18. Under the microscope, I can see a section through one of the chambers of the heart. The myocardium is thick and the endocardium is very thin. In addition, I can see a valve that con this chamber to the next which has two cusps that prevent backflow from one chamber into another. Where in the heart am I? What does the thickness of the myocardium tell you about this region of the heart? What is the valve called? What does it do? What other valve would you see in this area of the heart? Where is it situated?
