Interactive Physiology Worksheet:
Cardiovascular System: Cardiac Cycle differences of blood pressure
1. Valves open in response to ______________________________________ on their two sides.
2. List the chambers/vessels that the four valves connect:
Chamber
Right ventricle
Left ventricle
Valve
Pulmonary semilunar
Aortic semilunar
Chamber/Vessel
Pulmonary trunk
Aorta
Left atrium
Mitral
Left ventricle
Right atrium
Tricuspid
Right ventricle
mid to late diastole 3. a. Ventricular filling occurs during ________________________ ventricular ________________. av valves atrioventricular b. Blood flows through the ____________________, or __________, valves into the ventricles.
4. During ventricular …show more content…
During isovolumetric relaxation, what closes the semilunar valves?
_____________________________________________________________________________
blood flow back toward the heart due to aortic pressure being greater than interventriuclar pressure
7. During isovolumetric relaxation, what opens the AV valves? atrial pressure is greater than interventricular pressure
_____________________________________________________________________________
8. Why is hypertension hard on the heart? ventricular pressure must rise higher to open the semilunar valves; the same increase in a normal BP, less
_______________________________________________________________________________
blood is ejected in a hypertensive case so the heart with hypertension must work harder to eject the same
_______________________________________________________________________________ SV
