The capillaries fulfill the function of "bridge" The capillaries lie between the veins and the arteries . Arteries carry oxygenated blood from the heart, while veins carry oxygen-depleted blood back to the heart. Veins and Arteries in Circulatory System: Vein and arteries play an inseparable role in circulatory system in which these two essential parts of our body carry the blood flow along with oxygen, essential nutrients, hormones, and other gases to the different body parts. The venules and veins returning blood to the heart. The veins of the stomach and intestines perform a unique function: instead of carrying blood directly back to the heart, they carry blood to the liver through the hepatic portal vein. It is a pumping organ that works in a rhythmic cyclic manner with a systole (shrinkage for .3sec) and diastole (expansion for .5 sec). The only exception are the pulmonary veins, which carry oxygenated blood from the lungs to the heart. All blood vessels have the same basic structure. This allows for modulation of vessel caliber and thus control of blood pressure. All arteries carry oxygenated blood-except for the pulmonary artery.The largest artery in the body is the aorta and it is divided into four parts: ascending aorta, aortic arch, thoracic aorta, and abdominal aorta.. After receiving blood directly from the left ventricle of the heart, the . Veins and arteries are major players in the circulatory system of all vertebrates. Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (generally veins carry deoxygenated blood to the heart however the pulmonary veins carry oxygenated blood also). An artery is an elastic blood vessel that transports blood away from the heart. These are two similar yet different types of blood vessels forming the parts of the circulatory system.
