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.
The central chemoreceptors do not directly detect the arterial CO2 tension. Instead, they detect decreases in the CSF pH. These two values are connected because arterial CO2 diffuses past the blood brain barrier, into the CSF, and is converted by carbonic anhydrase to carbonic acid that in turn decreases the CSF pH.
