Unit 4 Lesson 9 (semester B) Flashcards
atmospheric pressure
the pressure of air in the atmosphere
carina
ridge formed by the hyaline cartilage where the right and left bronchi begin
dyspnea
difficulty breathing
external respiration
the exchange of gases between the lungs and the blood of the pulmonary capillaries
hemothorax
when blood enters the pleural space, decreasing intrapleural pressure and causing a collapse of the lung on the affected side
internal respiration
the exchange of gases between tissue cells and the blood in the capillaries
intrapleural pressure
the pressure between the visceral and parietal pleurae
intrapulmonary pressure
the pressure inside the lungs, specifically the alveoli
lower respiratory system
the trachea, primary, secondary and tertiary bronchi (left and right), the bronchioles, and the alveolar ducts
pneumothorax
collapse of a lung caused by air entering the pleural space.
pulmonary ventilation
“breathing” or the movement of air into and out of the lungs
respiratory membrane
a membrane that is made up of the walls of the alveoli and the capillary wall
upper respiratory system
the nose, pharynx, larynx, esophagus, trachea, and other components above the lower respiratory system
ventilation
the act of breathing
