More than 100 scientists from 14 different countries will meet in Park City through Sept. 3 for the Ninth International Symposium on Arterial Chemoreceptors.
The meeting, held once every three years, is being conducted for the first time in the United States and is being hosted by the University of Utah School of Medicine.Arterial chemoreceptors are specialized biological tissues found in the body's major arteries that detect changes in oxygen and carbon dioxide in the blood and then signal this information to the brain through the nervous system. The brain then adjusts heart rate, respiration and blood pressure to bring blood levels of these gases back into normal ranges.
Arterial chemoreceptors are important in helping the body to adjust to the stresses of physical exercise and high altitude, the scientists explained. Persons with subnormal arterial chemoreceptors are at risk under those conditions.
Scientists also think that abnormal chemoreceptors may play a role in hypertension and Sudden Infant Death Syndrome.
Dr. Salvatore Fidone, professor of physiology, and Dr. Carlos Eyzaguirre, professor and former chairman of the U.'s physiology department, organized the symposium.
