Body Systems

Think About It!
Have you ever really thought about how your body works? How you eat? Or even how you move? Your body has different systems that work together to keep your body healthy. Here are the systems and how they work:
The Circulatory System
The Circulatory System contains 4 parts: The heart, blood, arteries, capillaries, and the veins. Each of these parts have an important role. The heart is divided into two parts and each part works as a separate pump and sends blood along to separate paths. The arteries are blood vessels that carry blood away from you heart to other parts of the body. The veins are also blood vessels that take blood from cells back to the heart.
The Digestive System
The The Digestive System includes 8 parts: The teeth, tongue, epiglottis, esophagus, stomach, small intestine, large intestine, and the colon. These parts all work together to make the system run smoothly. The teeth and tongue help crush up the food that you eat so it is easier to swallow. The epiglottis is a flap that covers certain passage ways so that you food or drink does not go down the wrong pipe. Your esophagus is a pipe that carries food down to the stomach. Your large intestine and colon take water out of the wast. And Finally, your small intestine absorbs nutrient and puts it in the blood.
The Respritory System
The Respiratory system has 7 parts: The lungs, the sinus cavity, trachea, bronchial tubes, bronchioles, air sacs, and diaphragm. The allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. The sinus cavity warm and moisten the air. The trachea is a tube that carries air in from the larynx to the lungs. The bronchioles are tubes that connect to the bronchi and branch into smaller and smaller tubes. Air sacs are whre oxygen enters the blood and carbon dioxide leaves the blood.
Systems Working Together
What system do you think is the most important? Well, all of your systems work together, and when one of these systems go wrong, it effects all of them. For example, respiratory system and the circulatory system work together to get oxygen to your cells. The respiratory system gets the oxygen as far as the tiny air sacs in your lungs. The blood picks up the oxygen there and carries it to all of your cells--all the way to your toes.
