The Cardiovascular System Of The Body 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

system where the heart is the pump, which pumps the blood, and the blood vessels are

The cardiovascular system is formed by the heart and the vasculature, a close system of vessels, which include arteries, arterioles, capillaries, venules, veins and lymph vessels.

The human body roughly consist of 1.5 gallons of blood. Blood is a red liquid that circulates throughout the body through arteries and veins. This red liquid is pumped through the arteries and veins by the heart. Cardio- is a prefix that means heart. So, putting two and two together, the cardiovascular system pertains to the heart. The following essay will break down how the blood and heart function in the body.

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

The cardiovascular system contains the heart. As a kid you were told that your heart is about the size of your fist, this saying is actually true. The heart is one of the most important organs out of our whole entire body. The heart’s job is to pump blood throughout the body. This system also contains blood vessels. These blood vessels include the veins, arteries,

Cardiovascular system consists of the heart and it’s associated blood vessels. “Main functions of the cardiovascular system include the supply of oxygen and nutrients to all cellular tissues in the body while also removing metabolic wastes such as carbon dioxide” (Collins, 2013 p. 169). The heart is a four-chambered organ with two superior atria and two inferior ventricles. There is four valves located in the heart each function to prevent the backflow of blood into either atria or ventricular chambers. “The two valves located between the atria and ventricles are called atria-ventricular valves, while the two valves located between the pulmonary, aortic arteries and the ventricles are called semilunar valves” (Christensen & Kockrow, 2014 p.

The cardiovascular system consists of the heart, which is a muscular pumping device, and vessels called arteries, veins, and capillaries (Silverthorn, D.U, et al. 2016). The heart pumps blood around a closed unit of vessels as it passes through circulations of the body.

The cardiovascular system is also known as the circulatory system, which is an organ system that encompasses the heart and blood vessels of the body. The heart and blood vessels of the circulatory system adapt to repeated sessions of exercise in number of ways, the cardiovascular system carries blood, oxygen and nutrients to the organs and tissues of the body and carries waste products and carbon dioxide from these tissues to be removed from the body.

The cardiovascular system is a network of inter-connected arteries, capillaries and veins that spread across the whole body. The first major function of the system is to transport oxygenated and de-oxygenated blood throughout the body, the former to tissues and organs and the latter to the respiratory organs. The second is to deliver nutrients that are needed by different cells and tissues, and remove waste products and harmful chemicals generated or present in cells and tissues. (1) Cardiovascular disease (CVD) is one of the major contributors to mortality globally, taking up half of the 36 million annual deaths from non-communicable disease. (2) Actions can be taken to avoid the many deaths from CVD, in particular the improved address to CVD risk factors and access to medical care. (3) The aim of the study was to gain an understanding in the cardiovascular responses – in terms of changes in heart rate and blood pressure – produced under different types of stress in the form of a change from supine to erect posture, a cold pressor test, and an isometric handgrip exercise.

The heart is further composed of left and right atriums, arteries, veins, ventricles, valves, and other main parts (National Geographic, “Heart,” 1996). Another part of the cardiovascular system is blood. Blood is a bodily fluid that runs through the veins, arteries and capillaries to help the cardiovascular system perform its job (National Geographic, “Heart,” 1996). On average, adults have about 5 litres of blood. Blood is the stream in the human body that takes part in the transportation of oxygen and nutrients, and filtering out waste products (The American Society of Hematology, “Blood Basics,” 2016). Other functions of blood are protection of the human body by forming blood clots to avoid blood loss, fighting of infection through cells and antibodies, and the regulation of body temperature (The American Society of Hematology, “Blood Basics,” 2016). The blood is also composed of certain materials. The blood is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (The American Society of Hematology, “Blood Basics,” 2016). The last main part of the cardiovascular system is blood vessels. Blood vessels are tubes in the system that carries the blood (BBC, “The Circulatory System,” 2014). The three types of blood vessels are arteries, veins and capillaries (BBC, “The Circulatory System,” 2014). Arteries transport blood away from the heart (BBC, “The Circulatory System,” 2014). Veins

“Homeostasis comprises the dynamic processes that enable optimum conditions to be maintained for cells, in spite of continual changes taking place internally and externally” (Doherthy & Foudy, 2006, p. 26). I chose the cardiovascular system based on the fact that blood has to circulate to all of the other systems to help keep tissues and organs functioning. The organ of the cardiovascular system is the heart and the system also has arteries veins, and capillaries which are the blood vessels. The main tissues that are in the cardiovascular system are the epithelial tissue, muscle tissue, nervous tissue, and connective tissue. The cells that are associated with this system are red blood cells, white blood cells, platelets and then plasma a

The heart consists of many major functions. It transports nutrients, gases and waste products. The cardiovascular system works linking all the parts of the body to some type of artery or vein. This allows non-stop movement to deliver and eject nutrients, gases and waste products through the body. It pumps 5 to 6 liters of blood per minute through your body and can pump as many as 30 liters per minute during times of extreme stress. The cardiovascular system works with the respiratory system to deliver oxygen to the tissues of the body and remove carbon dioxide. In order to do this effectively the cardiovascular system is divided into two circuits, known as the pulmonary circuit and the systemic circuit. The cardiovascular system also maintains

Circulatory system comprises of two main systems. One is cardio vascular system and the other is lymphatic system. The lymphatic system comprises of a fluid known as lymph that circulates within lymphatic nodes, vessels, organs and tissues. Cardiovascular system is also known as vascular system or circulatory system. It functions to circulate blood through out the body and to supply nutrients to maintain homeostasis. The circulated blood transport nutrients and electrolytes for example oxygen, carbon dioxide, and hormones to meet the requirements of the body.

The cardiovascular system is an organ system that allows blood to circulate and is in charge of transporting oxygen, as well as carbon dioxide, hormones, nutrients, and cell waste items all over the body (Pironet, et al., 2016). This system helps to regulate body temperature, maintain homeostasis, and fight diseases. The cardiovascular system is made up of the heart, blood vessels, blood and plasma of the blood, and cells.
