Across
  1. 5. situated in the middle mediastinum and Restricts excessive movements of heart.
  2. 6. A semilunar valve consisting of three crescent-shaped cusps. It does not have chordae tendineae or papillary muscles.
  3. 8. transports oxygen-poor blood to the right atrium
  4. 10. is a projection on the anterior aspect of the left atrium
  5. 14. composed of two leaflets (anterior and posterior, supported by chordae tendineae attached to the papillary muscles of the left ventricle
  6. 16. lines the inside of the heart chambers and covers the heart valves and Provides a smooth surface to reduce resistance to blood flow within the heart
  7. 17. Located between the right atrium and right ventricle.
Down
  1. 1. Communicates with the right ventricle through right AV orifice (tricuspid orifice)
  2. 2. Forms the left surface, apex, part of the left border, part of the anterior surface, part of the inferior border and most of the diaphragmatic surface of the heart.
  3. 3. A semilunar valve with three cusps (leaflets), similar in structure to the pulmonary valve, but slightly thicker to withstand higher pressure
  4. 4. visceral layer of the pericardium that contains fat and blood vessels that supply the heart
  5. 7. the Left atrium communicates with left ventricle through this left orifice
  6. 9. ensures one-way blood flow from the left atrium into the left ventricle during diastole
  7. 11. the heart is located in the middle of this space, within the pericardium
  8. 12. contracts to propel blood out of the heart chambers and into the circulatory system and is most prominent in the left ventricle
  9. 13. outer layer of serous pericardium, lines the inner surface of fibrous pericardium.
  10. 15. Presents a shallow, oval shaped depression – fossa ovalis
