Question | Answer |
---|---|
what is pressure of blood exerted on vessel walls measured with | sphyogomanometer |
what is this called durning ventricular contraction | arterial systolic pressure |
what is think called durning ventricular relaxation | arterial diastolic pressure |
what is the amount of blood going into aorta per minute | cardiac output |
what is stroke volume X beats per min | cardiac output |
what is friction between blood and vessel walls influenced by vessel elasticity | peripheral resistance |
what are nerve endings that detect changes in blood pressure | baroreceptors |
where are baroreceptors found | aorta, carotid, r.atrium |
what is vessels carring blood from heart to lungs back to heart | pulmonary circulation |
what is out of left ventricular, throughout the body, back to the r. atrium | systemic circulation |
junction between pulmonary artery and aorta | ductus arteriosus |
what is junction b/w l and r atria, some blood bypasses lungs | foramen ovale |
what bypasses the liver | ductus venosus |
what is high o2 | umbilical artery |
what is low o2 | umbilical vein |
acculmulatioin of fatty materials beneth inner lining of arteies. plaque = deposit | atherosclerosis |
pain un the left arm from lack of oxygen to the myocardium | angina |
dead heart tissue from a heart attack | myocardial infarction |
high blood pressure | hypertension |
obstruction of a coronary artery is bypassed with a vein from the leg ot the sternum area | coronary bypass |
long thin tube with a small ballonon the end is indserted at the point of blocage | angioplasty |
biscuspid valvue is not in sync with the rest of the heart | mitral valve prolapse |
arteries in the brain become blocked | stroke |
abnormal sound durning heart beat, often from a valve disorder | heart murmur |
heart cant supply oxygen cuz one side fails. blood may build up in the lungs or body | congestive heart failure |
