Document Summary

Know names of all these vessels and how they work. Second picture is looking at heart from side, anterior interventricular artery (big) and form anastomosis/curciut with posterior robust network of vessels. Lack of blood supply (escemia) co(cid:374)ducti(cid:374)g syste(cid:373) does(cid:374)"t get e(cid:374)ough. Origins of coronary arteries are within pockets of right and left semilunar valves. For most arteries theres coronary veins that run with it. Most stuff going on at back draining into coronary sinus. Between two ventricles is great cardiac vein becomes enlarged as coronary sinus which drains into right atrium. Also theres small cardiac vein drains right ventricle, travels around heart and drains into sinus. Except anterior cardiac veins poorly defined, variable they drain directly into right atrium vs the sinus. Middle cardiac vein side by side w posterior interventricular artery. All of the veins drain into coronary sinus except anterior cardiac veins. Anterior interventricular sulcus we would find great cardiac vein sulcus.
