Peripheral chemoreceptors
WebJun 8, 2015 · Mechanoreceptors in the lung monitor mechanical forces acting on lung tissue. Specifically, they stimulate respiratory activity where the lung is deflated, and depress it when the tissues are overstretched. This reflex was discovered by Ewald Hering and Joseph Breuer in 1868. WebJan 17, 2024 · Additionally, the peripheral chemoreceptors cause sympathetic nervous system stimulation, which causes the heart rate to increase while stroke volume decreases, and digestion is impaired. Shortness of breath is common, and urination increases.

WebThe peripheral chemoreceptors are directly exposed to arterial blood and are capable of responding to changes in CO 2, O 2, and pH. There are two populations of chemoreceptive cells in the vasculature (see figure 17.4). One population is found in the aortic arch and is referred to as the aortic bodies.

WebMay 14, 2007 · Arterial chemoreceptors serve an important regulatory role in the control of alveolar ventilation, but they also exert a powerful influence on cardiovascular function. 9 Activation of arterial chemoreceptors by hypoxemia increases sympathetic outflow to systemic vascular beds to compensate for the direct vasodilating effects of hypoxia on … Peripheral chemoreceptors (of the carotid and aortic bodies) are so named because they are sensory extensions of the peripheral nervous system into blood vessels where they detect changes in chemical concentrations. As transducers of patterns of variability in the surrounding environment, carotid and aortic … See more Both carotid bodies and aortic bodies increase sensory discharge during hypoxia. Carotid bodies are considered the primary peripheral chemoreceptor and have been shown to contribute more to a hypoxic response. … See more • Central chemoreceptors • Chemoreceptors • Control of respiration See more Signal transduction Peripheral chemoreceptors were identified as necessary to breathing regulation much sooner than their mechanisms for acquiring information from the bloodstream were beginning to be understood.
