Vague nerve
Parasympathetic control of heart, lungs, digestive tract
Liquid protein substance that coats the alveoli in the lungs, decrease surface tension, keeps alveoli expanded
Surfactant
Blood enters lungs through right side of heart bypasses alveoli and returns to left side of heart in an unoxygenated state
Intrapulmonary shunting
The pericardial sac filling with fluid and not allowing ventricles to fill with blood
Cardiac tamponade
Blood clots that form in the pulmonary circulation and blocks the flow of blood through the pulmonary vessels. Prevents blood from going from right to left side of heart
