Coronary Blood Supply
Blood circulation to the heart muscle made up of:
Right Coronary Artery
Left Coronary Artery, which branches to:
- Circumflex: wraps around
- Left Anterior Descending (LAD)
Pulmonary Circuit
- ) From RV, deoxygenated blood carried by Pulmonary Artery to lungs
- ) Blood picks up oxygen, drops of carbon dioxide
- ) Oxygen rich blood carried by 4 Pulmonary Veins to LA
Pulse
Created by muscular contraction of LV
Systemic Circulation
- ) Aorta leaves LV, takes oxygenated blood to cells of body
- ) Arteries, carry away from heart to arterioles
- ) Arterioles to Capillaries
- ) Capillary exchange O2/CO2, transfer to Venules
- ) Venules to Veins then back to heart
Carotid Artery
Supplies blood to the head, neck, and brain
Femoral Artery
Supplies blood to the thigh and legs
Renal Artery
Supplies blood to the kidneys
Pericardium

Conduction System (Electrical flow of heart)
- ) SA-Node
- ) Atrial Chambers
- ) AV Node
- ) Bundle of HIS
- ) Right/Left Purkinje Fibers
- ) Ventricle Chambers
Layers of Heart
Epicardium (Pericardium) - outermost layer
