Pericardium - (answer)Outer protective double-layered sac surrounding the heart.
Epicardium - (answer)Thin outermost layer of the heart, contains coronary arteries.
Myocardium - (answer)Middle muscular layer of the heart, contains electrical system.
Endocardium - (answer)Inner most layer of the heart, lines chambers and valves.
Blood flow through the heart - (answer)Venules --> Veins --> Superior/Inferior VC --> Rt atria -->
Tricuspid Valve --> Rt ventricle --> Pulmonary valve --> Pulmonary Artery --> Lungs --> Pulmonary Veins --
> Lt atria --> Bicuspid/Mitral valve --> Lt ventricle --> Aortic Valve --> Aorta --> Arteries --> Arterioles -->
Capillaries --> Body
Deoxygenated blood(left side of heart) - (answer)Venules --> Veins --> Superior/Inferior VC --> Rt atria --
> Tricuspid Valve --> Rt ventricle --> Pulmonary valve --> Pulmonary Artery
Oxygenated blood(right side of heart) - (answer)Pulmonary Veins --> Lt atria --> Bicuspid/Mitral valve -->
Lt ventricle --> Aortic Valve --> Aorta --> Arteries --> Arterioles --> Capillaries
Atrioventricular Valves(diastole) - (answer)Valves between the atria and ventricles. Tricuspid,
Bicuspid/Mitral. Regulates blood flow IN the heart.
Semilunar Valves(systole) - (answer)Pulmonary and Aortic valves separates Ventricles from
corresponding artery. Regulates blood flow OUT of the heart.
sinoatrial node (SA node) - (answer)Primary pacemaker, 60-100bpm intrinsic rate
