Sistem peredaran darah terdiri atas jantung, pembuluh darah, dan saluran limfe. Jantung berfungsi sebagai pompa darah dan terletak di dalam rongga dada. Jantung dilapisi membran dan terdiri atas 4 ruang dan 4 katup yang mengatur aliran darah. Pembuluh darah mengalirkan darah dari dan ke jantung serta organ tubuh lainnya.

12. FIGURE 20-2 (c) The relationship between the heart and the pericardial cavity; compare with the fist and balloon example .

15. B. AN OVERVIEW OF THE CARDIOVASCULAR SYSTEM

17. Structural Differences between the Left and Right Ventricles

19. (c) Diagrammatic views of the ventricles just before a contraction (dilated) and just after a contraction (contracted).

25. Tricuspid Valve Katub Chordae Tendineae Muskulus Papillaris

27. (c) The aortic semilunar valve in the open (left) and closed (right) positions. The individual cusps brace one another in the closed position.

28. (a) When the ventricles are relaxed: The chordae tendineae are loose, and the papillary muscles are relaxed. the AV valves are open and the semilunar valves are closed.

29. (b) When the ventricles are contracting: the AV valves are closed and the semilunar valves are open. In the frontal section, notice the attachment of the left AV valve to the chordae tendineae and papillary muscles.

35. FIGURE 20-4 Layers of the Myocardium. Cardiac muscle tissue forms concentric layers that wrap around the atria and spiral within the walls of the ventricles.

36. Heart Wall

38. Major anatomical features on the anterior surface – 4 chambers

39. Major landmarks on the posterior surface. Coronary arteries (which supply the heart itself) are shown in red; coronary veins are shown in blue.

42. The Heart Valves

43. The papillary muscles and chordae tendineae supporting the right AV (tricuspid) valve.

45. A diagrammatic frontal section through the heart, showing major landmarks and the path of blood flow (marked by arrows) through the atria, ventricles, and associated vessels.
