13. Blood pressure and Cardiac output control Things to use 1) HR- chronotropic state 2) EDV- increase increase in SV 3) (E- Beta1, ACh- m2AChR) Inotropic State- increase contractility increase SV 4) TPR increase diastolic blood pressure increase afterload increase preload increase SR 5) Blood volume capacitance vessels--> veins I. Control Systems a. Stretch receptors i. Main in atrial walls ii. Atrial stretch (vagal afferents) (+) Medulla (cardiovascular control center +/- sympathetic/parasympathetic increase HR 1. Banbridge reflex b. Baroreceptors- pressure sensors i. Located on carotid sinus and aortic arch 1. Carotid sinus herring nerve Cranial IX afferents 2. Aortic Arch vagal afferents 3. Both to the medulla ii. Medulla (-) parasympathetic (-) chronotropic (+) CO iii. Medulla (+)sympathetic (+) chronotropic and (-) inotropic (+) both CO iv. Sympathetic (+)venous return and TPR (+) MAP (+) baroreceptors
