The Circulatory System
The circulatory system is the system of the human body that is responsible for delivering oxygen, nutrients, and disease-fighting cells to the body’s organs and tissues. Parts of the circulatory system include the cardiovascular system, which consists of the heart, lungs, blood vessels, and blood, as well as the lymphatic system, made up of the lymph vessels, nodes, and lymph itself. The cardiovascular system brings oxygen and glucose to the body’s tissues in the blood and distributes white blood cells, which defend against disease. The lymphatic system produces and transports additional immune cells. The cardiovascular system is known as a closed system, meaning that the blood it carries is re-circulated, while the lymphatic system is open, meaning that the lymph, the clear fluid within, is able to exit its complex of vessels and enter the cardiovascular system.

Within the cardiovascular system are several important parts of the circulatory system. They include two major organs, the heart and lungs. Also part of this system is a network of arteries, which carry oxygenated blood away from the heart, and veins, which bring deoxygenated blood back to the heart to receive more oxygen in the lungs. Blood is also part of the cardiovascular system.
Blood is the fluid that transports the disease-fighting white blood cells, the oxygen-supplying red blood cells, and the fuel-replenishing electrolytes to the body’s various tissues. There are two systems for circulating blood. During pulmonary circulation, the deoxygenated blood that has been returned to the heart is pumped into the lungs, where it receives more oxygen, and then pumped back into the heart to be distributed throughout the body. Systemic circulation is the process by which the arteries take this blood away from the heart and deliver it to the body, only for the blood to be returned by the veins to receive a new supply of oxygen.
The lymph itself is the name for fluid traveling

    The main parts of the cardiovascular system are the heart, blood and the blood vessels (arteries and veins). The function of the heart is to pump blood around the body. The function of the blood is to supply nutrients and oxygen to the cell. The blood vessels (arteries and veins) role is to transport blood to and from the heart. However, the general function of CVS is to remove waste products such as CO2 and protect the body, for example the white blood cells in the body. “It also distributes heat around the body and assists in temperature regulation and helps regulate water.”…

    The blood then travel to the lungs where it will receive the oxygen to continue the process of circulation. Later, it drains out of the lungs via the pulmonary veins and then travels into the left atrium. While the blood is forced out through the aortic semilunar valve and into the aorta. The aorta and its branches carry blood to all the tissues of the body system. Reference, Essential of Human Anatomy and Physiology, 2012, by Elaine N.

    The heart in the circulatory system pumps blood into the lungs where the blood is oxygenated. The blood is then returned to the heart and the newly oxygenated blood is circulated to the rest of the body. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen.…

    The cardiovascular system which impacts deeply on human consciousness. The heart and the body’s blood-transporting network of arteries, veins, and smaller vessels form the circulatory or cardiovascular system. As blood is continuously pumped out from the heart and around the system in two circuits, it carries oxygen and vital nutrients to all parts of the body and removes harmful waste products from tissues.

    The heart is a muscular pump that makes blood around the body through a system of blood vessels (arteries, veins and capillaries). Blood carries dissolved oxygen to the body cells and at the same time removes the waste products of respiration (carbon dioxide and water). Blood is also important in distributing heat around the body, along with hormones,…

    Heart is associated to cardiovascular system, heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. The blood carries food and oxygen to the cells and carries away carbon dioxide and waste materials. The right hand side of the heart receives de-oxygenated blood from the body tissues, and pumps it to the lungs. The left-hand side of the heart receives oxygenated blood from the lungs and pumps it into the body, so that the oxygen can be delivered to cells.…

    Cardiovascular system means the system of heart and blood vessels of human body. The term “cardiovascular” is a combination of two word; “Cardio” and “vascular”. The term “cardio” is derived from “cardiac” meaning Heart and the term “vascular” means blood vessels. So the name itself indicates that cardiovascular systems is the system of heart and blood vessels. Cardiovascular system is also known as “Circulatory System”. Cardiovascular system is made up of three major components; Heart, Blood vessels and blood. The heart is a hollow muscular organ made of strong cardiac muscles. The heart can push the blood through the circulatory system with great force. In fact push of the heart is the major force that causes circulation of blood throughout human body. Heart is made up of three layers; Pericardium, Myocardium and Endocardium. Human beings, unlike other some other species, have a closed circulatory system which essentially means that blood does not come into direct contact with body tissues. Rather, the blood flows in restricted pathways…

    Oxygen is carried through the blood via capillaries and veins (cardiovascular system) and is entered into the body by breathing it in (respiratory system) it then travels down the lungs (as explained in the first paragraph) until it reaches the alveoli, its then diffused into the blood but due to oxygen not being able to dissolve easily, most of it is carried by the haemoglobin in red blood cells and then transported into the parts that need a supply of oxygen e.g. if aerobic respiration is being carried, the working muscles will need a good supply of oxygen to prevent fatigue and to allow them to carry on working for longer until a limiting factor. Without the cardiovascular system then the oxygen taken into the lungs via the respiratory system will have nowhere to be transported to which means the heart and other vital organs wouldn’t be getting their supply of oxygen, so it shows that both systems are linked together for either to actually work.…

    The Circulatory System is the main transportation for the body, made up of blood vessels, the blood and the heart. The blood is comprised of the red blood cells, white blood cells (lymphocytes and phagocytes which make up part of the immune system, engulfing invading pathogens), platelets which help the blood to clot preventing infection all transported around the vessels amongst the plasma.

    The systemic circulation is distinct from the pulmonary circuit, which only conducts blood between the heart and the lungs. Oxygen-rich blood from the lungs leaves the pulmonary circulation when it enters the left atrium through the pulmonary veins. The blood is then pumped through the mitral valve into the left ventricle. The arties branch into smaller arteries, arterioles, and finally capillaries. The deoxygenated blood continues through the capillaries which merge into the venules, veins, and finally the venacava, which drains into the right atrium of the heart. From the right atrium, the blood will travel through the pulmonary circulation to be oxygenated before returning gain to the systemic…

    The cardiovascular system is an organ system that distributes blood to all parts of the body. The cardiovascular system is a very important system in your body because it is the body delivery system for circulation of blood, which is made up of blood, blood vessels, and the heart. Cardiovascular can be compared to the muscular pump equipped with one-way valves, also a system of large and small plumbing tube where the blood travels through. The circulatory system is important because it transport important materials throughout the body such as blood and nutrient molecules. Without the circulatory system, major organs such as the heart and lungs would fail to work and the body would not receive oxygen.…
