This system carries blood to the lungs for gas exchange and returns it to the heart

This is the name of the 2 superior chambers of the heart

This is the chamber that blood is pumped into after the right atrium

These discs are thick connections that join cardiocytes end to end

These valves account for the first heart sound "lubb"

This side of the heart supplies the blood to the pulmonary circuit?

This is known as the muscular wall between the two ventricles

This artery receives blood pumped from the left ventricle and then pumps blood to the rest of the body

The heart can be described as this because it does not depend on the nervous system for its rhythm

This type of rhythm is the normal heartbeat triggered by the SA node

This is the name of the thick partition that the heart lies between

Also known as the tricuspid valve, this valve has 3 cusps and helps to regulate blood flow from the right atrium to the right ventricle.

This artery takes deoxygenated blood from the heart to the lungs

This node is a patch of modified cardiocytes in the right atrium that begins the conduction system

After a slow inflow of sodium, what voltage-gated channels open when the pacemaker potential reaches its threshold

This is the name of the double-walled sac the heart is enclosed in

Also known as the left semilunar valve, this valve controls the opening from the left ventricle into the aorta

This is the name of the vein that brings blood back to the heart from the lower body

A type of a mechanical junction, these are patches of mechanical linkage that prevent the contracting cardiocytes from pulling apart

This wave is produced when a signal from the SA node spreads through the atria and depolarizes them

This is the space between the parietal and visceral membranes called?

These stingy tendinous cords help to connect the valves to the papillary muscles

Also known as the bicuspid valve and left AV valve, this valve regulates the flow of blood from the left atrium to the left ventricle

These are nerve like processes that arise from the lower end of the bundle branches and turn upward to spread throughout the ventricular myocardium.

This wave is generated by ventricular repolarization immediately before diastole
