How the body travels through your body is the pattern of blood flow through the body is similar to a figure eight. The heart is at the center where the two loops cross. Blood travels through the first loop and travels from the heart to the lungs, then back to the heart. in the second loop, bold travels through every part of your body and back to the heart. There are three types of blood vessels called arteries, capillaries, and veins. Arteries carry blood away from the heart. The largest artery in the body is the aorta. From the arteries, blood flows into tiny vessels called capillaries. From capillaries, blood flows into veins that carry blood back to the heart.

There are eight parts to the circulatory system, they are the heart, atrium, ventricle, valve, artery, aorta, capillary, and the vein. The circulatory system is a organ system that transports needed materials to cells and removes waste from cells. What the heart is a hollow, muscular organ that pumps blood throughout an organism's body. The atrium is an upper chamber of the heart that receives blood. A ventricle is a lower chamber of the heart that pumps blood out to the lungs and the body. Next, is the valve which is a flap of tissues in the heart that prevents blood from flowing backwards. A blood vessel that carries blood away from the heart is called an artery. The aorta is the largest artery in the body; receives blood from the left ventricle. The capillary is a tiny vessel where substances are exchanged between blood and body cells. Lastly, the blood vessel that carries blood back to the heart is called a vein.
