BIO310: Cardiovascular System Tutorial

What part of the intrinsic conduction system starts the heart beat?

• The atrioventricular node

• The Bundle of His

• The Perkinje fibers

• The sinoatrial node

The muscular layer of the heart that is responsible for pumping is the

• Endocardium

• Epicardium

• Myocardium

This chamber of the heart is much thicker than the others because it pumps to the entire body

• Right atrium

• Right ventricle

• Left atrium

• Left ventricle

Why is the mitral valve different from the other three valves of the heart?

• It only has 1 flap

• It only has 2 flaps

• It only has 3 flaps

The correct pathway that an erythrocyte would travel during systemic circulation is

• Arteriole--aorta--vein--venule--capillary

• Capillary--venule--vein--artery--aorta

• Aorta--arteriole--capillary--venule--vein

• Venule--vein--capillary--arteriole—aorta

The softer "dupp" sound of the heart is from

• The closing of the atrioventricular valve

• The closing of the semilunar valve

• The opening of the semilunar valve

You can check the pulse in your neck using the

• Brachial artery

• Jugular vein

• Carotid artery

• Popliteal vein

Which would be indicative of hypotension or low blood pressure?

• 120/80

• 170/120

• 80/65

All the veins of the systemic circulation drain into the:

• Superior vena cava

• Inferior vena cava

• Coronary sinus

• Superior and inferior vena cava

• Superior and inferior vena cava and coronary sinus

The left atrium receives blood from the:

• Systemic circulation

• Kidneys

• Liver

• Lungs
