BIOC34H3 Lecture Notes - Lecture 3: Spirometry, Chronic Obstructive Pulmonary Disease, Lung Volumes
Document Summary
Activity 1: measuring respiratory volumes and calculating capacities. Provide the data recorded from the experiments in this section (i. e. , chart 1). Activity 2: comparative spirometry provide the data recorded from the experiments in this section (i. e. , chart 2). Activity 3: effect of surfactant and intrapleural pressure on respiration provide the data recorded from the experiments in this section (i. e. , chart 3). During vigorous exercise, the body must compensate for the increased oxygen demand. The total volume in the lung is increased during exercise. It is composed of the sum of four components that include the tidal volume, residual volume, irv, and erv. Vigorous exercise leads to an increase tidal volume because the volume of the breath corresponds to the increased breathing frequency, helping to obtain more air to participate in alveolar ventilation and increase oxygenation of the blood. Increasing tidal volume comes with a few consequences.
