Cardiovascular System Of The Human Body

Heart failure may convey that the heart isn’t working anymore, but what it really means is that the heart isn’t pumping as well as it should be (REF). Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood through to meet the body’s needs for blood and oxygen (REF). At first, the heart tries to make up for this by enlarging, developing more muscle mass, and pumping faster. As this happens, the blood vessels narrow to keep blood pressure up and the body diverts blood away from less important tissues and organs to maintain flow to the heart and brain (REF). Eventually, the body and heart cannot keep up and the patient begins to feel fatigue, breathing problems, weight gain with swelling in the feet, legs, ankles or stomach, and other symptoms that eventually leads to a hospital visit. The body’s coping mechanisms give us better understanding on why many are unaware of their condition until years after the heart declines (REF).

The prevalence of congestive heart failure is on the increase both in the United States and all over the world, and it is the leading cause of hospitalization in the elderly population. Congestive heart failure is a progressive disease generally seen in the elderly, which if not properly managed, can lead to repeated hospital admissions or death. Heart failure means that the heart muscle is weakened. A weakened heart muscle may not be strong enough to pump an adequate amount of blood out of its chambers. To compensate for its diminished pumping capacity, the heart may enlarge. Commonly, the heart's pumping inefficiency causes a buildup of blood in the

Veins are made up of more elastic tissue and less smooth muscle and carry blood to the heart from the body. The heart wall has three layers that surround the heart. The outer most layer is the epicardium, middle layer is the myocardium, inner layer is the endocardium.

People who have high blood pressure are putting more strain on the arteries, and this could be dangerous because it could lead to things such as heart attacks and strokes. Blood pressure can be measured by a sphygmomanometer.

Congestive Heart Failure is when the heart's pumping power is weaker than normal. It does not mean the heart has stopped working. The blood moves through the heart and body at a slower rate, and pressure in the heart increases. This means; the heart cannot pump enough oxygen and nutrients to meet the body's needs. The chambers of the heart respond by stretching to hold more blood to pump through the body or by becoming more stiff and thickened. This only keeps the blood moving for a short while. The heart muscle walls weaken and are unable to pump as strongly. This makes the kidneys respond by causing the body to retain fluid and sodium. When the body builds up with fluids, it becomes congested. Many conditions can cause heart

Congestive heart failure (CHF) is a syndrome that occurs when the heart cannot pump sufficient blood to meet the tissues metabolic and oxygen needs. As a result, intravascular/ interstitial volume overload and poor tissue perfusion occurs. An individual with heart failure experiences reduced exercise tolerance, a reduced quality of life and shortened life span. The most common cause of heart failure is coronary artery disease (CAD). The incidence of heart failure increases with age. Approximately 1% of people over the age of 50 and 10% of people over the age of 80 experience heart failure. The prognosis depends on underlying cause and response to treatment. Heart failure may be classified according to the side of the heart affected.

Heart failure is when the heart cannot keep up with the immense demands placed on it by the body, and it starts to compensate causing remodeling of the cardiac cells due to stronger cardiac contractions. The heart chambers expand so they can fill with more blood to pump to the rest of the body, and the heart rate will increase to meet these demands (American Heart Association, 2015). Heart failure is the inability of the heart to fill and pump effectively enough to meet the metabolic demands of the body resulting in pulmonary and venous congestion (Lam et al., 2007). Over time the body can no longer compensate, and the person becomes symptomatic and progresses into worsening heart failure. The pulmonary and venous congestion or “fluid overload” will manifest itself in the form of lower extremity edema, shortness of breath, fatigue and even chest pain, which interferes with quality of life (Colucci, 2015).

To conclude, congestive heart failure is a serious disease that happens when the heart is unable to work efficiently. Despite the fact that there is no cure for this disease, treatment are available if the disease is diagnosed early. Also, the symptoms can be controlled properly for many years. If the disease continues to progress without medication through the four main stages, the function of the heart will be severely affected to the point where life is no longer

Heart failure is a long-term (chronic) condition in which the heart cannot pump enough blood through the body. When this happens, parts of the body do not get the blood and oxygen needed for them to function properly.

Congestive heart failure is when the heart weakens and the heart cannot pump enough blood to the body, or enough oxygen to the lungs. The picture shows a healthy heart and the proper flow and a heart that has the condition congestive heart failure. You can see that the heart on the left is slightly bigger in a sense. The condition narrows the arteries in the heart causing it hard to pump blood throughout the body. The symptoms of CHF: shortness of breath when laying down, fatique and weakness, edema (swelling of any organ or body

“Congestive heart failure affects nearly 6 million Americans” (Congestive). It is a chronic progressive condition in which the heart does not pump enough blood, resulting in less oxygen and nutrients to the tissues and organs within the body. Congestive heart failure also known as CHF, is a disease in which the becomes weaker. CHF can cause failure of other organs of the body eventually leading to death. The heart circulates blood at a lower rate than normal causing heart pressure to increase. It often occurs that patients diagnosed with CHF may develop edema, a buildup of fluid in the tissues (Congestion).

Heart failure is a condition in which the heart muscle becomes too weak to maintain an adequate cardiac output to meet the body’s

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

The cardiovascular system is the system of the body which includes the circulatory system and your heart. This system has three functions. Its first is transportation where it is responsible for pumping blood to the organs, tissues, and cells of your body in order to transport a proper amount of oxygen and nutrients to every cell as well as remove the carbon dioxide and waste products made by some cells. This is done by using one of the strongest muscles and the hardest-working organ in the body-- the heart. Blood is pumped through this organ into the major blood vessels located at the base of the heart. The major vessels include the vena cava, aorta, pulmonary trunk, and the pulmonary veins. Although the heart is no bigger than the average

The cardiovascular system is comprised of the heart, blood and blood vessels its main function is to pump the blood around the body and get oxygenated blood to working muscles and deoxygenated blood to the lungs. The heart is a double pump which is split into two sides, the right side of the heart deals with deoxygenated blood while the left side of the heart deals with oxygenated blood. Bellow outlines the flow of blood around the heart.
