Flashcards in Chapter 12: Respiratory System: Lungs and Breathing Deck (28):
Animal gas exchange organs of breathing.
Lung-enclosing serous membranes that serve to reduce friction between lungs and associated body cavity walls.
Volume within animals containing the lungs.
Exchange by animals of gasses with those in the air as mediated by active flow of air over specialized body tissues.
Uptake of oxygen from and release of carbon dioxide to the environment by an organism.
Uptake of oxygen and release of carbon dioxide within the body.
Somewhat external air handling anatomy including the external nose, the associated nasal cavity, and the pharynx.
Upper respiratory tract
Anatomy associated with the warming, filtering, and moistening of air in the course of inhalation.
The internal volume found behind the external nose.
Volumes that are found within aspects of bodies, particularly air-filled spaces within bones.
The back of the mouth and nose, also known as the throat
Larynx, trachea, bronchi, bronchioles, and alveoles.
Lower respiratory tract
Post-pharynx cartilaginous connector to the trachea that includes the epiglottis, glottis, and vocal cords.
Flap responsible for sealing the larynx during swallowing so that passage of food or water into the trachea may be avoided.
Connective tissue associated with the larynx that serves to impart vibrations on air especially during exhalation.
Cartilage reinforced, collapse-resistant passageway from larynx to lungs.
Large tubes through which air passes within lungs.
Smaller tubes through which air passes within the lungs.
Microscopic pouches within lungs where majority of gas exchange occurs.
Collections of microscopic pouches responsible for majority of gas exchange within lungs.
Molecule that can simultaneously dissolve in both water and lipids, potentially resulting in suspension of the latter in the former.
Blood vessels that supply unoxygenated blood to the lungs.
Blood vessels that supply oxygenated blood to the heart.
Means by which the rib cage is moved upward to effect inhalation.
Means by which the thoracic cavity expands towards the abdominal cavity to effect inhalation.
Amount of air entering the lungs per each inhalation or exiting the lungs per each exhalation under normal unforced conditions.
Volume of air that is the difference between fully inflated lungs via inhalation and fully deflated lungs via exhalation.
