Describe the sequence of the contractility of the respective cardiac chambers so that the blood can be propelled out of the heart toward the tissues ( 5 pts), Name all the valves that the blood has to go through in order to enter and exit from the left ventricle  (5 points), Where is the site of gas exchange for the systemic circulation? (2 pts) How is the blood returned to the heart? Name the vessels and the cardiac chamber. (3 pts)   Points will be subtracted for incomplete/vague, missing, or wrong answers as follows: 25, 50 or 75 % point reduction for incomplete/vague answers (depending on the quality of the answer). 0 pts for missing or wrong answers
