Term
pharynx
Definition
funnel shaped structure that connects the nose and mouth to the larynx, has 3 divisions: nasopharynx, oropharynx, laryngopharynx
Term
nasopharynx
Definition
portion of the pharynx that is posterior to the nose and is the most superior aspect of the pharynx
Term
oropharynx
Definition
division of the pharynx that contains plantine tonsils and lingual tonsils
Term
larynx
Definition
used for speech and serves as a filtering device for digestive and respiratory tracts
Term
carina
Definition
area where the trachea divides into left and right mainstem bronchi, right mainstem bronchis is almost a straight continuation of the trachea, left angles more acutely to the left
Term
bronchioles
Definition
a further division of the bronchi
Term
alveolar ducts
Definition
a further division of the bronchioles
Term
alveoli
Definition
a further division of the alveolar ducts where most of the gas exchange takes place
Term
pulmonary cappilaries
Definition
lie in close proximity to the alveoli and assist blood movement in gas exchange
Term
surfactant
Definition
chemical that keeps the alveoli moistened and open
Term
right lung
Definition
has three main lobes and is covered by pleura
Term
left lung
Definition
has 2 main lobes and is covered by pleura
Term
visceral pleura
Definition
covers the lungs and does not contain nerve fibers
Term
parietal pleura
Definition
lines the thoracic cavity and contains nerve fibers
Term
pleural fluid
Definition
fluid found in the pleural space that serves as a lubricant for lung movement during respiration
Term
pulmonary arteries
Definition
transport deoxygenated blood from the heart and present it to the lungs for oxygenation
Term
bronchial arteries
Definition
arteries that branch from the aorta that supply blood to the lungs
Term
ventilation
Definition
the mechanical process of moving air in and out of the lungs, has 2 phases: inspiration and expiration
Term
diaphraghm
Definition
dome-shaped muscle that seperates the thorax and the abdomen
Term
bronchospasm
Definition
widespread constriction of the bronchial smooth muscle
Term
500 ml
Definition
amount of air that moves in and out of the lungs during normal respiration
Term
minute respiration volume
Definition
the amount of air moved in and out of the lungs in one minute
Term
medulla
Definition
lower portion of the brain stem that controls ventilation
Term
diffusion
Definition
the process by which gases move between alveoli and the pulmonary cappilaries
Term
perfusion
Definition
the circulation of oxygen rich blood throughout the body
Term
hemoglobin
Definition
transport protein that carries oxygen in the blood
Term
oxyhemoglobin
Definition
oxygen attached hemoglobin
Term
deoxyhemoglobin
Definition
hemoglobin without oxygen
Term
respiration
Definition
the exchange of gases between a living organism and their environment
Term
hypoxia
Definition
a state of insufficient oxygen
Term
pulmonary embolism
Definition
a blockage of a division of the pulmonary artery by a clot
