Why do people need air and how the lungs? Source:

The Breath is a very important process, during which the body receives oxygen and removes carbon dioxide. Without oxygen, people can survive no more than 5-7 minutes, so the lungs – the main respiratory organ protected by the rib cage from damage. In the lungs gas exchange occurs: oxygen from air enters the blood and carbon dioxide is released from the blood directly to the lungs. As you know, the person has two lungs, but despite the same function, they have different sizes. According to , the right lung is shorter, because it frees up space for the liver which is right underneath it. Left lung already, because the heart needs space. And in 2017 , the lungs have an additional function – they are involved in the process of hematopoiesis and may play a major role in it.

How lungs work?

According to , an adult usually does 15 to 20 breaths per minute, which is about 20 000 breaths a day. Infants usually breathe faster than adults. For example, the normal respiratory rate of a newborn is around 40 times per minute, while average respiration rate at rest for adults is 12 to 16 breaths per minute. Each lung has its own pleural SAC. That's why when one is damaged, the other can continue its work. The right lung is divided into three different divisions, called lobes. In the left lung only two lobes, which consist of cancellous tissue surrounded by a membrane called the pleura. The pleura separates the lungs from the chest wall.

When the lungs expand , and when compressed, emit carbon dioxide. In the help of the diaphragm and chest, which pumped his lungs. When a person breathes, the air passes down the throat and into the trachea. The trachea splits into smaller passages – bronchial tree whose branches grow into each lung. The branches branch out into smaller units along the length of each side of the lung, and the smallest branches are called bronchioles, each of which is equipped with an air bag – alveoli. According to the Department of anatomy in the lungs, there are about 480 million alveoli.

human Lungs vary in size, but functions the same

The walls of the alveoli are covered with a large number of capillary vessels. Oxygen passes through the alveoli, capillaries and the blood transferred to the heart and then pumped throughout the body to tissues and organs. As oxygen enters the bloodstream and carbon dioxide passes from the blood into the alveoli and is then removed from the body. This process is called gas exchange. When a person breathes shallowly, the body accumulates carbon dioxide. As scientists have found that this buildup causes a yawn.
