Study Guide: The Heart

1

The visceral pericardium is found

1

The correct layers of the heart, from superficial to deep, are

1

The atrioventricular valves are also called

1

Semilunar valves prevent backflow of blood into the

1

The most abundant blood supply goes to the

1

Branching of an artery as it progresses from proximal to distal is called

1

Which of the following is a semilunar valve

1

Rhythmic compressions of the heart combined with effective artificial respiration in cases of cardiac arrest are knows as .

1

Increased serum levels in the blood often indicate a recent myocardial infraction. These levels are often monitored by a blood test called and a blood marker known as .

1

Because cardiac muscles are capable of contracting on their own in a slow, steady rhythm, they are considered .

1

The free edges of the cuspid flaps are anchored to the papillary muscles of the ventricles by several tendinous cords that are more commonly referred to as .

1

A tiny bump at the end of a T wave is usually

1

The normal pattern of impulse conduction through the heart is

1

An ECG P wave represents

1

Repolarization of the atria is

1

Contraction of the ventricles produces

1

The contraction phase of the cardiac cycle is referred to as systole.

1

Vagus fibers to the heart serve as accelerator nerves.

1

The QRS complex represents repolarization of the ventricles

1

Rapid ejection is characterized by a marked increase in ventricular and aortic pressure and in aortic blood flow.

1

Isovolumetric ventricular contraction occurs between the start of ventricular systole and the opening of the semilunar valves.

1

are also known as Purkinje fibers.

1

Pacemakers other than the SA node are abnormal and are usually .

1

A complete heartbeat is referred to as a .

1

A considerable quantity of blood called the , normally remains in the ventricles at the end of the ejection period.

1

A swishing abonormal heart sound indicating an incomplete closing of the valves or a stenosis of them is known as a .

1

A valve that permits blood to flow from the right ventricle into the pulmonary artery is called the

1

The left chambers are separated form the right chambers by an extension of the heart wall called the .

1

return blood from various tissues to the heart.

1

Myocardial cells receive blood by way of two small vessels, the right and left .

1

The death of ischemic heart muscle that is usually the result of blood clot to one of the larger coronary artery branches is knows as .

1

The cardiac veins drain into the right atrium through a common venous channel called the .

1

The P Wave represents ( depolarization, repolarization ) of the atria.

1

The QRS complex represents ( depolarization, repolarization ) of the ventricles.

1

At the same time that the ventricles are depolarizing, the atria are ( repolarizing, depolarizing ).

1

The T wave reflects ( depolarization, repolarization ) of the ventricles.

1

An inverted T wave is often seen following a ( myocardial infaction, pericarditis ).

1

Ventricular diastole begins with the isovolumetric ventricular relaxation period of the cardiac cycle.

1

A stenosed valve is narrower than normal.

1

Trace the blood flow through the heart by numbering the following structures in the corner sequence. Start with number 1 for the right atrium and proceed until you have numbered all the structures

❌ right atrioventricular (tricuspid) valve
❌ pulmonary veins
❌ pulmonary arteries
❌ pulmonary semilunar valve
❌ left atrioventricular (mitral) valve
❌ left ventricle
❌ right atrium
❌ right ventricle
❌ left atrium
❌ aorta
❌ aortic semilunar valve
