Corneille Heymans: Unraveling the Mysteries of Cardiovascular Physiology
Corneille Heymans (28 March 1892 – 18 July 1968) was a Belgian physiologist. He was awarded the Nobel Prize in Physiology or Medicine in 1938.
Life and Career
He was born on 28 March 1892, in Ghent, Flanders, Belgium. He studied medicine at the University of Ghent and completed his Ph.D. in 1920. He then worked at the university as a professor of pharmacology and later as a professor of physiology. His work on the regulation of breathing began in the 1930s and involved experiments on dogs, which led to his discovery of the “reflexogenic zone” in the carotid sinus, a small area in the neck that plays a key role in regulating breathing.
Heymans’ work had important implications for understanding how the body responds to changes in oxygen levels, such as those that occur at high altitudes or during respiratory disease. It also helped pave the way for the development of new treatments for respiratory disorders. In addition to his work on respiratory physiology, Heymans also studied the physiology of the cardiovascular system and the effects of drugs on the body.
From 1945 to 1962 Heymans also lectured at numerous universities in Europe, North and South America, Africa, and Asia. He has been President of the International Union of Physiological Sciences and of the International Council of Pharmacologists and has presided over the 20th International Congress of Physiology held in Brussels in 1956.
He died on 18 July 1968, in Knokke, Flanders, Belgium.
Award and Legacy
He was awarded the Nobel Prize in Physiology or Medicine in 1938, for his work on the regulation of breathing, which led to his discovery of the reflex mechanism that regulates breathing rate and depth. Heymans’ legacy continues to be felt in the field of physiology, particularly in the area of respiratory physiology. His discovery of the reflexogenic zone in the carotid sinus helped pave the way for further research into the mechanisms that regulate breathing, and his work has contributed to the development of new treatments for respiratory disorders.
Heymans’ research on the effects of drugs on the body also had important implications for the field of pharmacology. His work helped to lay the foundation for the development of new drugs and treatments, and his findings continue to influence research in this area today. Overall, Corneille Heymans is remembered as one of the most important physiologists of the 20th century, and his work has had a lasting impact on the field of physiology and medicine.
