The lubricant that reduces friction when layers of the pleura rub against each other during breathing.
serous fluid
The term for the mechanical process of moving air in and out of the lungs
Pulmonary ventilation or ventilation
The point at which the trachea splits into the right and left mainstem bronchi is called the?
Carina
A method for delivering a high concentration of oxygen that has a reservoir bag attached to a mask, with a one-way valve between them that prevents the patient's exhaled air from mixing with the oxygen in the reservoir bag
