midline that divides the nasal cavity

three-mucosa covered projections or lobes which greatly increase the surface area of the mucosa exposed to the air. Also increases air turbulence in the nasal cavity

a partition that separates the nasal cavity from the oral cavity

lightens the skull and acts as a resonance chamber for speech. They also produce mucus, which drains into the nasal cavities

a muscular passage way about 13 cm long that vaguely resembles a short length of red garden hose. Also called the throat

often called the adenoid

voice box

routes air and food into the proper channels and plays a role inspeech

an eight rigid hyaline cartilage and a spoon-shaped flap of elastic cartilage

largest of the hyaline cartilages. Commonly called the adam's apple

vocal folds and the slitlike passageway between them are called ______________

also known as the windpipe that is reinforced with C-shaped rings of hyaline cartilage

the muscle that lies next to the esophagus and completes the wall of the trachea posteriorly

a procedure in which the air in a person's own lungs is used to pop out, or expel an obstructing piece of food

medial depression of the main bronchi

most central area of the thoracic cavity which houses the heart, great blood vessels, bronchi, esophagus, and other organs

the narrow superior of each lungs which is deep to the clavicle

the broad lung area resting on the diaphragm

covers the surface of the lungs

lines the walls of the thoracic cavity

what is the purpose of your pleural fluid

the smallest of the conducting passageways after the main bronchi

the main functional and structural unit of the respiratory system

dust cells that wander in and out of the alveoli picking up bacteria, carbon particles, and other debris

these connect neighboring air sacs and provide alternative air routes for air to reach alveoli whose feeder bronchioles have been clogged by mucus or otherwise blocked

coats the gas-exposed alveolar surfaces and is very important in the lung function

the cornerstone of all energy producing chemical reactions and occur in all cells

refers to the respiratory volume

the amount of air that can be taken in forcibly above the tidal volume

the amount of air that can be forcibly exhaled beyond tidal expiration

the amount of air that cannot voluntarily be expelled after strenuous expiration

total amount of exchangeable air

air that remains in the conducting zone passageways and never reaches the alveoli

results of reflex activity, but some may be produced voluntarily like coughs and sneezes

produced by the air rushing through the large respiratory passageways (trachea and bronchi)

occur as air fills the alveoli

the actual exchange of gases between the alveoli and the blood

the gas exchange process that occurs between the blood and the tissue cells

caused by the inadequate oxygen delivery to the body tissues
