Discription The posterior (or back) aspect of the circulatory system is a network of major blood vessels that supply blood to the lower body and back. These vessels branch off from the aorta and pulmonary arteries, delivering oxygenated blood to the muscles, organs, and tissues in the posterior regions, including the legs, feet, and back. This system also returns deoxygenated blood from these areas back to the heart through a network of veins. A properly functioning posterior circulatory system is vital for maintaining the health, vitality, and functional capacity of the lower body by ensuring these regions receive necessary oxygen and nutrients and effectively removing metabolic waste.
