Pulmonary - ENT Flashcards
(235 cards)
Term
Definition
fluid
partition seperating the right and left nasal cavities
paranasal sinuses
air cavities within the cranial bones that open into the nasal cavities
pharynx
serves as a food and air passageway. Air enters through the nasal cavities and passes through the pharynx to the larynx. Food enters the pharynx from the mouth and passes into the esophagus.
Adenoids
lymphoid tissue located behind the nasal cavity
Tonsils
Lymphoid tissue located behind the mouth
larynx
location of the vocal cords. Air enters from the pharynx (also called the voice box)
epiglottis
flap of cartilage that automatically covers the opening and keeps food from entering the larynx during swallowing
Trachea
passageway for air to bronchi (wind pipe)
Bronchus (pl. bronchi)
one of two branches from the trachea that conducts air into the lungs, where it divides and subdivides. The branching resembles a tree; therefore they are referred to as a bronchail tree.
bronchioles
smallest subdivision of the broncial tree
alveolus (pl. alveoli)
Air sacs at the end of the brochioles. Oxygen and CO2 are exchanged through the alveolar walls and the capillaries
Lungs
two spongelike organs in the thoracic cavity. The right lung consists of three lobes and the left lung has two.
Pleura
Double folded serous membrane covering each lung and lining the thoracic cavity with a small spave between, called the pleural cavity, which contains serous fluid.
Diaphragm
muscular partition that seperates the thoracic cavity from the abdominal cavity. It aids in the breathing process by contracting and pulling air in, then relaxing and pushing air out.
Mediastinum
space between te lungs. It contains the heart, esophagus, trachea, great blood vessels, and other structures.
