14492503729 | Local control | -autoregulation -myogenic control -metabolic control -angiogenisis | 0 | |
14492510265 | neural control | Vasomotor center in medulla Sympathetic impulses cause vasoconstriction or vasodialation Regulated by autonomic reflexes: -Bareoflex -Chemoreflex -Medullary ischemic reflex | 1 | |
14492513230 | Bareoflex | -negative feedback mechanism -inhibits SNS Effects: -reduced HR -Reduced CO -dialate vessel -reduce BP | 2 | |
14492517173 | chemoreflex | Response to chemical changes Chemoreceptors ↓pH, ↓O2, ↑CO2 Primary role: -Adjust respiration Secondary role: -Vasomotor -Increases perfusion | ![]() | 3 |
14492520331 | medullary ischemic reflex | automatic response to a drop in perfusion of the brain -cardiac and vasomotor centers -increase HR and contraction -input from higher brain stems | 4 | |
14492523151 | Chemical control | hormones act on vascular smooth muscle | 5 | |
14492524018 | chemical control hormones: | Angiotensin II, Aldosterone, Atrial natriuretic peptide, Antidiuretic hormone, Epinephrine and norepinephrine | 6 | |
14492526151 | Angiotesin II | vasoconstriction | 7 | |
14492527607 | Aldosterone | NA retention by kidneys | 8 | |
14492528232 | atrial netriuretic peptide | increase Na excretion | 9 | |
14492529121 | antidiuretic hormone | H20 retention | 10 | |
14492529847 | epinepherine and norepinepherine | -vasoconstriction in most vessels -vasodialation in coronary and skeletal muscle blood vessels | 11 |
