Start your description with the left atrium using the following rubric: Rubric: Name the blood vessels that deliver blood to the left atrium and take blood away from the left side of the heart. Name the type of the blood in those vessels in respect to the oxygen levels (5 pts) Name the path that the blood follows after it is delivered to the left atrium (5 pts). What is the next chamber that receives blood? 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
