ANATOMY CHAPTER 13.5 blood vessels
| 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 |
