Most heart muscle receives blood from more than one artery. This collateral circulation is known as

Which coronary vein drains directly into the right atrium?

The middle cardiac vein drains the area supplied by the posterior Interventricular branch of the right coronary artery. Which chamber(s) is it draining?

What is the correct order for the Aortic Arch, starting with the artery closest to the Ascending Aorta.

Cardiac fibers contain desmosomes and gap junctions, which are part of the intercalated discs. What allows the entire myocardium to contract as a single unit?

The conductive system of the heart is not a nerve tract, it is caused by charged molecules moving across the cell membranes. What molecule slowly leaks out of the cell?

mV is a measurement for membrane potential. What are we measuring when looking at potential energy generated?

What cardiac fiber is the source of electrical activity and self excitable?

The conduction system uses an electrical signal, the message, known as the Action Potential(AP) to eventually make the heart contract. Where does the AP initiate at?

When we hit the threshold of the SA Node Potential. Channels open to allow the fast influx of a molecule, causing rapid depolarization. Which molecule does this?

The conduction system’s Action potential starts at the SA node and flows through 3 internodals. The Anterior Internodal branches off to the L. Atrium. What is the name for this branch?

The conduction system flows from the SA Node to the AV node. It then must go the ventricles through the fibrous skeleton. What is the name of the only branch that runs through the fibrous skeleton?

The velocity of Action Potentials can change depending on where it is in the conduction system. Which part to the conduction system is at 1m/s?

Action Potential in Contractile Fibers goes through phases 0-4. During which phase does the K efflux balance with Ca influx causing the cell to begin contraction?

Throughout the contractile fibers phases, another action potential cannot occurs normally. This is called?

The fluid that makes up the cytosol also makes up 2/3 of your bodily fluid. This fluid is know as?

Water moves to where across a selectively permeable membrane to where the solute concentration is the highest. This is know as?

The involuntary nervous system, also know as the autonomic nervous system(ANS) is what allows your heart to beat without your input. It has 2 nervous systems included in it. The nervous system which controls your flight or fight response, is known as?

A feature of the heart which includes pectinate muscle and described as a pouch-like structure is known as?

The blood flows throughout the systemic and pulmonary systems of the body. The blood flows from the lungs and enters the Left Atrium via the _____

During neonatal circulation, the ductus arteriosus loses it valve ability and becomes the ligamentum arteriosum. The ductus arteriosus help bypass the lungs via connecting which valves?

The Atrioventricular Valves are closed by pressure, the contraction of the ventricles causes the blood pressure to rise. This rise in pressure forces the blood out of the semilunar valves. What prevents eversion?

The heart has its own blood supply with coronary arteries and veins. The Anterior Interventricular Branch lies in the interventricular sulcus and supplies a bulk of the blood to the left verntricle. What coronary vein drains this area?

The SA Node is known as the natural pacemaker, but it can be altered depending if you are at rest or in motion. If you are out running, the SA Node increases Action Potentials by which nervous system sending hormones to the SA node?

The Sinoatrial Node is located in the R. Atrium wall, lateral to the opening of the Superior Vena Cava. Which layer of the heart is it embedded in?

What represents the P wave?

What does the QRS complex represent?

What part of an ECG represents the ventricular repolarization?

Which side of the heart has a considerably higher pressure during contraction?

When both AV and SL valves are closed at the same time is known as

Which valve has the highest afterload?

If a person has a EDV of 150mL and an ESV of 100mL, with a heart rate of 60bpm, what is their Cardiac Output?

Which heart sound is the closure offer the SL valves?

Which factor for regulating the ventricles pump at the same times is known as the degree of stretch of the heart before contraction?
