What is the Respiratory System?
Respiration is also refered to cellular respiration because of chemical reactions in the cell.
Nose: Air enters the body through the nostrils. The lining of the nose is coated with cilia and mucus, which trap particles and warm and moisten the air.
Pharynx: Air moves from the nose downward into the throat, or pharynx. Part of the pharynx is also a passageway for food.
Trachea: Leads from the pharynx toward the lungs. The walls of the trachea are made up of rings of cartilage which protect the trachea and keep it from collapsing.
Bronchus: Air moves from the trachea into the right and left bronchi. One bronchus leads to each lung. Part of each bronchus is outside the lung and part is inside.
