How does the lungs work in the human body?

With the function of exchanging the gases that help the body absorb oxygen and eliminate carbon dioxide, the lungs are a very important part of the human body. In addition, the lung also plays a number of roles such as helping to metabolize some biochemical substances, filtering some toxins in the blood.

Breathing is an extremely important part of sustaining life. People can fast for more than 10 days, fasting for about a week to ten days but only hold their breath for about 30-40 seconds. Longer, we will die.

Every day, people breathe in and release about 10,000 liters of gas every day.
