Name the 4 chambers of the heart, and where they receive blood from:

Name the 3 muscle layers of the heart, give an example of where you would find these:

Name the 2 AV Valves (Atrioventricular) and the 2 SV Valves (semilunar). Valves keep blood flowing in one direction, keeping blood in one chamber until the next chamber is ready.

The first heart sound is known as the ______________ and the ( lub OR dub )

The second heart sound is known as the _______________ and the ( lub OR dub )

What arteries are responsible for supplying blood to the heart?

Coronary veins return blood to the right atrium through what?

The conduction system is also know as the __________________ circuit.

List the 4 main components of the Conduction system, in order:

Which of thse is known for being the pacemaker of the heart, initiates the eletrical impulse, stimulates contraction of the atrium, sends signal to the AV Node, generates 60-100 impulses/minute, and seen on ECG as P wave? * Atrioventricular Node (AV Node)

* Bundle of HIS
* Purkinje Fibers
* Sinoatrial Node (SA Node)

Which of thse is known for having terminal ends of the left and right bundle branches, when impulses reach here it signals ventricles to contract, forms the QRS complex on ECG, and it can generate 20-40 impulses/min if SA & AV nodes fail? * Atrioventricular Node (AV Node)

* Bundle of HIS
* Purkinje Fibers
* Sinoatrial Node (SA Node)

Which of thse is known for having the impulses divided into the right and left bundle branches, the bundle branches terminate at the Purkinje fibers, the left branch stimulates the left ventricle and the right branch stimulates the right ventricle? * Atrioventricular Node (AV Node)

* Bundle of HIS
* Purkinje Fibers
* Sinoatrial Node (SA Node)

Which of thse is known for having a delay in transmission of impulse at this point, is important to allow atria to empty before ventricles contract, the impulse is sent through the Bundle of HIS, the delay forms most of the PR segment, and it can generate 40-60 impluses/minute? * Atrioventricular Node (AV Node)

* Bundle of HIS
* Purkinje Fibers
* Sinoatrial Node (SA Node)

In the conduction system, what is it when there is stimulation of the cardiac cells causing contractions, in which they release their energy? * Repolarization
* Depolarization

In the conduction system, what is the resting state of the cardiac cells, their energy is restored, it is represented in the T wave, atrial ______ occurs but is hidden in the QRS complex. * Repolarization

* Depolarization

Controls of the Heart: What nervous system has the Sympathetic and Parasympathetic Fibers?

Controls of the Heart: What do the Sympathetic and Parasympathetic Fibers do?

Controls of the Heart: When stimulated the Sympathetic Fibers will (1) _____________ heart rate, (2) speeds conduction through _____ node, (3) strengthens _____________________ of the heart.

Controls of the Heart: When stimulated the Parasympathetic Fibers will (1) _______________ heart rate, (2) slows conduction through _____ node, (3) decreases strength of the ______________.

Cardiac Function: The primary function is to pump blood through the (1) _________ & (2) __________ circulation. There is a continuous pattern of (3) ___________ & (4) ____________.

In Cardiac Function: This is the ability of the muscle fibers to produce a contraction. * Cardiac Cycle
* Stroke Volume
* Cardiac Output
* Preload
* Contractility
* Afterload

In Cardiac Function: This is the amount of blood pumped out of 1 ventricle with each beat of the heart. * Cardiac Cycle
* Stroke Volume
* Cardiac Output
* Preload
* Contractility
* Afterload

In Cardiac Function: Contraction +...
