On an EGK, the spikes and dips in the line tracings are called waves.

A muscular organ that pumps the blood throughout the circulatory system.

Where is the location of the Heart?

A result of physical training that affects the heart muscles that causes additional proteins such as myosin or actin.

Also known as the Mitral Valve.

The only artery in the human body that carries deoxygenated blood away from the heart.

The function of the valve is to prevent back flow of blood into the right atrium.

The Left side of the heart consists of all the following EXCEPT:

The inner layer of the heart is known as:

Thin double-layered sac which encloses and covers the heart.

An enlarged heart is known as Cardiomegaly.

A common cause of sudden cardiac arrest in young people, including young athletes.

Inflammation of the heart muscle is known as:

Affects the inner lining of the heart chambers and valves and severely damages the function of the heart.

Cardiac Output is defined as:

What divides the heart into right and left sides?

The Atrioventricular Valves consist of:

This is seen when the flaps of the valve flop or bulge back into an opposite direction during a heartbeat.

All of the following are causes of Coronary Artery Disease EXCEPT:

Chest pain due to lack of oxygenated blood.

Occurs if the flaps of a valve thickens, stiffens, or fuses together.

Hole in the interatrial septum of then heart.

All of the following are symptoms of Coronary Heart Disease EXCEPT:

Hardening and narrowing of the arteries

The primary structural proteins of cardiac muscle are myosin and actin.

The amount of blood that is pumped or ejected from one ventricle of the heart during each heart beat.

A brief change in voltage across the cell membrane of heart cells.

Cardiac muscle cells are typically branch-like instead of linear.

Frequency of heart rate (bradycardia or tachycardia)

Carries the contraction impulse from both the left and right bundle branches to the myocardium of the ventricles.

The Gate Keeper?

Functions as a cardio-inhibitory center and decreases the heart rate and stroke volume that affects the cardiac output.

The ability of the heart to conduct impulses from SA node to AV node, to Bundle of His, and to the Purkinje Fibers

Speed of conduction (fast or slow).

The amount of blood pumped or ejected by the left ventricle to the rest of the body in one minute.

The formula uses maximum and resting heart rate with the desired training intensity to get a target heart rate.

Cardiomyocytes are also known as heart muscle cells.

The increased volume of blood within the ventricle during the diastole phase of the cardiac cycle will cause an increase in the intensity of the stretches within the ventricular wall of the heart, causing the cardiac muscles of the ventricle to contract more forcefully!

The ability of the cardiac tissues to produce its own impulses
