Explore the final part of a comprehensive lecture series on the regulation of breathing, focusing on factors that influence respiratory rate and depth. Delve into key concepts such as stretch receptors, the Hering-Breuer reflex, irritant receptors, juxtacapillary receptors, proprioreceptors, and the roles of the fasciculus, hypothalamus, and cortex in breathing regulation. Led by Professor Zach Murphy, this 24-minute video provides an in-depth examination of these crucial respiratory mechanisms, offering valuable insights for students and professionals in the field of respiratory physiology.
