in class Heart Anatomy and Function Quiz

What are the four chambers of the heart?

• Right Atrium, Right Ventricle, Left Atrium, Left Ventricle

• Right Atrium, Left Atrium, Right Ventricle, Left Ventricle

• Right Ventricle, Left Ventricle, Right Atrium, Left Atrium

• Left Atrium, Right Atrium, Left Ventricle, Right Ventricle

Name the layers of the heart wall.

• Epicardium, Myocardium, Endocardium

• Pericardium, Myocardium, Endocardium

• Epicardium, Pericardium, Endocardium

• Pericardium, Epicardium, Myocardium

The function of the myocardium is to:

• Pump blood throughout the body

• Filter waste from the blood

• Transmit nerve impulses

• Store energy in the form of fat

The function of the tricuspid valve is to:

• Prevent backflow of blood into the right atrium

• Pump blood into the left ventricle

• Regulate blood flow to the lungs

• Control the heart rate

Which vessels carry oxygenated blood to the heart?

• Pulmonary veins

• Pulmonary arteries

• Superior vena cava

• Inferior vena cava

The role of the pulmonary valve is to:

• Regulate blood flow from the right ventricle to the pulmonary arteries

• Prevent backflow of blood into the left atrium

• Control the flow of oxygenated blood to the body

• Maintain the pressure in the left ventricle

What does the P wave represent in an ECG?

• Atrial depolarization

• Ventricular depolarization

• Atrial repolarization

• Ventricular repolarization

Describe the significance of the QRS complex.

• It represents the depolarization of the atria.

• It represents the depolarization of the ventricles.

• It represents the repolarization of the ventricles.

• It represents the repolarization of the atria.

What does the T wave indicate in an ECG reading?

• Atrial depolarization

• Ventricular depolarization

• Ventricular repolarization

• Atrial repolarization

How can you identify atrial fibrillation on an ECG?

• Irregularly irregular rhythm

• Regular rhythm

• Prolonged PR interval

• ST segment elevation
