Which type of circulation carries freshly oxygenated blood from the heart to the rest of the body?

Systemic circulation is responsible for transporting freshly oxygenated blood from the heart to all parts of the body, delivering vital oxygen and nutrients to tissues and organs. This process begins when oxygen-rich blood leaves the left ventricle of the heart through the aorta, branching off into smaller arteries that reach different body areas. After the oxygen is delivered and carbon dioxide is collected from the tissues, the now deoxygenated blood returns to the heart through veins, entering the right atrium.

In contrast, pulmonary circulation focuses on transporting deoxygenated blood from the heart to the lungs for oxygenation and then returning the oxygen-rich blood back to the left side of the heart. Coronary circulation pertains specifically to the supply of blood to the heart muscle itself. Portal circulation involves the delivery of blood from one organ to another, notably from the digestive tract to the liver. Each type of circulation serves a unique and critical function in maintaining the overall health and efficiency of the body, but systemic circulation is specifically tasked with oxygen delivery to tissues.
