Q

The middle layer of the heart

A muscle layer that constitutes the largest percentage of the heart wall. Contractions of this muscle layer of force the blood from the heart into the vessels.

Requires a continuous supply of oxygen and nutrients, which are delivered through 2 coronary arteries that branch off the aorta above the aortic valve.

Q

The inner layer of the heart

This includes the heart valves that separate the chambers of the heart and provide a means of blocking the flow of blood from major vessels entering and exiting the heart.

A

Endocardium

17
Q

The top chambers of the heart which receives blood from the vein of the body

A

Atria

18
Q

The bottom chambers of the heart that pumps blood out to the body through arteries.

A

Ventricles

19
Q

Sets the rhythmic beating of the heart. It initiates these impulses at 60-100 times a minute.

A

Sinoatrial node (SA node)

Aka: pacemaker

20
Q

Located on the septal wall between the right atrium and the right ventricle

Holds impulse for a fraction of a second to prevent inappropriately high atrial rates and to permit the blood to empty from the atria through the tricuspid and mitral valve.

A

Atrioventricular node

21
Q

These completely encased both ventricles

A

Purkinje fibers

22
Q

The electrical impulse that causes the contraction of the atria and the ventricles

A

Depolarization
