Respiratory System
Fulfilling Your Knowledge About the Respratory
What Is Respiration?
Respiration is the process in which oxygen and glucose undergo a complex series of chemical reactions inside cells, in other words..Breathing!
How Does It Work?
First, the air enters into the body through the nose and mouth. Then, the air moves from the nose down into the throat. The air goes down the trachea into the bronchus. From the bronchus the air moves to the lungs, then to the small bronchi. Where the oxygen is absorbed by the alveoli. The alveoli soon passes the oxygen into the blood which eventually leaves into the circulatory system.
Parts of the Respiratory System
Nose
Air enters the body through two nostrils. The lining of the nose is coated with cilia and mucus, which traps particles and warm and moisten the air.
Pharynx
Air moves from the nose downwar into the throat, or pharynx. Part of the pharynx is also a passageway for food.
Lung
After it reahes the lungs, air moves through smaller and samller bronchi until it reaches the alveoli. In the alveoli, oxygen passes into the blood and carbon dioxide passes out of the blood.
Gas Exchange
How this Occurs
At first their is just carbon dioxide and a little oxygen being carried. As you move through the capillary, oxygen gradually
Why Does the Body Need Oxygen
Our body needs oxygen because, so our lungs can get oxygen. Then, the circulatory system carries oxygen from our lungs and glucose form our food to our cells.
