fill in the blanks Blood that has circulated to the heart muscle itself also returns to the right atrium. Once blood leaves the cells of the myocardium, it flows into a system of cardiac veins, eventually flowing into the great cardiac vein, and then the coronary sinus. On this anterior view of the heart, locate the great cardiac vein and the coronary sinus (shown through to the back). Slide 14: Identify the two large veins that merge and flow into the superior vena cava: A._________________________________ and B._________________________________. (Note that unlike the arterial system, there are two veins, a right and a left, with this name.) Locate either the right or left brachiocephalic vein. Each is formed by the union of two slightly smaller veins. An C.___________________________ vein draining the head and a D.______________________ vein bringing blood back from the arm. Locate an additional vein draining blood from the head that flows into the subclavian vein, the E._____________________________ vein. Slide 15: Locate the external jugular vein, and observe the area that it drains. Which vein, internal or external jugular, is more superficial? A.___________________ Which vein, internal or external jugular, drains blood from the brain? B.___________________
