Healthy Heart Research Paper

The heart is located at the center of the chest, and is surrounded by the ribcage and protected by the breastbone. The heart’s main function is to keep blood continually circulating throughout the body. Arteries are the vessels that supply the body with oxygen rich blood; on the contrary the vessels that return blood to the heart are called veins. Like any other muscle in the body, the heart depends on a steady supply of oxygen rich blood. The arteries that carry this blood supply to the heart muscle are called coronary arteries.

The main organ of the circulatory system, and its ‘centre’, so to speak, is the heart, which is shown in the on the bottom right. Although the heart is not the largest of the body’s organs (the adult human heart is roughly the size of a clenched fist, and it only weighs about 310 grams), it is one of the strongest and, undeniably, the most important. The outer walls of the heart are made up of thick layers of muscle, which vary in thickness depending on where in the heart one looks - the muscle surrounding the left ventricle is much thicker than that surrounding the right ventricle, as the left ventricle has to pump blood further, and thus needs to be stronger. The inside of the heart is split vertically into two halves, separated by the septum, which each perform a distinct function: the right half receives the deoxygenated blood from the body and pumps it to the lungs, where it is reoxygenated, and the left half, which receives the freshly-oxygenated blood from the lungs, and pumps it to the rest of the body. These two halves are then ‘split’ horizontally into rough halves, leaving us with the atriums, which are the uppermost cavities, and the ventricles, which are the slightly larger of the two, located below the atriums.

The term pericardium is derived from the Greek prefix peri- (“around”) and kardia (“heart”), implying a structure that envelops or encloses the heart. Morphologically, the pericardium is a fluid-filled sac-like structure that surrounds the heart.

Cardiovascular diseases (CVDS) Cardiovascular diseases comprise ailments that include the blood vessels (veins, arteries and capillaries) or the heart, or together or diseases that disturb the cardiovascular system. The cardiovascular system, also named as the circulatory system, is the system that transports blood all over the human body. It is composed of the heart, arteries, veins, and capillaries.

A heart attack occurs when one or more arteries in the heart become blocked. The loss of oxygen damages the muscle tissue of the heart. When this happens, part of the heart muscle dies. The injured tissue does not contract as well and weakens the heart 's ability to pump blood. • Abnormal heart valves.

The correct side of the heart, including the correct chamber and ventricle, gathers and pumps blood to the lungs through the pneumonic conduits. The lungs revive the blood with another supply of oxygen. The lungs additionally inhale out carbon dioxide, a waste item. Oxygen-rich blood then enters the left half of the heart, including the left chamber and ventricle.

Christina Markevich 10/29/2015 Congestive Heart Failure What is Congestive Heart Failure? Congestive Heart Failure is something that occurs when the heart is no longer able to pump enough blood to the rest of the body, or when is just is not able to pump blood as well as it should. Some people happen to have either of these problems, some people have both.

CARDIO VASCULAR DISEASES Cardio vascular diseases (CVDs) are diseases of the heart and blood vessels. CVDs also constitute a major chronic disease, which is a leading cause of death not only in India but all over the world. There are many forms of cardio vascular diseases and many of them are interrelated. Some of the diseases are: i) Atherosclerosis ii) Heart attack iii)

Experts remedies highly effective best tips, Unhealthy heart signs Signs, symptoms of unhealthy heart – Symptoms of unhealthy heart The heart works in our body all the time. At the beginning of its failure, it reveals some symptoms, which people ignore. Your heart needs investigation as soon as these symptoms appear. Due to heart disease, do you have a problem of heart disease?

and lower the bad cholesterol (LDL). Many people can live with cardiovascular disease if they often exercise and eat healthy food.

The heart is a double sided muscular pump nestled between the two lungs in the centre of the chest, behind the breastbone. The muscular organ keeps the blood circulating around the body. The mammalian circulatory system is known as a double circulatory system because, on every circuit of the body, blood passes through the heart twice. The mammalian heart consists of four chambers: the right and left atria (singular atrium) and the right and left ventricles.

This is why medicine is often injected into veins rather than arteries or capillaries. This, in summary, is how the healthy circulatory system works. The heart pumps blood to the lungs where it is oxygenated, then the blood goes back through the heart into the arteries, which push the blood through blood vessels to carry it around the body, and then veins carry the blood back to the heart to be sent to the lungs again. In summary, that is how a healthy circulatory system operates. Atherosclerosis is a slow progressive disease that usually worsens in the victims 30s, but becomes dangerous in the 50s and 60s.

The contraction of the ventricles opens the semi lunar valves, forcing blood into the pulmonary and aorta arteries. The ventricles now relax (diastole) and any backflow of blood causes the semilunar valves to close (causing the second sound of the heart beat). Cardiac muscle never tires. The heart has its own

The heart is formed of two ventricles and two atria.(37) Each ventricle is cone shaped, with thick wall, pointed apex and broad base.(37) The two ventricles

Cardiac efficiency The idea of efficiency was developed in early 19th century with the development of steam engines. The total energy output of the system used to be less than the amount of energy input. The majority of the energy was used up in the form of friction and heat. With the advent of science the efficiency of the machines improvised but still it’s not possible for the machine to give 100% efficiency.
