-
-
-
nose
warms, moistens and filters air
-
sinuses
- air-filled spaces in the skull
- open into the nasal cavity
-
palate
- partition between the oral and nasal cavities
- hard and soft palate
-
pharynx
throat; food to esophagus and air to the larynx
-
nasopharynx
- part of pharynx
- behind nasal passages
-
oropharynx
- central part of pharynx
- between roof of the mouth and upper edge of the epiglottis
-
laryngopharynx
- lower part of pharynx
- below oropharynx, opens into larynx and esophagus
-
tonsils
- oval lymphatic tissue on each side of the pharynx
- filter air to protect body from bacterial invasion
-
adenoid
lymphatic tissue on the back of the pharynx (behind nose)
-
uvula
small projection hanging from the back of the throat
-
larynx
- voice box (contains vocal cords)
- passageway for air moving from the pharynx to trachea
-
glottis
opening between the vocal cords in the larynx
-
epiglottis
lid-like structure that covers the larynx when you swallow to prevent food drom entering the airway
-
trachea
- windpipe
- passageway for air from larynx to carnia, where it splits into right and left bronchus
-
bronchial tree
branched airways from trachea to alveoli
-
right and left bronchus
two primary airways branching from the carnia to the lungs
-
bronchioles
progressively smaller branches of the airway
-
alveoli
thin walled, microscopic air sacs that are for gas exchange
-
lungs
spongy organs-in throacic cavity, enclosed by diaphragm and rib cage
-
lobes
- divisions of the lungs.
- R=3, L=2
-
pleura
- membrane enclosing the lung.
- Visceral-on lung
- Parietal-lining thoracic cavity
-
pleural cavity
potential space between viscera and parietal pleura
-
diaphragm
- muscle that separates thoracic and abndominal cavities
- airds in respiration
-
mediastinum
area: lungs, heart, esophagus, trachea, thymus gland
-
mucous membrane
thin sheets of tissue that line the respiratory passages and secrete mucus
-
cilia
- hair-like projections on the surface of epithelial cells
- move mucus
-
parenchyma
- functional tissue on any organ that performs respiration
- ex: bronchioles, alveoli, ducts, sacs
