Lab # 3 Respiratory system Flashcards
What is the equation for Minute ventilation
(#resperations/Min) x Tidal Volume
What is the equation for alveolar ventilation
(#resperations/Min) x (Tidal Volume-(Weight x 2.2))
What is tidal volume
Tidal volume is the amount of air that moves in and out of the lungs during normal respiration
What is Expiratory Reserve volume
the amount of air that one can expire beyond the tidal volume
What is the vital capacity
it is when a person takes in as deep of a breath as possible and breaths out as much air as they can so from the top of the inspiratory reserve to the bottom of the expiratory reserve
Inspiratory reserve volume
The amount of air that one can inspire beyond the tidal volume
what is minute ventilation
the amount of tidal volume that passes in and out of the lungs in one minute
What is alveolar ventilation
it is like minute ventilation but it allows you to determine the amount of new air that reaches the alveoli because it takes into account the anatomical dead space of the body
Forced Expiratory volume
the percentage of air that a person can expel in one second of breathing out
what is the equation for forced expiratory volume
(Volume of air expelled in 1 second / total volume of air expelled) x 100
remember that you take a breath in first so total air expelled would be the vital capacity
What are the three layers of the trachea
Mucosa which is the layer closest to the lumen and contains goblet cells
The submucosa second layer down made of connective tissue
Adventitia contains the hyaline cartilage and the smooth muscle
What kind of tissue is the mucosa layer
Ciliated pseudostratified columnar epithelium
Label the pharynx epiglottis glottis trachea bronchi bronchioles alveoli
