How does blood flow through the pulmonary valve? ANSWER Blood flows from the right
ventricle, to the pulmonary arteries
Heart valves on the left side of the heart ANSWER Aortic valve, mitral valve
How does blood flow through the mitral valve? - ANSWER Blood flows from the left
atrium into the left ventricle
How does blood flow through the aortic valve? - ANSWER Blood flows from the left
ventricle into the aortic arch
What does S1 sound like? What is happening in heart? -ANSWER S1 is the first heart
sound heard-the "lub" in "lub-dub". The sound is caused by the closure of the mitral and

What is the name of this sound of S3? What is happening to the heart? - ANSWER The S3
is an extra heart sound, also known as a gallop. It can be heard directly after S2 and can
indicate atrial or mitral regurgitation, left ventricular heart failure, or volume overload.
,What does S4 sound like? What is happening in the heart? -ANSWER S4 is an extra heart
sound, called a gallop. It occurs before S1 and signifies HTN, acute MI, aortic stenosis,
pulmonary stenosis, pulmonary HTN
What are types of coronary ischemia? - ANSWER Stable angina, unstable angina and
