The Heart: The Cardiovascular System

The cardiovascular system consist of the heart, also known as the circulatory system. The major organs in this system is the heart, blood,capillaries, veins and arteries. When I hear cardiovascular system I automatically think about life itself. We have to have the heart in order to survive. The heart is the major organ in the cardiovascular system, it pumps blood throughout the body to organs, tissue, and cells. Think of the heart as being the fuel pump on the car. The fuel pump has to pump the gas to the engine to keep that car running. Same thing with the heart the heart has to pump blood to our bodies in order for us to run. Then you have the blood it's job is to carry oxygen and nutrients to every cell in the body and to remove any waste

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.

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 heart is located between lungs and it is protected by the rib cage, it is thought to be the same size as a closed fist. The heart is protected a membrane called pericardium, this membrane contains a film of fluid which helps prevent fiction. Each side of the heart consist of an atrium and a ventricle. The right side of the

Oxygen and nutrients the body requires for function are pumped around this complex network of blood vessels by the heart. At roughly the size of a human fist, the heart is a four-chambered muscle and performs two functions of circulation simultaneously and continuously. Systemic and pulmonary circulation. The heart is made up from three separate layers of cardiac tissue; the outer layer called the pericardium, which is a double sac-like outer covering with serous fluid inside to keep the middle layer, the myocardium from adhering to the outer layer. This middle layer of the heart is the heart muscle which is thicker on the left side, to aid with the pressure needed to sustain systemic circulation. The inner layer of the heart is the endocardium. It’s lining is smooth to help prevent the blood which circulates around the inside of the heart from clotting. The heart is the human body’s in-built pacemaker, and the electrical signals sent through the it cause the heart to contract and relax. This process is triggered by the autonomic nervous system and the contraction and relaxing cycle is

The system works because in blood there are antigens and agglutinogens. In type A, only type A antigens on the red blood cells. Similar to this type B only has type B antigens. Type AB has both A and B antigens, which is why it is the universal recipient. Type O has neither A or B antigens making it the universal donor.

Tim Taylor, 2012) has argued that cardiovascular system referred to as the circulatory system, is composed of blood within the blood vessels and heart. The function of the heart is pumping the blood through the blood vessels of the body.

The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.

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, the workhorse of the body, has long been an object of fascination by civilizations. How does such a tiny muscle support the life of a human for such a long period of time? The answer lies within the physiology of the cardiovascular system itself. Simple one-celled organisms had one major problem when it came to the diffusion of oxygen, the oxygen required by a mammal for instance, would be much greater than the rate at which these cells could diffuse oxygen. Thus the need for a more efficient process was integral in the creation of cardiovascular system as we know it today. The ability of the heart to pump blood fast enough (and in continuous loops) allows for this absorption of vital nutrients in a prompt manner. However the common knowledge we have currently about the way this system works is a relatively new understanding. In the 17th century, an Italian anatomist named Marcello Malpighi observed the capillary exchange between interstitial fluid and blood. This idea was a radical one (p.463-464). Common belief at the time was that the cardiovascular system distributed both blood and air. Many had thought that blood was produced in the liver and was distributed through the veins and also believed that it was the arteries that distributed oxygen to the body. William Harvey disproved this belief when he discovered that that weight of blood pumped by the heart in one hour exceeds the weight of the entire body. He soon discovered the one-way loop in

Heart disease, commonly known as cardiovascular disease, consists of various conditions that affect an individual’s heart. The biological system involved in heart disease is the circulatory system, which delivers oxygen and food to all the cells of the body in order to remove waste and carbon dioxide (“Heart Disease”, N.d.). The circulatory system consists of the heart, lungs, blood, and blood vessels. These conditions affect blood vessels by narrowing or blocking their passage way to the heart, which can lead to numerous types of heart conditions. There are 3 major types of blood vessels, which are the arteries, capillaries, and veins. Once any of these blood vessels are affected, many heart conditions can arise. The various conditions include:

Chest pain is a symptom that can represent several different diseases from different organ systems. It is essential to determine which system is responsible for the pain and state the severity of the patient’s condition (Longo et al., 2011). When considering pain, there are eleven different criteria one must consider and evaluate. These include the duration of the pain, onset, localization, irradiation, character, intensity, alleviating factors, aggravating factors, triggering factors, regularity and accompanying signs (Longo et al., 2011). These are all useful in determining the etiology of the pain and taking the appropriate therapeutic steps. The causes of chest pain are divided into

The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist, and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava, the pulmonary artery and vein, as well as the aorta. The aortic arch lies behind the heart. The esophagus and the spine lie further behind the heart.
