The Walker Art Center is home to an in-depth collection of Oldenburgâs work, ranging from early performance-related objects to large-scale outdoor sculpture to drawings, prints, multiples, and rare studies.
Chemoreceptors detect the levels of carbon dioxide in the blood by monitoring the concentrations of hydrogen ions in the blood. Learning Objective. Describe the role of chemoreceptors in the regulation of breathing. An increase in carbon dioxide concentration leads to a decrease in the pH of blood due to the production of H+ ions from carbonic acid.
Arterial chemoreceptors include the carotid and aortic bodies, which are small organs with a very high blood flow. Glomus cells in the arterial chemoreceptors sense changes in arterial P O2, P CO2, and pH by mechanisms involving ion channels and heme-containing molecules.Decreased P O2 and pH, and increased P CO2, depolarize glomus cells and trigger the release of neurotransmitters.rterial chemoreceptors respond to changes in arterial P O2, P CO2, and pH and evoke negative feedback reflexes in the respiratory and cardiovascular systems to maintain blood gas homeostasis.
