Chp 12- Respiratory System Flashcards
External respiration
Exchange of air in lung capillaries
Internal respiration
exchange of gases in the cells
Mediastinum
middle of chest where trachea divides into two branches
bronchi
each leads to seperate lung
lungs
lobes are not mirror images
hilum
blood vessels, nerves, lymphatic tissue, and bronchial tubes enter and exit
adenoids
lymohatic tissue in the nasopharynx; pharyngeal tonsils
alveolus
air sac in lung
apex of lung

nares
opening through the nose carrying air into the nasal cavity
palatine tonsil
one pair of almond shaped masses of lymphatic tissue in the oropharynx

one of the air cavities on the bones near the nose
parietal pleura
outer fold of pleura lying closer to the ribs and chest wall
pharynx
throat
pleura
double folded membrane surrounding each lung
pulmonary parenchyma
essential parts of the lungs, responsible for respiration; bronchioles and alveoli
visceral pleura
inner fold of pleura lying closer to the lung tissue
