Respiratory System - AJ

• The respiratory system is the system in your body that is responsible for the motion of breathing in oxygen and exhaling carbon Dioxide. The very prime organs of our Respiratory system is our lungs because they are the organs that exchanges between carbon dioxide and oxygen.
•  Also in the respiratory system the red blond cells take the oxygen from the lungs all the through to the rest of the body, during this process the Red blood cells take the carbon dioxide to the Lungs so it could be emptied when we exhale.
• The human body needs enough oxygen to sustain it's self. When there is a decrease of oxygen in a human body it is known as  hypoxia, but when there is a complete lack of oxygen the human body then it is called anoxia and these conditions can be fatal. When your body is without oxygen for 4 minutes then, your brain cells start dying and when most of them have died then the body will stop functioning and die.
• In humans, the average rate upon breathing is based on age. A newborn's normal breathing rate is 40 times a minute and about 20 to 40 times when they are sleeping. For adults, the average breathing rate when they are resting is at about 12 to 16 times a minute, and the healthy adults breathe 40 to 45 times a minute when they are exercising. 
• As we breathe, oxygen enters through the the nose or mouth and passes the  sinuses, which are hollow spaces in the human skull. The trachea, also called as the wind pipe filters all the the air that enters the body.
