The cardiovascular system is divided into two circulations Pulmonary circulation blood to and from the lungs System circulation blood to and from the rest of the body Vessels carry the blood through the circuits Arteries carry blood away from the heart Veins carry blood to the heart Capillaries permit exchange

Thoracic Aorta

Blood Supply to the Heart Coronary circulation provides blood supply to the myocardium and pericardium of the heart. The Coronary Arteries Originate at the base of the ascending aorta from the corresponding aortic sinus. Superior to the aortic valve. Highest blood pressure of the systemic circuit

Left coronary artery (LCA) 15-20% Dominant Left coronary artery from the Aorta (Large) Located between the Pul. trunk. And the Lt. auricleIn the coronary groove. Divides Into Anterior descending artery (Lt. Ant. Descending or LAD). Supply the Rt and Lt Vent. 2/3 of the inter-vent. Septum (ant. Aspect by the Lt Diagonal Art). Circumflex artery gives SA node Branch Lt marginal Art. Ant & Post Ventricular Br. Atrial Br. Br. To the S-A Node (40%) supplies the left atrium, most of the left ventricle, part of the right ventricle, the IV septum (the anterior 2/3) and 40% of people the SA node possible to A-V node. Arterial anastomoses – interconnections between arteries (collateral Br.).

SA node Branch 40% Diagonal Brach Lt marginal from

Right coronary artery (RCA) 80-85% Dominant Art. Arises from the Aorta from the Rt Aortic sinus. Emerges between the Pul. Trunk and the Rt auricle Gives of Branches - Rt. Marginal Br. - 2-3 ventricular Br’s. (to the Ant surface Of the Rt - Ventr.). - 2 Posterior vent. Br. Supply The Diaph. Surface Of both Rt. And Lt. Ventr. - Artery to the SA nodal branch. - Artery to the A-V node (Septal Br). - Br.’s to the Rt. atrium supplies the RA, most of the RV, part of LV (diaphragmatic surface), Post 1/3 part of the IV septum, SA Br. (60% of pop.), and the AV node Br. (80% of pop.)

The Normal Heart - Coronary Artery Anatomy

Venous Drainage of the Heart Veins That Do open into the coronary sinus The coronary Sinus – Post. coronary sulcus Tributaries: Great and middle cardiac vein empties into the coronary sinus The Small cardiac vein. The Oblique vein of the Lt. atrium. Cardiac Veins The Posterior cardiac vein, middle cardiac vein, and small cardiac vein Some time empty into the great cardiac vain. Veins That Do not open into the coronary sinus Anterior cardiac veins (3-4in Number) empty into the Ant surface of the right atrium. The least cardiac veins (In all)
