The respiratory system has a single function in the body that is to supple oxygen and get ride of the carbon dioxide.
Locate Those Lungs
Your lungs are in your chest, and they are so large that they take up most of the space in there. You have two lungs, but they aren't the same size the way your eyes or nostrils are. Instead, the lung on the left side of your body is a bit smaller than the lung on the right. This extra space on the left leaves room for your heart.Your lungs are protected by your rib cage.
A Look Inside Lungs
The nose is the only part of the respiratory system which we can see. It leads to the pharynx(throat) , the larynx(voice box) and the trachea.At the bottom, the trachea divides into two main tubes which are known as bronchi which lead into the left and right lungs. Each bronchus divides into smaller and smaller tubes, the smallest being bronchiole. Each bronchiole has a sac like structure called alveolus where the exchange of oxygen and carbon dioxide takes place. The alveoli are filled with blood capillaries which are so tiny that even the tiniest blood cell can march through them!
All About Inhalation
As you inhale or breathe in oxygen, the diaphragm flatten and the intercostal muscles expand to give the lungs more space to inhale air. Also the ribs elevate and air flows into the lungs. Not only this, as you breathe air through the nose, the mucus and hair present in it, trap the dirt particles and filter the air. Even if you breathe through the mouth, the cilia present in the inner lining of the trachea filter the air and do not allow dust particles to go inside.
Thank You, Alveoli!
Our lungs have about 600 million alveoli in them. The alveoli are filled with blood capillaries and the oxygen in the air travels from the air molecules through the capillaries into the blood cells making the blood oxygenated. The oxygenated blood is then carried to the heart which distributes it to different parts of the body.
Waiting To Exhale
When you exhale the diaphragm moves upwards and the ribs depress. The intercostal muscle to create a smaller space in the lungs and air is forced out of the lungs. The deoxygenated comes to the alveoli where the alveoli get all the carbon dioxide and other wastes which are then carried to the trachea, larynx, pharynx and finally out of the nose or the mouth.
