THE RESPIRATORY SYSTEM

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide.

The primary organs of the respiratory system are lungs, which carry out these exchange of gases as we breathe 

Red blood cells collect the oxygen from the lungs and carry it to the parts of the body with is needed, during the process, the red blood cells collect the carbon dioxide and transport it back to the lungs, wheres it leaves the body when we exhale.

PARTS OF THE RESPIRATORY SYSTEM:

The nostrils: Are involved air intaked, they bring air into the nose, where air is warmed and humidified.

Trachea: Is also known as windpipe. The trachea filters the air we inhael and brunches into the bronchi.

Lungs: The main organ of the respiratory system is lungs. Lungs are the site in body where 

oxygen is taken into a carbon dioxide is expelled out. The  reed blood cells, present in the blood picks up the oxigen in the lungs and carry and distribute the oxigen to all body, cells that need it. 

Alvelous: Alvelous is the sac like structure present in the lungs which the gaseous exchange  takes place.

Diaphragm: Breating begins at the bottom of the lungs  which is know as diaphagram,  when we breathe in the diaphagram contracts and flatten out and pull downward .Due to this movement the space in the lungs increase and pulls air into the lungs.
