NURSING 384 - Week 5 Review.

NURSING 384 - Week 5 Review/NURSING 384 - Week 5 Review. 1. Explain the flow of blood through the heart.  Right side (unoxygenated): o SVC and IVC to right atrium to tricuspid valve to right ventricle to pulmonic valve to pulmonary artery to lungs  Left side (oxygenated): o Pulmonary veins to left atrium to mitral valve to left ventricle to aortic valve to systemic circulation  1, The right atrium receives venous blood from the inferior and superior venae cava and the coronary sinus. The blood then passes through the tricuspid valve into the right ventricle. 2, With each contraction, the right ventricle pumps blood through the pulmonic valve into the pulmonary artery and to the lungs. 3, Oxygenated blood flows from the lungs to the left atrium by way of the pulmonary veins. 4, It then passes through the mitral valve and into the left ventricle. 5, As the heart contracts, blood is ejected through the aortic valve into the aorta and thus enters the systemic circulation
