What are the two loops of circulation in the body and what is their path?

The two loops of circulation in the body are the pulmonary circulation and the systemic circulation. In pulmonary circulation, deoxygenated blood is pumped from the right ventricle to the lungs via the pulmonary arteries, where it picks up oxygen and releases carbon dioxide before returning to the left atrium through the pulmonary veins. In systemic circulation, oxygenated blood is pumped from the left ventricle through the aorta to the rest of the body, delivering oxygen and nutrients to tissues and organs, and returning deoxygenated blood to the right atrium via the superior and inferior vena cavae.
