Where Does Systemic Circulation Begin

The heart pumps oxygenated blood out of the left ventricle and into the aorta to begin systemic circulation. After the blood has supplied cells throughout the body with oxygen and nutrients, it returns deoxygenated blood

What is the path of systemic circulation?

The systemic circulation refers to the path that carries blood from the left ventricle, through the body, back to the right atrium. In contrast, the pulmonary circuit refers to the path from the right ventricle, through the lungs, and back to the left atrium.

What is the first vessel of systemic circulation?

The first is the brachiocephalic artery, which shortly branches into the right subclavian artery (supplies the upper thorax, right arm and head) and right common carotid artery (supplies head).
