- Predict the effect of each of the following conditions on blood flow:(a) vasoconstriction of blood vessels in the skin in response to coldexposure, (b) vasodilation of blood vessels in the skin in response toelevated body temperature, and (c) erythrocytosis, which results in agreatly increased hematocrit.What are the major physiological factors influencing capillary blood flow? What are the major biochemicals released from vascular endothelium that may cause vasoconstriction or vasodilation. How is RAAS system activated in patients with hypertension? What medication can help?What mechanism is most important for short-termregulation of blood pressure under resting conditions?
- According to Poiseuille's Law, vasodilation is associated with increased blood flow. Knowing that capillaries cannot change diameter but arterioles can, how do your observations support this?Parasympathetic stimulation also increases the delay between atrial and ventricular contractions. What is the ionic mechanism?In a standard EPS, briefly explain what is the difference between “pacing after sensing” and “fixed pacing”; in the study of inducibility to ventricular tachycardia (VT)?
- Describe the RAAS mechanism of long-term blood pressure regulation.Write the formula relating flow through an organ to mean arterialpressure and to the resistance to flow that organ offers?The effective-refractory period present during Phase 2 of the actionpotential of ventricular myocytes:A)is relatively long because the Na+ current does not inactivate. B) is relatively long because K+ current is immediately activated once membrane potential becomes positive. C) prevents tetanus in the heart. D) is about twice as long as in skeletal muscle
- Considering the Starling forces (not cardiac Frank-Starling law) affecting fluid movement in a capillary, describe two ways to promote an increase in net fluid movement into the interstitium (i.e. increase/decrease in a given force that is part of calculating net fluid movement)?Epinephrine is released during vigorous exercise. How would epinephrine cause vasoconstriction in the digestive organs but vasodilation in the heart?How does variation in hematocrit influence the hemodynamics of blood flow?
