Respiratory Volumes and Capacities Quiz

Lung volume represents a single volume of air into the lungs, while lung capacity represents 2 or more volumes added together. Examples of lung volumes include tidal volume and residual volume, while examples of lung capacities include functional residual capacity and inspiratory capacity.

A restrictive pattern of respiratory disease is characterized by an overall reduction of volumes and capacities, along with inflation problems and decreased compliance. Examples include pulmonary fibrosis, kyphosis, and severe burns.

An obstructive pattern of respiratory disease is characterized by an overall increase of volumes and capacities, along with airflow problems due to narrowing or collapse that limits airflow. Examples include COPD (chronic obstructive pulmonary disorder) and asthma.

<p>In the context of respiratory physiology, TI (inspiratory time) and TE (expiratory time) contribute to the I:E ratio, which represents the ratio of time spent inhaling to time spent exhaling during each breath.</p> Signup and view all the answers

<p>Vital capacity refers to the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is the sum of the tidal volume, inspiratory reserve volume, and expiratory reserve volume.</p> Signup and view all the answers
