Breating air is necessary for kepping humans alive. Through respiration we take in the in the oxygen our cells need to transform into energy and our body releases the carbon dioxide it doesn´t need. Your lungs make up one of the largest organs in your body. They work to allow to take fresh air and get rid of stale air.
WHERE ARE THE LUNGS?
The lungs are in our chest and they are so large that they take up most of the space in there. We have two lungs, but they aren´t the same size. The lung on the left side of our body is a bit smaller than the lung on the right. This extra space on the left leaves room for our heart. The lungs are protected by our rib cage.
WHAT ARE THE PARTS OF THE LUNGS?
WHAT IS THE PROCESS OF THE RESPIRATORY SYSTEM?
The air enters the body through our nose, then it goes down through the pharynx, larynx, trachea, bronchi, bronchioles and finaly the alveoli.
