Sheep Heart

Sheep Heart. Left Auricle. Anterior longitudinal sulcus. You can find the anterior side of the heart by finding the auricle that you can see completely; it is the left auricle. The anterior longitudinal sulcus is on that side and the coronary sinus is on the posterior side.

Presentation Transcript

  1. Sheep Heart

  2. Left Auricle Anterior longitudinal sulcus You can find the anterior side of the heart by finding the auricle that you can see completely; it is the left auricle. The anterior longitudinal sulcus is on that side and the coronary sinus is on the posterior side.

  3. What LAYER of tissue is this? Endocardium (inside all chambers where blood touches) Myocardium (meaty areas of brown muscle Visceral pericardium (outer shiny surface of heart) Apex

  4. What CHAMBER is this? Right atrium What CHAMBER is this? Left atrium What CHAMBER is this? Right ventricle What CHAMBER is this? Left ventricle Apex

  5. Atrial septum Right atrium Left atrium Tricuspid valve Mitral (bicuspid) valve Left ventricle Right ventricle Apex Apex Interventricular septum

  6. Aortic semilunar valve Mitral (bicuspid) valve Cordaetendonae Papillary muscles Trabeculaecarnae

  7. Aortic semilunar valve Mitral (bicuspid) valve Cordaetendonae Papillary muscle Trabeculaecarnae

  8. Mitral (bicuspid) valve

  9. Mitral (bicuspid) valve Papillary muscle

  10. Tricuspid valve

  11. Atrial septum Right atrium Left atrium Tricuspid valve Mitral (bicuspid) valve Left ventricle Right ventricle Apex Apex Interventricular septum

  12. Pulmonary trunk Aorta Superior vena cava

  13. Aorta Pulmonary trunk, which branches into pulmonary arteries Pulmonary veins enter Left atrium Aortic semilunar valve

  14. Aorta

  15. Superior vena cava Inferior vena cava Pulmonary vein

  16. Pulmonary artery (leaving right ventricle)

  17. Pulmonary artery as seen from back of heart (leaving right ventricle) Coronary sinus (back of heart)

  18. Moderator band (right ventricle only)

  19. Moderator band

  20. Inferior View of the Heart Figure 18.5d

  21. Posterior view of heart Trachea Superior vena cavae Aorta Pulmonary veins Pulmonary veins Left Atrium Right Atrium Coronary sinus Inferior vena cavae Posterior interventricular artery

  22. Coronary Sinus (back vein of heart)

  23. Coronary Sinus (back vein of heart)

  24. Pectinate Muscles are parallel ridges in the walls of the atria of the heart. They resemble the teeth of the comb.

  25. Ascending Aorta

  26. Marginal arteries

  27. Pulmonary semilunar valve Mitral (bicuspid) valve Aortic semilunar valve (look deep under here) Tricuspid valve Cordae tendonae Papillary muscles Trabeculae carnae
