Role of Chemoreceptors in the Zone of Vertebral Arteries in the Formation of the Cardiorespiratory Functional System
2009
Agadjanyin, N. A | Kupriyanov, S. V
Chemoreceptors in refl exogenic zones of the vertebral and carotid arteries play a regulatory role in the cardiorespiratory interaction. Perfusion of these zones with lactic acid solution (0.5-3.0 mmol/liter) produced a refl ex response, which was manifested in stimulation of external respiration and increase in systemic blood pressure. The refl ex response of these systems was opposite after local administration of 0.3 M Tris-buffer. Correlation analysis revealed the role of afferentation from refl exogenic zones in the formation of a regulatory functional system for tissue gas exchange and acid-base balance.
