The Human Body Is An Amazing Thing Essay

One of the most important systems in the body, keeping it alive, is the cardiovascular system. As a part of the circulatory system, the cardiovascular system pumps blood throughout the body through a network of many arteries and veins, providing it with nutrients and oxygen. Also, the cardiovascular fights infections and disease in the body and creates blood cells. Never the less, blood acts as a filtration system for the body and removes waste, cell debris, or bacteria from the bloodstream.

The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.

The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

The cardiovascular system consists of the heart, blood and blood vessels. The cardiovascular system is the major transport of materials to and from the cells. Blood is carried from the heart around the body via the arteries and the blood is then carried back to the heart via the veins. The

The cardiovascular system delivers blood, nutrients, ions, gases, and heat throughout your body. The cardiovascular system is a transportation system. It supplies oxygen to the body too and this is the most essential function of the cardiovascular system. http://www.livestrong.com/article/164894-5-major-functions-of-the-cardiovascular-system/ The cardiovascular system has other functions too. It carries digested food from the small intestine to all areas in the body that need it, distributes heat and fights diseases by using white blood cells to fight off

The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.

The circulatory system, also called the cardiovascular system, distributes vital nutrients throughout the body. The main organs are the heart and the blood vessels that run throughout the entire human body. Blood runs through the entire body, in the blood vessels, and contains cells and plasma.

There are three main functions of the cardiovascular system are: transportation where the heart pumps the blood vessels through the delivery way. It has been argued by (Medical terminology for cancer, 2014) that heart transports the respiratory gases, nutrients, wastes, and other substances that are needed by the body’s homeostasis to and from the cells by using the blood.

The cardiovascular system is composed of thousands of tubes, known as blood vessels that blood travels in. Blood is constantly being pumped to and from the heart through arteries and veins, respectively. Oxygen, nutrients, water, wastes are just some of the substances moving throughout the body via the blood vessels. Because this system is very complex, many issues can occur which inhibit the cardiovascular system from doing its job.

The heart is a muscular organ that pumps blood to continuously throughout your body. The heart is the center of the circulatory system. This system has blood vessels, such as arteries, veins, and capillaries. The blood vessels carry blood to and from all areas of the body. An electrical system regulates your heart and uses electrical signals to contact the walls of the heart. When the heart walls contract, blood pumps into the circulatory system. The heart chambers work to ensure that blood flows in the right direction. The heart is vital to your health and everything that goes on in your body. Without the pumping action, blood cannot circulate within the body. The blood carries oxygen and nutrients that your organs need to work properly. Blood

The system has two functions: to deliver oxygen and nutrients to cell and tissues & to remove carbon dioxide and other waste products from the cells and tissues. The base of the heart points toward the right shoulder, also it is about the size of your fist. The first layer of the heart wall is the epicardium. It is comprised of connective tissue that makes up the visceral pericardium. The middle layer is the myocardium, which is mostly cardiac muscle. The innermost layer is the endocardium. The heart has 4 chambers which allow is the pump correctly. Two atria chambers which receive blood and two ventricular chambers which discard of blood. There are two septa`s in the heart. The interventricular ( separates the 2 ventricles) and the interatrial (separates the 3 atria). Blood circulation is a thing because of the heart. Systemic circulation allows the blood to flow from the left side through the tissues and back to the heart entering on the right side. Pulmonary circulation allows the blood to flow from the right side to the lungs and back entering on the left side. A valve allows the blood to flow in one direction, it prevents backflow. There are 4 valves throughout the heart. They are the atrioventricular valve, bicuspid valve, semilunar valve, and the tricuspid valve. The two most important valves are the AV valve and the semilunar valve. The continuous circulation of blood through the body is vital for

The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.

The cardiovascular system is sometimes called the circulatory system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries. As the name implies, blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body.
