1) Determine left from right by looking at the thickness of the myocardium - Left ventricle pumps against more resistance therefore it needs more muscle power! 2) Determine the valves by looking at their location - Are they entering the ventricle? Yes then they are AV valves. Knowing the left from the right will help determine how many flaps the valve has there are - Are they exiting the ventricles? Yes - knowing left from right will determine the which semilunar valve it is. The Academic Support Center @ Daytona State College (Science 58 Page 2 of 27)

Figuring out Blood Vessel Anatomy 1) Identify Surrounding Organs - This helps determine what blood the vessel is carrying. 2) What color is the blood vessel - This will determine the direction of blood flow - Red: arteries carry blood away from the heart - Blue: veins carry blood to the heart - Yellow: hepatic portal system carrying blood to the liver to be detoxified The Academic Support Center @ Daytona State College (Science 58 Page 17 of 27)

Notice the heart Notice the aorta Notice the brachiocephalic vein The Academic Support Center @ Daytona State College (Science 58 Page 20 of 27)
Notice the thick vein exiting the blue lump structure (the kidney) The Academic Support Center @ Daytona State College (Science 58 Page 21 of 27)
Notice the intestines Notice the long abdominal aorta Notice the thick veins exiting the blue lump structure (the kidney) Notice artery going toward the intestines The Academic Support Center @ Daytona State College (Science 58 Page 22 of 27)
Notice the tube with the cartilage rings Notice the left and right subclavian veins Notice the aorta below the subclavian veins The Academic Support Center @ Daytona State College (Science 58 Page 23 of 27)
Notice the lungs Notice the lump in the middle (the heart) Notice the arteries coming out the of the heart Notice the superior vena cavae The Academic Support Center @ Daytona State College (Science 58 Page 24 of 27)
Notice the blue lump (the kidney) Notice the common iliac Notice were the artery exits the abdominal aorta The Academic Support Center @ Daytona State College (Science 58 Page 25 of 27)
