Trachycardia

100 and up heart rate

Bradycardia

60 and below heart rate

Normal Heart Rate

60-100 beats per minute

This receives the impulse from the SA node.

AV node

Blood enters the (blank) from the left ventricle to be distributed throughout the body.

Aorta

The (blank) valve prevents blood from flowing back into the left ventricle

Aortic

Which of the following valves prevents blood from flowing back into the left ventricle

Aortic

The (blank) has three cusps, is situated between the right atrium and the right ventricle and prevents blood from flowing back into the left ventricle

Aortic valve

The (blank) valve is also known as the mitral valve

Bicuspid

Which valve is between the left atrium and left ventricle?

Bicuspid

The (blank) has two cusps and is located between the left atrium and the left ventricle.

Bicuspid Valve

Which component of the conduction system is located between the ventricles?

Bundle of His

Inflammation of the heart is called

Carditis

The (blank) is thin and smooth and is the innermost layer of the heart

Endocardium

The function of the four valves of the heart includes

Ensuring one way blood flow

This layer of the heart is the outermost layer and contains fat to cushion the heart.

Epicardium

Blood returns to the heart from the king by the way of the pulmonary arteries

False

Pulmonary arteries carry oxygenated blood.

False

The aorta carries blood to the lungs

False

Veins carry blood away from the heart

False

Veins carry oxygen rich blood

False

When in the lungs, the blood absorbs both oxygen and carbon dioxide

False

The pulmonary veins empty the oxygenated blood into the (blank)

Left Atrium

When the (blank) contracts, blood is pushed through the aortic semilunar valve into the aorta.

Left ventricle

Which of these covers the thickest layer of the heart, which is made up of muscle?

Myocardium

Sac of the heart is (blank)

Pericardium

Which of these covers the heart and the large blood vessels attached to it?

Pericardium

Which of the following valves prevents blood from flowing back into the right ventricle

Pulmonary

When the right ventricle contracts deoxygenated blood is pushed through the pulmonary semilunar valve into a larger artery called the (blank)

Pulmonary Artery

When the right ventricle contracts, deoxygenated blood is pushed through the pulmonary semilunar valve into a larger artery called the (blank)

Pulmonary Trunk

The (blank) empty oxygenated blood into the left atrium.

Pulmonary Valve

The (blank) prevents blood from flowing back into the right ventricle. It is called a senilunar valve because its cusps are shaped like a half moon.

Pulmonary Valve

After the impulse flows through the flow through the (blank), the ventricles contract and the SA node starts the flow of a new impulse.

Purkinje Fibers

The (blank) is/are location in the lateral walls of the ventricles.

Purkinje Fibers

Blood that is low in oxygen and rich in carbon dioxide enters the (blank) of the heart

Right atrium

When the (blank) contracts, blood is pushed through the pulmonary semilunar valve into a larger artery called the pulmonary artery trunk

Right ventricle

The (blank) is/are located in the wall of the right atrium

SA node

The is known as the pacemaker of the heart

SA node

The (blank) separates the ventricles

Septum

The atria are separated from each other by a walled membrane known as the (blank)

Septum

The walled membrane so wearing the ventricle is the (blank)

Septum

Cardiac Electrolytes

Sodium Potassium Chloride Calcium

Damaged heart valves often allow blood to flow backwards.

True

In the body, blood brings oxygen to the cells and carries carbon dioxide away.

True

Pulmonary veins carry oxygenated blood

True

Veins of the body pick up the oxygen poor blood and empty it into the superior and inferior (blank)

Vena cava

Arteries carry blood away from the heart

true
