
