BIO 139 Cardiovascular Study Guide

The first heart sound is caused by the:

• closing of the atrioventricular valves

• opening of the atrioventricular valves

• closure of the semilunar valves

• movement of blood into the ventricles

The upper chambers of the heart are called:

• Atria

• Ventricles

• Arteries

• Veins

The left ventricles pumps blood into:

• The Pulmonary Circuit

• The Systemic Circuit

Right-sided heart failure results from the right side of the heart not working well. Predict one of the effects of right-sided heart failure.

• Blood will not be adequately oxygenated

• Not enough blood will be delivered to body tissues

• There will be backup of blood in the pulmonary circuit

• Less blood from the body will be returning to the heart

What surface groove separates the right and left

ventricles?

• interatrial septum

• interventricular sulcus

• interventricular septum

• atrioventricular sulcus

Which of the following valves would be affected if papillary muscles and/or chordae tendinae stopped functioning?

• Pulmonary valve

• Mitral valve

• Aortic valve

• None of the answers are correct.

  
  

How might coronary artery anastomoses help a patient with a coronary artery disease?

• Anastomoses provide an alternate route of blood flow around a coronary artery that may be blocked.

• Anastomoses prevent stenosis from occurring.

• Anastomoses can increase the frequency of action potential propagation within the myocardium.

• Anastomoses increase sinoatrial node activity if heart failure were to occur.

The cusps of the atrioventricular valves attach to the papillary muscles via the...

• chordae tendineae

• intercalated discs

• trabeculae carneae

• Purkinje fibers

What is the most superficial layer of the pericardial sac?

• parietal pericardium

• epicardium

• visceral pericardium

• fibrous pericardium

Which of the following vessels carries oxygenated

blood?

• pulmonary artery

• pulmonary trunk

• pulmonary vein

• superior vena cava
