Slide 24 тря Imgm and Blood vessel blood viscocity increases then bp w ingraxes 6. Fill in the following chart. 5. BP- CO total blood veur Receptors Control Center Effectors If blood vessel diameter increases then bp decreases Short Term Blood Pressure Regulation 1. Bororeceptors Chemorceptors Hypothalamus (higher brain centers) Vasuclar smooth muscle 2 vasomotor tone 1. 7. Fill in the following chart. Blood viscosity The three factors that can alter TPR are diconeter if co increases then Bp increases. If intoso. If total blood vessel length increases then bp Direct Mechanism Long Term Blood Pressure Regulation Describe: When blood pressure is high, the amount of filtration of fluid.... 2 Indirect Mechanism Name the 4 hormones and their effects 1. Renin converts the plasma protien ongiotensinogen to ông. I which in turn is converted, to converted to 2. Angiotensin 11 constricts blood vessels throug 3. Aldosterone 4. ADH Photos forder Exam 2 8 Explain what hydrostatic pressure is caused by and in what direction does it cause a movement in the capillaries? Hydrostatic pressure is the force that is created by standing or resting water it causes movement out of the capillaries. 9. Explain what colloid osmotic or oncotic pressure is caused by and in what direction does it cause a movement in the capillaries? Colloid... is created by nondiffusable plasma protiens in the blood stream, which draw water to word themselves. Fill in increase or decrease in the boxes below: from e of the

Complete the following phases of the cardiac cycle chart: Phase AV Semilunar Pressure in valves valves ventricles Closed A. Ventricular Open Filling (Mid to late diastole) B. Ventricular Closed Systole (Isovolumetric contraction) C. Ventricular systole (Ventricular ejection) Closed Closed Low D. Early Diastole (Isovolumetric CIOS closed relaxation) hign lopen high high 11. Lub sounds result from closing of the AV contraction of the ventricle semilunar ventricles. Blood moving Blood enters atria and flows into ventricles Blood doesn't move Blood enters into corta Blood doesnt move Heart sounds None. valves. These valves close from 5, None 52 valves. These valves close from Dub sounds result from closing of the of the
