Basics
What are the two main phases of one heartbeat?
What is Systolic and Diastolic.
What is heard during S1 and S2?
What is - S1 - lubb and S2 = dupp
What are the two main cardiac pathways?
What is Pulmonary circuit and Systemic circuit.
What are the four chambers of the heart?
What is the - Right Atrium, Right Ventricle, Left Atrium, Left Ventricle
What is an EKG?
What is a test that measures the electrical activity of the heart over a period of time.
What kind of signals make the heart beat?
What is electrical.
What causes the (lub dub) sound in the heart?
What is - the opening and closing of the heart's valves, that can be heard when listening with a stethoscope.
Which cardiac pathway carries blood from the heart to the lungs for oxygenation and back?
What is the Pulmonary Circulation.
What is one thing the pulmonary circuit is responsible for?
What is - Transporting deoxygenated blood from the right side of the heart to the lungs.
What are the five segments of an EKG?
What is P-wave, PR segment, QRS complex. ST segment and the T-wave.
How long does a typical cardiac cycle last?
What is - 800 milli seconds
What do you get when you subtract Systolic pressure from Diastolic Pressure?
What is Pulse Pressure.
Which system do the Cardiac Circulation Pathways work with?
What is the Cardiac Conduction system.
Large veins have *blank* to prevent backflow of blood?
What is - valves
If the SA node stops working, what will take its place?
The AV node
What are the parts of the Cardiac Conduction system?
What is the SA nodes, AV node, bundle of HIS, and Purkinje fibers
If the left side of the heart gets a blockage which cardiac pathway would be affected first?
What is the systemic circulation.
When ventricles contract, the left AV valve prevents blood from flowing from the *blank*.
What is - The left ventricle to the left atrium.
When does Isovolumetric Contraction occur and which valves are open?
What is the QRS complex and none are open.
Why are the walls of the left ventricle thicker than those of the right ventricle?
What is - The left ventricle must force blood into all the capillaries of the lungs.
What artery does the systemic circuit used to transport blood to the rest of the body?
What is the aorta.
The structure that divides the left and right ventricles is called the *blank*.
What is the interventricular septum?
The EKG Wave that results from depolarization of the atria is the?
P Wave
