Exam 2 - Chapter 7: Respiratory System (by definition) Flashcards
microscopic hairlike structures in the respiratory system
cilia
to move or spread out at random, rather than by chemical reaction or application of external force
diffuse
moist tissue layer lining hollow organs and cavities of the body that open to the environment, sometimes called mucosa
mucous membrane
a wall dividing two cavities
septum
thin layer of tissue that covers internal body cavities and secretes a fluid that keeps the membrane moist; sometimes called serosa
serous membrane
receptors for the sense of smell
olfactory neurons
the throat
pharynx
one of the three divisions of the pharynx; sits in the posterior of the nose
nasopharynx
one of the three divisions of the pharynx, sits in the posterior of the mouth
oropharynx
one of the three divisions of the pharynx, sits just above the larynx
laryngopharynx
the pharyngeal tonsils
adenoids
what we commonly know as tonsils; sits in the oropharynx
palantine tonsils
sometimes called the voice box, contains the structures that make vocal sound possible.
larynx
leaf-shaped cartilage and flesh portion of the throat that covers the passage to the lungs while swallowing
epiglottis
the two immediate tubes descending from the trachea and into the lungs
bronchi
bronchi divide into smaller and smaller tubes, eventually becoming these structures
bronchioles
tiny air sacs that sit at the end of the bronchioles, expanding and contracting with the flow of air
alveoli
tiny blood vessels that lie next to the thin tissue membranes of the alveoli
pulmonary capillaries
the space between the right and left lungs, containing the heart, aorta, esophagus, and bronchi
mediastinum
the serous membrane that covers the lobes of the lungs and folds over to line the walls of the thoracic cavity
pleura
the serous membrane lying closest to the lungs and organs
visceral pleura
the serous membrane lining the thoracic cavity
parietal pleura
a fancy word for “breathing in”
inspiration
a fancy word for breathing
pulmonary ventilation
exchange of oxygen and carbon dioxide between the alveoli and the blood in the pulmonary capilaries
external respiration
exchange of oxygen and carbon dioxide between body cells and the blood cells in systematic capiliaries
internal respiration
