cardiovascular system
-
neural control mechanism
-
-
-
chemoreceptors - found in the carotid arteries/aortic arch that detect changes in blood acidity (increase acidity = increase HR)
baroreceptors - found in aortic arch, carotid sinus, heart and blood vessels that responds to increase blood pressure which increases or decrease HR
proprioceptors - sensory nerve endings in muscle tendons/joints that detect changes in muscle movement (increase muscle movement = increase heart rate)
-
cardiac cycle
-
atrial systole - impulse from SAN, synchronous atrial contraction, active filling of ventricles
ventricular diastole - impulse from SAN, synchronous atrial contraction, filling of ventricles
ventricular systole - semilunar valves, emptying of ventricle
