Wild Card
100

This vessel gives blood to the body

Aorta

100

The larger of the two ventricles

Left

100

This semi-lunar valve is the last stop before blood moves into the body

Aortic valve

100

The primary "pacemaker" of the heart

SA node

100

This valve is the first valve in the path of blood into the heart

tricuspid valve

200

This "vein" is misleading as it brings back oxygenated blood

Pulmonary vein

200

This chamber collects blood from the vena cava

right atrium

200

This semi-lunar valve closes the gates for de-oxygenated blood leaving the heart

Pulmonic valve

200

This node is the traffic light between signals from the top going to the bottom

AV node

300

This great vessel brings back blood from the "superior" head and neck

Superior vena cava

300

This chamber squishes blood through to the lungs

Right ventricle

300

The name given to the sound a heart valve makes when it doesn't close properly

Murmur

300

This conduction wave signals the depolarization of the atria

P wave

400

This large vein returns blood through the liver

Inferior vena cava

400

This chamber squishes blood through to the whole body

Left ventricle

400

The two heart sounds "lub dub"

s1 s2

400

the rate of conduction of signals for the primary pacemaker (hint; think of your vital signs)

60-100

500

The aortic arch and carotid sinus has these receptors to sense blood pressure changes

Baroreceptors

500

When talking about the degree of heart failure, we measure this chambers amount of power as a "fraction of ejection"

Left ventricle

500

The s1 heart sound represents the closure of these valves during systole

Mitral and Tricuspid

500

The rate of conduction through the purkinje fibres

20-40

500

Myocytes are autorhythmic, meaning they will contract on their own without a stimulus. What two cellular components make this possible?

Intercalated dics and gap junctions
