bronchus (airway)

bronchiole (little airway)

carbon dioxide

larynx (voice box0

lobe (a portion)

nose

mouth

oxygen

palate

pharynx (throat)

diaphragm (also mind)

pleura (lining of lungs)

air or lung

lung

sinus (cavity)

breathing

chest

tonsil

trachea (windpipe)

uvula

structure that warms, moistens, and filters air as it enters the respiratory tract; also houses the olfactory receptors for the sense of smell

air-filled spaces in the skull that open into the nasal cavity

roof of the mouth; partition between the oral and nasal cavities; divided into the hard and soft palate

bony anterior (front) portion of the palate

muscular posterior (back) portion of the palate

throat; passageway for food to the esophagus and for air to the larynx

part of the pharynx directly behind the nasal passages

central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis

lower part of the pharynx, just below the oropharyngeal opening into the larynx and esophagus

oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion; also called palatine tonsils

lymphatic tissue on the back of the pharynx behind the nose; also called pharyngeal tonsil

small projection hanging from the back middle edge of the soft palate; named for its grape-like shape

voice box; passageway for air moving from the pharynx to the trachea; contains the vocal cords

opening between the vocal cords in the larynx

a lid-like structure that covers the larynx during swallowing to prevent food from entering the airway

windpipe; passageway for air from the larynx to the area of the carina, where it splits into the right and left bronchi

branched airways that lead from the trachea to the microscopic air sacs called alveoli

two primary airways branching from the area of the carina into the lungs

progressively smaller tubular branches of the airways

thin-walled, microscopic air sacs that exchange gases

two spongy organs in the thoracic cavity enclosed by the diaphragm and rib cage; responsible for respiration

subdivisions of the lung, with two on the left and three on the right

membranes enclosing the lung (visceral pleura) and lining the thoracic cavity (parietal pleura)

potential space between the visceral and parietal layers of the pleura

muscular partition that seperates the thoracic cavity from the abdominal cavity and that moves upward and downward to aid in respiration

partition that seperates the thorax into two compartments (containing the right and left lungs) and that encloses the heart, esophagus, trachea, and thymus gland

thin sheets of tissue that line respiratory passages and secrete mucus, a viscid (sticky) fluid

hair-like processes from the surface of epithelial cells, such as those of the bronchi, to move mucous cell secretions upward

functional tissues of any organ, such as the tissues of the bronchioles, alveoli, ducts, and sacs, that perform respiration
