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.
This potential is a linear function of the hydrogen concentration in the solution, which allows quantitative measurements to be made. Figure 1 shows a pH meter measurement setup with two separate sensors, a pH sensor and a reference sensor is shown. Nowadays, ph meters merge the two separate sensors into one electrode.
