Beginning in the right atrium of the heart, explain the major anatomical structures that a drop of blood passes through before ending up in the aorta. Make sure to include valves, vessels, and heart chambers in your answer.

Fill in the blanks for the following statement related to the major veins that empty into theright atrium of the heart. threemajor______________, the _____________and inferior _____________ ______________ andthe ______________ sinus. The ______________ _____________ ________________ returns all the _________________ tothe heart from tissues superior to the heart in the head, neck, arms and upper thorax.

B.The ascending aorta is approximately 2.6 cm in diameter. The aortic arch is approximately 5 cm above the heart. What is the pressure in the aorta at the beginning of the aortic arch during discharge? (You can assume the blood is experiencing hichehnningles) Clearly state any assumptions.

C. One of the semilunar valves separates the left ventricle from the aorta. If the pressure in the left ventricle is 91.3 mmH (12,173 Pascal) during the start of aortic discharge, what is the friction coefficient (Knitting) for the semilunar valve? Clearly state any assumptions.
