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.
changing levels of oxygen, carbon dioxide, hydrogen ion and bicarbonate ion in the blood are detected and this visceral sensory information is routed to the hypothalamus and medulla where it stimulates or inhibits the action of components of the respiratory center of the brain.
