The lungs play a vital part in the life of a human being. They are responsible for the intake of oxygen into the body through their large surface. This oxygen is then absorbed into the blood, and it is from here that it is transported to every other art of the body. Apart from oxygen, the lungs expel carbon dioxide as well as other unwanted gases.
Therefore, they help to make the body cleaner, and to make it more refreshed. Lungs are connected to the large breathing system that starts with the nose on the outside to the diaphragm. The system also consists of the bronchus, trachea, and other parts. It however is balling that some people hardly know anything about how this system works. Here are some facts you need to know about lungs and breathing.
The average surface area of human lungs can equal a tennis court
Although the lungs may seem like two averagely sized organs on the left side of the chest, they actually have a larger surface area than you can imagine. This is the surface on which the oxygen found in the air that we breathe is absorbed to the red blood cells. This surface is made large because of the way there are many channels through which air flows through it.
The air is taken in circles throughout the entire lung. This is the reason it feels spongy because inside it, there is nothing other than lots of tracts that are meant to facilitate the flow of air as it is exchanged.
The two lungs are not the same size
If you look at the pictures of human lungs, you will notice that they are not the same size. The right lung is wider than the left, but the left is longer than the right. researchers have established that the reason behind this is to create room for other organs in the chest. For instance, the right lung is shorted to create room for the liver, which is positioned just below it.
On the other side, the left lung is narrowed because it shares the same space on that side with the heart. However, the difference in size and shape does not mean that their functions are different.
The lungs can get sick
There are a variety of diseases that affect the lungs and the entire respiratory system. These diseases can be mild or chronic based on the nature of infection. For instance, there are people who have lived for many years with asthma, despite the fact that it is a disease that causes difficulty in breathing. Other diseases include pulmonary tuberculosis, lung cancer, and obstructive pulmonary disease. The best way to avoid or manage these diseases is to watch your lung health.
Once you know these facts about lungs and breathing, you need to also know how to find the right doctor just in case your lungs get infected. It is important to have the checked early so that the infections can be treated on time especially now that you know that most of them are treatable.
