BIOL 3310 Lecture Notes - Lecture 7: Portal Vein, Vasomotor Center, Anastomosis
Document Summary
Decreased bp initiation barore ex and angiotensin ii to stimulate vasoconstriction - low bp causes fainting, person in horizontal spot has gravity restore ow. Examples of chemore exes hypoxemia, hypercarbia (too much co2), and acidosis stimulate chemoreceptors - instruct vasomotor center to cause constriction, which bp, lung perfusion and atulency commutation. Secondary high blood pressure hypertension caused by another disease - ex: kidney failure. Pulse pressure value of systolic pressure - diastolic important mensuration of stress exerted on small arteries. Pressure slope - thoracic pump - skeletal muscle pump - gravity. Venous anastomosis when ii veins merge most common anastomosis provides alternate routes for drain. Example of portal vein scheme (circulation) hypothalamus - anterior pituitary found in kidneys small bowel - liver. Septic daze when bacterial toxins gun trigger vasodilation and increase capillary permeability. Sphygmomamometer beat blood pressure at brachial artery of weapon system - value is systolic over diastolic.
