The Circulatory System By Kyle Pickett, Dan Koerner, Raymond Wood, Kate Collins, and Gia DeGregory Parts of the circulatory system Major Functions The heart: The heart is like a pump. It pumps blood all around the body. The Artery: The Artery carries the blood to the heart. The Vein: Veins carry blood to all of the muscles and organs throughout the body. The Capillaries: let only a few blood cells through at a time. Components Red Blood Cells: The transport oxygen through the body. White Blood Cells: They help the body fight against bacteria and diseases. Plasma: They help transport red and white blood cells. Blood Path The arteries carry blood to the heart and veins carry blood away from the heart. The blood path is like a web that goes through the major organs and muscles. They travel through the arms, legs, head, toes, and fingers. Systems that work together (Digestive) The Digestive System: It breaks down food so that it can be absorbed into the circulatory system. Then the circulatory system carries the nutrients to the tissues to use and remove wasts. Systems that work together (Muscular) Without the muscular system the heart would not function. The circulatory system provides food as glucose and oxygen so muscles can do their work. Systems that work together (Respiratory) You breathe in oxygen into your lungs. The oxygen diffuses across the thin wall of the Alveoli in the lungs and the thin walls of the blood vassals. The posses repeats itself over and over again. Five facts about the circulatory system The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart, arteries, capillaries and veins. The average adult heart can beat up to 70 times per minute. If there are 1,440 minutes in a day there would be… 100,800 times per day! When the heart pumps blood, it travels through blood vessels all over the body. Because blood needs to reach all the different corners of the body, the average person has so many blood vessels that their length could circle twice around the world! A person has about six quarts of blood that these amazing blood vessels help to circulate! Continuing Five facts about the circulatory system A vein is an elastic blood vessel that transports blood from various regions of the body to the heart. Veins can be grouped into four main types: pulmonary, systemic, superficial, and deep veins.
