        The human body comes with many complex systems, and each system has so many aspects to analyze and understand. One of these complex systems is the ventilation system of human body. In order to live, the human beings have to breathe and they live until their breathing system is working. One of the important organs in the ventilation system is lungs. Lungs are major organs in terms of respiratory system, and they have a very important job to perform for the ventilation process. When a human being breathes, the oxygen is taken in by lungs, and carbon dioxide is expelled from the lungs through mouth or nose.

        A normal ventilation process allows a human being to breathe normally, but there are many medical conditions, which make this process difficult for human beings and they face problems in breathing. One of such problems is called hyperventilation. In this condition what happens to humans is that they start breathing faster than a normal breathing range. In this condition, the human body inhales less oxygen, whereas more carbon dioxide is exhaled from the body, which disturbs the overall balance as carbon dioxide in the body is reduced rapidly. The hyperventilation can be occasional for some people, but when it occurs on frequent basis, it is a medical issue, which needs to be looked at.

        The other major issue related to ventilation system is called Hypoxia. It is a condition, where human body does not receive adequate and required level of oxygen supply, which is needed at the tissue level. This issue can generally affect a particular region of the human body, or whole body can also face its effects. There is one more related term called Normoxia, which is different from hypoxia. It is a condition, when oxygen level of supply to the human body is at a normal level. For instance, in condition of hypoxia, the range for oxygen is from 1 to 5% O2, whereas the supply range of oxygen is between 10 to 21% O2 during the Normoxia. One other issue that lungs may have is called Hemoptysis. If a person has lung cancer, he/she can have this condition where from bronchi or lungs, the blood-stained mucus happens or blood’s coughing up occurs. It is one of the critical medical conditions, where patient has to face critical consequences.
