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.
Chemoreceptors that regulate the depth and rhythm of breathing are broken down into two categories. 1  central chemoreceptors are located on the ventrolateral surface of medulla oblongata and detect changes in pH of cerebrospinal fluid. 2  peripheral chemoreceptors: consists of aortic and carotid bodies. Examples of distance chemoreceptors are: 2  olfactory receptor neurons in the olfactory system: Olfaction involves the ability to detect chemicals in the gaseous state. 3  In vertebrates, the olfactory system detects odorants and pheromones in the nasal cavity.
