Respiratory System

Trachea A long tube connecting the pharynx, mouth and nasal cavities to the bronchi. It's supported by rings of cartilage which support the trachea during inhalation when the pressure in the lungs is negative.
Bronchi It connects the trachea to the lungs with one going into each lung. It has a similar structure to the trachea and is supported by cartilage rings during negative pressure.
Alveoli They are millions of tiny little sacs that are located in both lungs. The walls of the alveoli are thin and moist thus allowing gaseous exchange and the transportation if gases from inside the alveoli to the blood capillaries.
Capillary Network Around The Alveoli They are fine vessels that transport high oxygen blood from the lungs to the pulmonary vein and low-oxygen blood from the pulmonary artery to the lungs for exhalation. They surround each alveolus, maximising the surface area.
