1 Arteries are elastic vessels that transport blood away from the heart. 2  Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells. 3  Systemic arteries deliver blood to the rest of the body. 4  Veins. 5  Veins are elastic vessels that transport blood to the heart. Blood is circulated through the body via the cardiovascular system. This system is comprised of the heart and the circulatory system. Blood vessels carry blood from the heart to all areas of the body. The blood travels from the heart via arteries to smaller arterioles, then to capillaries or sinusoids, then to venules, to veins, and back to the heart. Microcirculation deals with the flow of blood from arterioles to capillaries or sinusoids to venules Capillaries, which are the smallest and most numerous blood vessels in the human body (ranging from 5 to 10 micrometers in diameter and numbering around 10 billion) are also the thinnest walled vessels; an inner diameter of 5 um is just wide enough for an erythrocyte to squeeze through. Blood flows throughout the body tissues in blood vessels, via bulk flow (i.e., all constituents together and in one direction). Arteries. The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. 1  Arteries begin with the aorta, the large artery leaving the heart. 2  They carry oxygen-rich blood away from the heart to all of the body's tissues. 3  They branch several times, becoming smaller and smaller as they carry blood further from the heart. Capillaries. 1  Capillaries are small, thin blood vessels that connect the arteries and the veins. 2  Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells. The blood vessels-arteries, capillaries, and veins-are an extensive network of elastic tubes that carry blood to and from the heart and throughout the body. The blood vessels are the transportation system of the human body.  The blood moves around the body in the circulatory system. This is made up of blood vessels (tubes) called arteries, veins and capillaries. The blood keeps moving through these blood vessels because it is pumped by the heart. Arteries carry blood that is full of oxygen from the heart to all parts of the body. As the arteries get further and further away from the heart, they get smaller and smaller. Eventually they turn into capillaries. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body. The lymphatic system primarily consists of lymphatic vessels, which are similar to the circulatory system's veins and capillaries.
