KROK 1 2007 – Question 199 · KROK (Medicine) · Physiology
Short-term physical activity resulted in reflex amplification of heart rate and raise of systemic arterial pressure. What receptors activation was the main cause of pressor reflex realization?
- A. Proprioreceptors of active muscles
- B. Vascular chemoreceptors
- C. Vascular volume receptors
- D. Hypothalamus thermoreceptors
- E. Vascular baroceptors
Hint
At the start of muscular work the signals that push heart rate and pressure up arise in the working tissue itself, before blood composition has changed.
