Explanation:
Detailed explanation-1: -In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta). The blood travels from the main artery to larger and smaller arteries and into the capillary network.
Detailed explanation-2: -The blood moves from the aorta through the systemic arteries, then to arterioles and capillary beds that supply body tissues. Here, oxygen and nutrients are released and carbon dioxide and other waste substances are absorbed. Deoxygenated blood then moves from the capillary beds through venules into the systemic veins.
Detailed explanation-3: -The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.
