Ventilation is a result of skeletal muscle contraction When the diaphragm contracts, the volume in thoracic cavity increases What is inspiration? increase in thoracic volume reduces pressure in thoracic cavity, allowing atmospheric gas to enter lungs What is expiration? as diaphragm relaxes, pressure in thoracic cavity increases as volume decreases, forcing air out of lungs What is pulmonary minute ventilation? amount of air that flows into and out of lungs in 1 minute What is the rate of n...

What is ventilation? inspiration (acquiring oxygen) and expiring (removing co2) Describe the different measures of ventilation. - tidal volume (tv)--volume of air going in and out at rest - vital capacity (vc)--maximal amount of air that can deliberately be moved in or out of lungs with forced inhalation and exhalation - forced vital capacity (fvc)--maximal amount of air that is exhaled from lungs during forced exhalation - forced expiratory volume in 1 second (fev1)--maximal amount of...
