Its function is to distribute blood and other nutrients to all your body’s organs and tissues. The structure of your heart. This system has three main functions: Protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. The heart, blood and blood vessels work together to service the cells of the body. As mentioned several times, the circulatory system has several functions in addition to transporting nutrients. This system causes heart muscle depolarization in only one direction- from the atria to the ventricles; it enforces a contraction rate of approximately 75 beats per minute on the heart, thus the heart beats as a coordinated unit. Your heart works as a pump that pushes blood to the organs, tissues, and cells of your body. The cardiovascular system consists of the heart, blood vessels, and blood. The cardiovascular system is one of the most amazing organ systems in your body. The systemic circulation can also be seen to function in two parts – a macrocirculation and a microcirculation. Blood cells are made up of three parts, and each part has a job to do when it comes to protecting your body from infection or illness. Contents Functions of the cardiovascular system Blood Blood vessels The heart The spleen Roots, suffixes, and prefixes Cancer Focus Related Abbreviations and Acronyms Further Resources Functions of the cardiovascular system. To protect the body from infection and blood loss 3. The cardiovascular system circulates oxygen and nutrients throughout the body. Your circulator system is a complex network of different organs and vessels that ensure proper flow of nutrients, blood, hormones and oxygen to and from cells. It is always working hard while it circulates blood throughout … The cardiovascular system or circulatory system is a system which moves nutrients, gases and wastes between cells, helps fight diseases, and transports blood throughout the body (Circulatory System). All the veins drain into the superior and inferior vena cava which then drain into … system and the heart. The removal of waste and toxins is a function performed by the lymphatic system. There are several different circuits contained in the cardiovascular system. from your Reading List will also remove any The heart is where circulation and cooperation between the respiratory and the cardiovascular systems begin. To help maintain fluid balance within the body The arterial circulation delivers blood from the heart to the body, and the venous circulation carries it … PIXOLOGICSTUDIO/Science Photo Library/Getty Images Heart . Your heart is a pump. All rights reserved. Pump: HEART Network of Tubes: BLOOD VESSELS CONTENT 6. o It is a transportation system which uses the blood as the transport vehicle. Are you sure you want to remove #bookConfirmation# Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. The circulatory system performs a number of vital functions in the body. The arterial circulation delivers blood from the heart to the body, and the venous circulation carries it back to the heart. The circulatory system and the respiratory system work closely together to ensure that organ tissues receive enough oxygen. Here's how it all breaks down: In order to stay healthy and work at the optimum level, your body must keep a nearly constant temperature. The right ventricle and atrium are where blood is received from the veins. extensive network of organs and structures that allow the blood to circulate throughout the body 4. Blood is a living fluid. It also carries away waste products and carbon dioxide, helps to regulate body temperature, and helps to maintain normal water and electrolyte balance. Oxygenated and nutrient rich blood is distributed to tissues via the arterial system, which branches into smaller and smaller blood vessels from arteries to arterioles to capillaries (where most exchange occurs). To compensate, your body then triggers hormones that target certain functions, such as increasing urine output or kidney function. The cardiovascular system consists of the heart, blood vessels, and blood. It provides all the living cells of the organism with the materials required for their normal functions (e.g., O2 and nutrients) ... by way of the interstitial (extracellular) fluid. The primary function of the heart and blood vessels is to transport oxygen, nutrients, and byproducts of metabolism. Your heart is made up of three layers of tissue: Pericardium – a thin outer lining that protects and surrounds your heart. In simple terms, the primary function of the cardiovascular system is to carry substances vital to life to cells and tissues and to transport waste products from cells and tissues to sites of elimination from the body. The main function of the cardiovascular system is to transport nutrients, waste products and gases around the body. The blood als… The cardiovascular system is crucial in many other ways, not just in moving oxygen and blood around. Digested nutrients are absorbed into the bloodstream through capillaries in the villi that line the small intestine. Functions of the Cardiovascular System: The functions that are performed by this organ system can be categorized into three main domains: transport, regulation and protection. The circulatory system, also known as the cardiovascular system, consists of the organs and fluids that transport materials like oxygen and nutrients throughout the body. Your circulatory system is vital to your survival. Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s hardest-working organ — the heart, which is only about the size of a closed fist. Circulatory system. Though the optimum temperature can vary from one person to another, for most it lies between 97 and 99 degrees Fahrenheit.
