Breathing is the function of our body to let air flow to the lungs. It is important because it serves the purpose of bringing the amount of oxygen the body needs to work properly, and flushing out the toxic substances our body produces.
The diaphragm also plays its important role in respiratory system because it creates more space in our chest cavity, allowing the lungs to expand when we inhale.
The larynx connects the naso- and oro- pharynx with the trachea, functioning in air conduction, vocalisation and in obstructing passage of ingesta into the trachea during deglutition. The trachea divides into left and right mainstream bronchi. Bronchi give away to smaller conducting airways, bronchioles.
The walls of the alveoli share a membrane with the capillaries, this relatively lets the oxygen and carbon dioxide diffuse between the respiratory system and bloodstream. They bring oxygen into our body through inhalation and send carbon dioxide out called exhalation and overall process is respiration
Pneumonia is a life threatening illness because if our lungs is filled with fluid then they won’t be able to function normally and won’t be able to transfer enough oxygen to your blood or get rid of the carbon dioxide in our bloodstream
It was believed that a asteroid hit the Earth (specifically Mexico) when the asteroid hit it caused a freezing darkness due to dust and debris being kicked up by the asteroid . The dust and debris blocked the sunlight causing a temperature drop.
