Heart function and disease by Madduki

 

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. 

Liver functions and importance by Mudduki

Where liver occur liver

Liver occur in abdomen on the right side and on the top.  It is largest organ of our body and also it is vital organ of our bod. There are more than 500 function of our liver. 

Parts of the liver 

There are four lobs of the  liver as shown below

1-Right lobe 

2-light lobe

3-Caudate lobe

4-Guadrate lobe

5-Coronary ligament

Liver weight

The weight of the liver is about 1.5 kg in the abdomen.

Doctor advice 

If someone is the patient of the liver disease then doctor advice him to used the low foods such as lower energy foods so that there will be no need to control the liver disease because of the low eating. Liver function is more pivotal to our body if any disturbance occur in our liver our whole body is disturbed by this disease.

Functions of liver

There are following functions of the liver

1-Metabolic function

Proteins

Carbohydrate 

Fats

Vitamin 

Storage functions of the liver 

Vitamin A, B 12,D

Iron folic acid

Glycogen amino acid

The food we eat every day should be stored in some place so liver is the exactly that place where this energy is stored.

Synthetic functions

In our body should be a organ for the synthesis of specific things such as shown below

Glucose 

Protein

1-Plasma protein

2-Clotting factor

3-Hormone binding protein 

Steroid

All these nutrients are syntheses are by the liver and all of these are  pivotal for the body health.

Secreting functions

 Liver secret 

1-bile which is the important for the digestion and absorption of the food.

Liver Excretion

All things we eat and receive energy and for other other purposes. This is nature rule that every thing waste something for example from plants 

Plants undergoes to photosynthesis and produce water as the product of the photosynthesis and realse CO 2 as a waste product same as there are some things that must be undergoes to the excretion for example

1-Liver removes bacteria 

2-Liver removes virus 

3-Liver removes Toxins

4-Metals like arsenic, bismuth and lead

5- Bile pigment and cholesterol

All these things are dangerous or harmful for our body so liver excrete all these things from our body. Liver kill all these things with the help of the bile.  Bacteria are present in our food which we daily used if liver does not pay their rule then we can ill.

Heat production 

Liver also produce heat through the metabolism of the carbohydrate, proteins,  fats and the vitamins. Liver is the largest organ of our body which produce heat for different purposes that occur in our body. Heat quantity is more important for the purposes of the maintenance in different environments.

Hemopoetic function of the Liver

When we have not born at this time our liver is in active from and prepare the blood for our body.

1-In fetus liver produce blood cells

2-B 12 and folic acid for erythrocytes

3-Iron for hemoglobin

4-And promotes plat elates production

5-Red blood cells after 120 days of life span destroy in liver

Hemoglobin is the protein which is used for the clotting of the blood cells if an injury occur and in this case blood lost and in this time hemoglobin clot the blood  and in this way blood is saved So this protein is important protein.

In activation of drugs and hormones

Liver can inactivates the drugs and hormones.

It can also convert fat soluble medicines  to water soluble.

And can also inactive growth hormone such as growth hormone, insulin and the estrogen hormones.

Defense functions of the liver

1- Liver can kills the microorganisms such as bacteria

2-Viruses

3-Toxins

It also protect us from different disease and keep our health good. So liver is an important organ of our body.
