Flashcards in Respiratory Deck (27):
Branch of a respiratory bronchiole around which alveolar sacs are emptied
Highly phagocytic cell found in the alveolar walls of the lungs. Also called a dust cell
A cluster of alveoli that share a common opening.
A small hollow or cavity; an air sac in the lungs; milk-secreting portions of a mammary gland.
Neuron capable of responding to changes in blood, air or fluid pressure
The trachea, bronchi, and their branching structures up to and including the terminal bronchioles
Branch of a tertiary bronchus further dividing into terminal bronchioles( distributed to lobules of the lung), which divide into respiratory bronchioles (distributed to alveolar sacs)
Sensory receptor that detects the presence of a specific chemical
A large, leaf-shaped piece of cartilage lying on top of the larynx, attached to the thyroid cartilage; it's attached portion is free to move up and down to cover the glottis (vocal folds and rima glottidis) during swallowing
Breathing out; expelling air from the lungs into the atmosphere
The exchange of respiratory gases between the lungs and blood
Lack of oxygen at the tissue level
The act of drawing air into the lungs. Also called inspiration
The inferior portion of the pharynx, extending downward from the level of the hyoid bone that divides posteriorly into the esophagus and anteriorly into the larynx. Also hypopharynx
The exchange of respiratory gases between blood and body cells. Also called tissue respiration or systemic gas exchange.
The voice box, a short passage that connects the pharynx with the trachea.
The neurons of the respiratory center in the medulla oblongata that consist of dorsal respiratory group that is active during normal quiet breathing and the ventral respiratory group that is active during forceful
Medullary respiratory center
The superior portion of the pharynx, lying posterior to the nose and extending inferiorly to the soft palate.
The intermediate portion of the pharynx, lying posterior to the mouth and extending from the soft palate to the hyoid bone.
Hemoglobin combined with oxygen
The throat: a tube that starts at the internal nares and runs partway down the neck, where it opens into the esophagus posteriorly and the larynx anteriorly.
Small potential space between the visceral and parietal pleurae
The inflow (inhalation) and outflow (exhalation) of air between the atmosphere and the lungs. Also called breathing
Complex mixture of phospholipids and lipoproteins, produced by type II alveolar (septal) cells in the lungs, that decreases surface tension
Tubular air passageway extending from the larynx to the fifth thoracic vertebra. Also called windpipe
Pair of mucous membrane folds below the ventricular folds that function in voice production
