,Cardiac Blood Flow

• Liver to right atrium (RA) via inferior vena cava
• Superior vena cava drains venous blood from head and
upper extremities
• From RA blood travels through tricuspid valve to right
ventricle (RV)

,Cardiac Blood Flow

• From RV, venous blood flows through pulmonic valve to
pulmonary arteries
• Pulmonary arteries delivers unoxygenated blood to lungs
• Lungs oxygenate blood
• Pulmonary veins return oxygenated blood to left atrium
(LA)

, Cardiac Blood Flow

• From LA blood travels through mitral valve to LV
• LV ejects blood through aortic valve into aorta
• Aorta delivers oxygenated blood to body
