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.
Â­CO detectors can use several types of sensors to sense carbon monoxide in the air. Biomimetic sensor technology reproduces CO's effects on hemoglobin in the blood. In a biomimetic sensor, a gel changes color as it absorbs CO.
