What is heart?
Heart is vital organ of body and it play an important function of transporting of blood through out of the body. For the transport of blood in our whole body there are nerves called as blood vessels. Those blood vessels which carry blood towards the hearts are called as veins and those blood vessels which carry blood away from the blood is called as arteries.
Superior vanacava
And a large pipe which is called as superior vanacava transport the blood to uper wards of head and hand and lower pipe called as inferior venacava transport the blood to the lower part of the body like as abdomen and foot.
Structure of heart
Our heart weight is about human wrist but its small structure play an important rule in the transporting of the blood through out the blood and it is more below towards the lift lungs. And it is surrounding by double walwe called as pericardium.
Heart walwes
Our heart is separated by two walwes with the help of a wall called cardiac septum Our heart right part posses de oxygenated blood and lift part posses oxygenated blood. The wall (cardiac septum) separates their oxygenated and de oxygenated blood from the mixing to each other. Our heart is situated between our lungs.There are four chamber of our hearts as shown below. There are four parts of our body as given below.
Right atrium
Lift atrium
Right ventricle
Lift ventricle
Proses of oxygenation of blood
The blood coming from these parts of our bodies enter in the right atrium of our heart and this blood is de oxygenated there is a walve in the below of right atrium called tricuspid walve and this walve open only when right ventricle spread.There are four walve of this type in our body and these walve stop the extra flow of our blood and these are
Pulmonary wall
Trans cupid walve
Aortic walve
Lungs rule
When right ventricle spread then blood from uper right atrium comes in to right ventricle when this ventricle back contract the blood and in this way the blood from pulmonary artery and then enter in to the lungs where carbon dioxide is removed and oxygen is added in it now this oxygenated blood through pulmonary vein enter in to the left atrium and this blood does not go to the left ventricle until does not spread and there is also walve when left atrium contract this blood enter into the left ventrium through this wall.
Aorta
Then this blood enter in to a the called as aorta. Aorta transport the blood through out the blood with the help of the arteries. Aorta is the largest artery of our body. After the transport of oxygenated blood in to our body the de oxygenated blood is then enter in to the right atrium and in this way this cycle continue.
Heart disease
Coronary arteries transport blood to our heart and some times a condition occur due to which these arteries are blocked and blood passing through them stooped and in this cause following symptoms are occur
1-Chest pain
2-Breathing problem
3-Heart attack
This disease occur when patient eat more cholesterol and proteins foods are due to over stress and taking over weight.
Cholesterol foods
This condition occur when coronary arteries are blocked and blood cannot pass through them and this condition occur due to two reason first of all eating more cholesterol things and the second one is the injury in the coronary arteries in this time the blood passing through these aeries start accumulating in this area and in this way it is blocked and blood cannot pass through these arteries and as result these arteries are blocked and they cannot transport the blood through out the body.
Heart attack
And as result causing chest pain or heart attack. The patience of this disease are advice to inhibit taking high weight, eating more cholesterol es substances and taking more stress.
