BIO 305 Lab Final Exam With Complete Solutions 100% Verified
What can be said to be complete when the cells of the atria are completely deploarized?
P wave is complete
QRS has not begun
What must you know to calculate MAP?
systolic pressure and the diastolic pressure
What are the two divisions of the respiratory cycle?
inspiration (inhalation) and expiration (exhalation)
air flows from outside of the body into the lungs
inspiration (inhalation)
air flows from inside of the lungs to the outside of the body
expiration (exhalation)
measurements that help is understand lung function
respiratory parameters
What are the categories that the respiratory parameters can be broken down into?
volumes and capacities
discrete amounts of air
usually associated with direction
,volumes
an amount of air consisting of 2 or more volumes
still a volume; a set amount of air
capacities
how are respiratory parameters measured?
spirometry
amount of air inspired or expired at any activity level
tidal volume
additional amount of air that can be inspired after a resting inspiration
edge of tidal volume up to max possible inspiration
inspiratory reserve volume (IRV)
graphic of respiratory volumes
additional amount of air that can be expired after a resting expiration
expiratory reserve volume (ERV)
amount of air remaining in lungs after maximal expiration
after ERV and still some air in the lungs
residual volume (RV)
, total amount of air that can be expired after maximal inspiration
TV + IRV + ERV
vital capacity (VC)
TV + IRV
inspiratory capacity (IC)
capacities diagram
ERV + RV
functional residual capacity
TV + IRV + ERV + RV
total lung capacity (TLC)
the volume of air breathed per unit of time
TV (mL/breath) X Respiratory frequency (breaths/min)
minute ventilation
volume of air, breathed per unit of time, used in gas exchange
alveolar ventilation
