Document Summary

Allows air to enter the trachea and keep food out. Divides into right/left bronchi at the transverse thoracic plane. Esophagus, trachea, subclavian artery/vein, common carotid artery, internal jugular vein: how does deoxygenated blood travel throughout the body, exits the right ventricle through the pulmonary arteries. Route one: leaves the left atrium through the aorta, goes through the body and becomes deoxygenated, goes through the superior vena cava and enters the right atrium. Branching follows bronchi and forms a capillary network around the alveoli. Supplies oxygen to lung tissues and drains via pulmonary veins: explain the flow of air from the trachea to alveolar sacs. Trachea main bronchi lobar and segmental bronchi bronchioles and terminal bronchioles. Surfactant in alveoli: what 3 things are needed in order for air to move in our or out of the lungs, a pressure gradient. Air must move from high pressure areas to low pressure areas.
