cardiac cycle and auscultation Flashcards
The heart consists of four chambers, two _____ and two ______. The atria are
completely separated by ___________, whereas the ventricles completely
separated by ____________ septum.
atria, ventricles, interventricular
The ________ circuit involves the right
atrium pumping O2 -poor blood (from the body tissues) into the __________
through an _________ valve known as the __________ valve.
pulmonary, right ventricle, atrioventricular, tricuspid
The ________
then pumps the blood to the lungs for
oxygenation through a _____________
known as the _____________.
right ventricle, lungs, semilunar valve, pulmonary valve
The ________ circuit involves the left
atrium pumping O2 -rich blood (from the
lungs) into the _________ through an
____________ valve known as the
________ valve.
systemic, left atrium, left ventricle, atrioventricular, bicuspid
The __________ then
pumps the blood through a _________
valve, known as the ______ valve, and into
the aorta to be distributed to all the body tissues.
left ventricle, semilunar, aortic
_______ refers to ventricular
relaxation, whereas ________ refers to ventricular contraction.
diastole, systole
The movement of blood through the heart during the cardiac cycle is
controlled by
- Alternating contraction and relaxation of the atrial and ventricular
myocardium. - Opening and closing of valves (which is entirely dependent on the
pressure changes within the heart chambers).
________________is defined as the pressure the blood exerts against any unit area of the blood vessel walls, and it is generally measured in the ________.
Blood pressure (BP), arteries
what are the two BP readings?
- Systolic pressure (pressure in the arteries at the peak of ventricular
contraction). - Diastolic pressure (pressure during ventricular relaxation).
The mathematical difference between systolic pressure and diastolic pressure is called _____________.
pulse pressure
