Casual Articles - The Normal and Abnormal Heart
Many writing courses recommend outlining before writing, at least for non-fiction, especially writing for academic and professional audiences. Some, on the other hand, see initial outlining as constrictive and stifling of creativity and the free flow of ideas. There has even been some research on this subject, indicating that one size, in this case, does not fit all. For some writers, outlining first works best, and for some it is best to begin by getting key ideas and phraseologies (one might say one’s inspirations) down first before imposing that kind of organization. For many writers, a mixed approach works best, doing both simultaneously, or intermittently, carefully organizing an outline while stopping that to write down key
Heart Failure: This occurs when the heart is unable to pump blood effectively. Damage from heart attack is a common cause of this. The heart muscle can also become weak due to long standing high blood pressure, valve diseases and viral cardiomyopathy.
Other Cardiovascular Diseases:
High Blood Pressure: This is the single most important risk factor for stroke. It also contributes to the development of arteriosclerosis resulting in coronary artery disease and heart failure. It is commonly known as the "silent killer" as it usually does not cause any symptoms.
Stroke:Like a heart attack, stroke is a medical emergency and occurs due to interruption in the blood supply to the brain. It can occur due to thrombosis, embolism, or hemorrhage. It is the third leading cause of adult disability in the United States.
Peripheral Artery Disease: This affects about 8–12 million Americans. It is caused by blockage to the circulation going the legs due to plaque build up. It usually causes painful cramping
Everyday, there is a new EBay or Microsoft or Dell company that files for an IPO and that will make the early buyers of its stock very wealthy in several years. The trick is how to find them and invest in them safely. Sure a General Electric or Microsoft could possibly have a bump up in share price in one year of 30% or 40% with the release of a phenomenal product or service, but the chances of earning 70%, 100%, or even 300% in one year with large cap companies is quite slim. But it’s not so with small and micro cap stocks. In fact every month, there will be another micro or small cap stock that nobody has heard of that will make loads of savvy investors rich.So the key is how do you play riskier stocks like this? There
Throughout the history of mankind, the heart has attracted extraordinary intrigue as the emotional and spiritual home of the soul. Physicians are however compelled to look at it as a muscle and blood machine - an engine with staggering strength and stamina - one that holds together and keeps alive our own personal universe - our body.
The normal heart is a strong, muscular pump that continuously pumps about 2000 gallons of blood through the circulatory system each day. It does so by beating about 100,000 times. per day. It is about the size of your fist.
The heart has four chambers and four valves. The upper two chambers are the right atrium and left atrium - these collect the blood as it enters the heart. The lower two are the right ventricle and left ventricle - these pump blood out of the heart. There are two heart valves on each side. The mitral and aortic valves are on the left side and the tricuspid and pulmonary valves are on the right side. The valves open and close to let the blood flow in only one direction.
Right atrium: The blood returns to the heart after circulating through the body to this chamber. This dark bluish blood is brought back by two large veins called the vena cava. The right atrium holds the blood till the tricuspid valve opens and the blood then flows into the low pressure right ventricle.
Tricuspid valve: This is located between the right atrium and the right ventricle. It is a three leaflet valve that opens one way allowing the blood to flow into the right ventricle from the right atrium.
Right Ventricle: The right ventricle receives the deoxygenated blood and pumps it through the pulmonary valve into the pulmonary arteries which fan out in the lungs. As the blood circulates through the lungs, it receives fresh oxygen and becomes bright red in color.
Pulmonary Valve: This lies between the right ventricle and the main pulmonary artery. It prevents the blood from flowing back into the right ventricle.
Left Atrium: The oxygenated blood from the pulmonary veins comes to the left atrium. The left atrium holds the blood till the mitral valve opens and allows it to enter the high pressure left ventricle.
Mitral Valve: Unlike the other three valves, the mitral valve has two leaflets. It lies between the left atrium and the left ventricle and allows the blood to flow one way into the left ventricle.
Left Ventricle: The oxygen rich blood is pumped out by the left ventricle to the rest of the body via the aorta through the aortic valve.
Aortic Valve: This lies between the left ventricle and the aorta. The aorta is the main artery that sends the blood to the rest of the body. As with other valves, it allows the blood to flow in only one direction - from the left ventricle to the aorta.
Coronary Arteries: The heart itself must receive nourishment for its function. Oxygen and nutrient rich blood comes to the heart muscle via the right and left coronary arteries.
Vena Cava: These bring the oxygen poor blood from the body back to the right atrium.
Pericardium: The pericardium is a double walled sac that surrounds the heart and the roots of the great vessels. It anchors the heart to the surrounding tissues and prevents it from overfilling. Serous fluid inside the sac provides lubrication and prevents friction from occurring during heart activity.
Common Heart diseases:
“The heart is the only broken instrument that works.” T. E. Kalem
Coronary Artery Disease: This is the most common cause of cardiovascular disease and death. It arises from blockage of the coronary arteries that bring oxygen and nutrient rich blood to the heart for its own nourishment. Atherosclerosis is the main cause of this disease, and its resultant symptom of angina. Heart attack and sudden death are often the first and only symptoms of this disease.
Arrhythmia: Disorders of the heart beat are called cardiac arrhythmias. Atrial fibrillation affects over 2 million Americans. There are many different kinds of heart rhythm irregularities. Some may occur in a healthy heart and be of minimal consequence. Others may indicate a serious problem and lead to heart disease, stroke or sudden cardiac death.

Most of us have one common dream and that is to earn money, own a luxurious house, drive fancy cars and possess all those electronic gadgets that make our life comfortable. We keep striving throughout our life to acquire all these but some of them still remain unfulfilled because of our limited income. We often think that if we could supplement our income by having some extra source, as with the time our needs also grow. And for all our life we keep trying to establish a balance between our needs and our capability (read it cash ability) to fulfill those needs. But in the global economic scenario of today’s market, things are easier to achieve if planned pragmatically and meticulously.Home based business is one

Often times someone is unable to pay their mortgage payments due to a various number of reasons. This may be preceded by the lender foreclosing on the property. This article will look at the said foreclosure process.So what is a Foreclosure?A foreclosure process allows a lender or bank to recoup the amount that is owed to them on a delinquent loan by the process of selling or taking ownership (repossession) of the property that is securing the loan. The foreclosure process begins when a borrower or owner defaults on their loan payments and the lender files a default notice on public record, this is called a notice of default.The foreclosure process can hopefully conclude one of four ways: The receiver or owner ca

Do you remember the Little Red Hen? She wanted to bake some bread. She asked some friends to help with the various tasks, such as harvesting the wheat, taking it to the gristmill, gathering the ingredients, and making the dough. All her friends refused. The Little Red Hen replied “Then I will do it myself.” On the day when the delicious smell of freshly baked bread wafted out of the Little Red Hen’s kitchen, her friends arrived, asking for some. The Little Red Hen flatly refused to share her bread, of course.Although we can admire the Little Red Hen for her industriousness, we can also wonder why her attempts at delegation and teamwork failed. The Little Red Hen wasn’t a leader. She didn’t know how to create a team or

Peripheral Artery Disease: This affects about 8–12 million Americans. It is caused by blockage to the circulation going the legs due to plaque build up. It usually causes painful cramping in the hips, thighs or calves on exertion, and it goes away on resting. This is called "intermittent claudication". People with this disease have a six to seven times higher risk of heart attack or stroke.
“One of the hardest things in life is having words in your heart that you can't utter.” James Earl Jones. However when it comes to sickness, the heart is often unable to let you know until it is too late. So be kind to your heart - live and eat healthy.
