What are the main functions of the lungs?

The lungs are located in the chest and cover the heart. Two lobes on the left, three lobes on the right, and five lobes on the right. The lung is connected with the larynx and nasal cavity, so the larynx is the portal of the lung.

Chinese medicine believes that the lung governs qi and breath, that is to say, the lung has the functions of governing breath and qi. The lung is the place where gas exchange takes place inside and outside the body. The human body inhales the fresh air in nature through the lungs and exhales the turbid air in the body, so that the gas inside and outside the body can be continuously exchanged, thus ensuring the normal metabolism of the human body.

The fresh air inhaled by the lungs combines in the lungs and flows through the veins of the heart to make the blood run. The lung governing qi can not only assist the heart to run blood, but also preside over and regulate the viscera and organs of the whole body, which has a regulating effect on the qi of the whole body.

These functions of the lung can dredge and regulate the metabolism of body fluids, mainly in two aspects: first, the hair growth function of the lung, which mainly regulates the excretion of sweat and makes it normal.

Secondly, lung qi can continuously transport water and liquid in the body downwards, and generate urine through the gasification of the kidney and bladder, and then excrete it. This is the role of the lung in regulating body fluid metabolism.

In addition, the lungs can also regulate the whole body blood. Air gathers in the lungs through the meridians, exchanges gas through the breathing of the lungs, and then dredges and distributes to the whole body. Therefore, the normal circulation of blood depends on the normal distribution and regulation of lung qi.
