Definition, Function And Tips On Keeping Your Heart - Heart
(Latin, cor) is a hollow muscular organ that pumps blood through the blood
vessels by repeated rhythmic contractions. Means heart of terms related to the
heart, from the Greek word for heart cardia.
The heart is one of the human organs that play a role in the circulatory system.

anatomy of the Heart
The heart is located in the chest cavity. Heart size roughly
the size of a fist and weighing about 300 grams. heart in the circulatory
system to function as a blood pump.
The heart is composed of the heart muscle (myocardium).
Outside of the heart membrane coated with the lining of the heart
(pericardium). The pericardium consists of two layers. The outer layer called
the lamina panistalis and an inner layer attached to the heart wall is called
visceral lamina. Among this layer there is room perikardii perikardii cavity
filled with fluid. This fluid serves to withstand friction. The inside is
coated endocardium.
The heart has four chambers, namely:
atrium (left atrium),
dexter atrium (right atrium),
Ventricular sinister (left chamber),
dexter ventricle (right ventricle).
Antarsisi left and right heart are separated by a septum
(septum) in the form of solid muscle. Atrium heart of the room where the influx
of blood vessels (veins). Between the left atrium and the left ventricle is
valvula bicuspid valve (the valve leaves two). This valve prevents blood in the
left ventricle does not flow back into the left atrium when the heart
contracts.
Has a thicker ventricular muscle of the atrium, this
situation causes the ventricles pump blood out of the heart function. Between
the right atrium to the right ventricle valvula tricuspid valve (the valve
leaves three). This valve prevents blood from the right ventricle that does not
flow back into the atrium when the heart contracts.
Heart continuously pumps blood throughout the body. The
heart pumps the blood by way of the contract so that the heart can expand and
contract. This has led to the contraction of the heart beat that can be felt in
the arteries in some places.
When contracted, the atria and ventricles alternately
inflate and shoots. When the atrium expands, sucking blood from the heart
throughout the body via the blood vessels (the superior vena cava and inferior
vena cava). Blood is sucked into the blood from the right atrium and the
pulmonary vein is rich in oxygen into the left atrium.
When atrium furl ventricle expands and blood flows from the
atria to the ventricles. Ventricular function is part of the heart to pump
blood to leave the heart.
When shoots ventricle left ventricle, oxygen-rich blood is
pumped throughout the body, while the right ventricle in the CO2-rich blood to
the lungs pumping. After pumping out blood, loosens muscles and ventricular
relaxation experience so that the maximum heart pressure is very low. This
event is called diastole.
When blood into the ventricles, through His bundle
stimulation disconnected in less than a tenth of a second. This situation is
used by the heart muscle to rest. After that, the ventricular muscle buds and a
large amount of blood pumped from the ventricle into the pulmonary artery and
the aorta, this situation makes room for maximum heart pressure. This event is
called systole. Learning to carefully follow the work of the heart and blood
flow in the heart.
Cardiac function
Cardiac work through the mechanism of repeatedly and
continuously, also known as the cardiac cycle so as to visually see otherwise
known as heart rate. Through the mechanism of intermittent, heart berkonstraksi
for emptying the heart and relax to fill with blood.
In the cycle, doing systolic period is the period when
contracts and empties its contents (blood), and diastolic period is a period of
relaxation and filling of blood to the heart. Both loosen terrace and contract
simultaneously, and the two chambers also loosens and contracts simultaneously
conduct such a mechanism.
The cells of the heart muscle to contract for the purpose of
pumping blood triggered by action potentials and spread through the muscle cell
membrane. When the contractions, the heart into beating "rhythmic",
this is the result of actions taken by the potential of the heart itself.
The incident was caused by a heart have a mechanism to
create their own power to make the contraction or pumping and relaxation.
Mechanism of action of electricity that causes affected by several types of
electrolytes such as K +, Na +, and Ca ++. Therefore, when an interruption
occurs in the electrolyte levels in the body will cause disruption at the
mechanism of the flow of electricity in the human heart.
The heart muscle generates electrical currents and spread to
the tissues around the heart and delivered through the liquid contained by the
body. So that a small portion of this electrical activity reaches up to the
surface of the body such as on the surface of the chest, back, upper arm or
wrist, and this can be detected or recorded by using a special tool called
ElectroKardioGram (ECG).
So the ECG function is to record the electrical activity in
body fluids are stimulated by an electric current heart that appears to reach
the surface of the body. Various components of the ECG recording can be
correlated with certain processes within the heart. ECG can be used to diagnose
abnormal heart rate, heart rhythm disorders, as well as damage to the heart
muscle.
This is caused by the presence of electrical activity that
can lead to mechanical events, so that in case of abnormal electrical patterns,
usually accompanied by mechanical or human heart muscle is normal.
Each blood and oxygen the blood contains too many dirty
(carbondiocsida), of the entire body flows through two large veins to the right
ventricle. This happened after the right atrium filled with blood, which in
turn pushes the blood into the right ventricle. Are then pumped through the
pulmonary valve into the pulmonary artery leading to the lungs.
Pury pulmonary blood flow through vessels called capillaries
are very small, and the air bag in the vicinity of the lungs to absorb oxygen
and release carbon dioxide to draw blood into the pulmonary veins to the left
atrium stick. The circulation of blood in the right heart, lungs and the left
atrium called the pulmonary circulation.
When the blood in the left atrium and the left ventricle
pushed toward, da next will pump clean blood is passed through the aortic valve
went into aurta which is the largest artery in the human body. In the
oxygen-rich blood except the lungs, it is provided for the benefit of the
entire human body.
That Function Abnormal heart
If the decline in heart function, the performance of an
abnormal heart causing heart disease. There are several types of heart disease
caused by an abnormal heart function as follows:
1. Coronary Heart Disease
Is a blockage of the arteries that feed the heart muscle
(coronary arteries) due to deposition of fat and cholesterol. If the blood does
not flow at all due to a clogged coronary artery, the patient could suffer a
fatal heart attack.
2. Leaky Heart Disease
Is a condition in which there is a hole in the septum of
heart because of structural abnormalities of the heart. Broadly speaking, this
disease is a congenital disease. In the case of leaky heart, blood circulation
dirty blood circulation to the net so that the baby becomes blue. If too much
bad blood circulation blood circulation to clean and enter the vital organs
such as the brain, there can be difficulty breathing, accompanied by
convulsions, and even death.
3. Weak Heart Disease
Is a condition in which the heart can not pump enough blood
to the number of limbs. This is due to the greater heart muscle, so its ability
to pump will be rejected. This is one of the many consequences of high blood
pressure or hypertension.
It is some kind of disease that is caused due to a decrease
in heart function or abnormal.

heart health by preventing damage to blood vessels. Drinking two cups of
unsweetened green tea a day has been shown to have benefits to protect heart
health.
10. Night Sleep Quality
Research has shown that lack of sleep at night can cause
heart damage. Work commitments could make a number of hours of sleep at night

Sleep for 8 hours straight, some people may need more than 8 hours.
Sleep is when the body restore itself. If you have trouble
sleeping, try breathing exercises just before turning off the lights. People
who get enough sleep more controlled weight and have better health.
