VITAL ORGAN – KNOW YOUR HEART

The Human Heart is often considered to be the origin of emotions and love; it also does not resemble the Heart shape typically used to depict it. The biological functions are as elucidated below,
The human heart is about the size of a fist and weighs between 250 and 350 grams. It is located slightly left of middle in the chest, anterior to the vertebral column and posterior to the sternum. The human heart provides a continuous blood circulation through the cardiac cycle and is one of the most vital organs in the human body.

It is divided into four chambers: the two upper chambers are called the left and right atria and two lower chambers are called the right and left ventricles. Normally the right ventricle pumps the same blood amount into the lungs with each bit that the left ventricle pumps out. Physicians commonly refer to the right atrium and right ventricle together as the right heart and to the left atrium and ventricle as the left heart .

Cardiology deals with the study of human heart and its disorders

The heart muscles needs blood flow to supply oxygen to allow it to do work. When there is insufficient oxygen, the muscle starts to suffer, and when there is no oxygen, the muscle starts to die. Over a period of time, cholesterol buildup can occur in these blood vessels in the form of Plague.

This narrows the artery and can restrict the amount of blood that can flow through it. If the artery becomes too narrow, it cannot supply enough blood to the heart muscle when it becomes stressed. Just like muscle soreness experienced in our limbs while engaging in anaerobic (without oxygen) exercises, the heart muscle too will ache if it doesn't get adequate blood supply. This ache is called angina.

If the plaque ruptures, a small blood clot can form within the blood vessel and acutely block the blood flow. When that part of the heart loses its blood supply completely, the muscle dies. This is called a heart attack, or a myocardial infarction Heart attack is most often caused by narrowing of the arteries by cholesterol plaque and their subsequent rupture. This is known as atherosclerotic heart disease(AHSD) or coronary artery disease (CAD).

The risk factors for Coronary Heart Disease are Family history or heredity, Smoking, High blood Pressure, High cholesterol , Diabetes and Sedentary life style.

While heredity is beyond a patient's control, all other risk factors can be addressed to minimize the risk of developing coronary artery disease or decreasing its progression if already present.

Classic symptoms of a heart attack may include: Chest pain associated with shortness of breath, profuse sweating and nausea. The chest pain may be described as tightness, fullness, a pressure, or an ache. Unfortunately, many people do not have these classic signs. Other presentations of heart attack may include: Indigestion, jaw ache, pain only in the shoulders or arms, shortness of breath, or Nausea and vomiting.

This list is not exhaustive, since many times people can experience a heart attack with minimal symptoms. In women and the elderly, heart attack symptoms can be atypical and sometimes so vague as to be easily missed. The only complaint may be extreme weakness or fatigue.

So in case you have a risk factor for Heart Disease and experience any discomfort in your mid section in addition to what is indicated above, please take medical help without delay.

In spring I am gay in handsome array; in summer more clothing I wear; when colder it grows I fling off my clothes; and in winter quite naked appear. What am I?
