Respiration (output variables/neural control)

Respiration (Output Variables and Neural Control)

Objectives

Define lung volumes and capacties
Identify lung volumes and capacities on spirogram
Explain how lung volumes can be expressed as a percentage of vital capacity
Define pressure and explain the relation between pressure and volume
Explain how relaxation pressure, maximum inspiratory pressure, and maximum expiratory pressure change with lung volume
Identify the spinal nerves that innervate the diaphragm and external intercostal muscles for inspiration
Identify the parts of the central nervous that control tidal breathing
Explain how afferent information from chemoreceptors and mechanoreceptors affect neural control of tidal breathing
