Study Notes
Chemoreceptors and Respiratory Control
Central Chemoreceptors
- Located in the medulla oblongata, in the ventrolateral surface
- Respond to changes in CO2 and H+ levels in the cerebrospinal fluid (CSF)
- Play a crucial role in the chemical control of respiration
Peripheral Chemoreceptors
- Located in the aortic and carotid bodies
- Respond to changes in O2, CO2, and H+ levels in the blood
- Stimulated by low O2 levels, high CO2 levels, and high H+ levels in the blood
- Send signals to the respiratory centers to increase breathing rate
Respiratory Centers
- Located in the brainstem
- Responsible for generating the basic rhythm of respiration
- Regulate breathing rate and depth in response to changes in CO2, O2, and H+ levels
Functions
- The respiratory centers control the contraction and relaxation of the diaphragm and intercostal muscles
- The chemoreceptors play a crucial role in the chemical control of respiration, adjusting breathing rate and depth to maintain homeostasis
