Remember to follow along in your workbook to get the most out of this course!

Learning objectives

By the end of this module, you should be able to...

  • Identify the four chambers of the heart as well as the valves that connect them 
  • Follow the route the blood takes through the heart 
  • Identify and name the types of vessels that carry blood to and from the heart 
  • Identify the layers of the heart muscle tissue 
  • List the blood vessels that carry oxygen to the heart muscle itself and what parts of the heart they supply 

High Yield Content

  • Atrioventricular valves: tricuspid and bicuspid 
  • Bicuspid valve also called mitral valve
  • Semilunar valves: aortic and pulmonic 
  • Valves open when papillary muscles contract and pull on the chordae tendineae 
  • Arteries carry blood away from the heart and veins carry blood to the heart. (pulmonary artery carries deoxygenated blood and pulmonary veins carry oxygenated blood)
  • The diaphragm is the point where the descending thoracic aorta becomes the descending abdominal aorta 
  • Left coronary artery branches into LAD and circumflex
  • Right coronary artery branches into posterior descending and marginal arteries
