How does the blood flow during systemic circulation?
From aorta to tissues of the body and back to the right auricle.
During systemic circulation, oxygenated blood from left ventricle is pumped to aorta. From aorta, blood is then pumped to various arteries which transport oxygen and nutrients to all tissues of the body. From there, veins carry deoxygenated blood and dump it in the right auricle of the heart.
