Full explanation about blood pressure

All you need to know about high blood pressure hypertension.

1: first what is blood pressure?

-Is the blood pressure on the wall of blood vessels, whether the arteries or veins or capillaries.

-Vascular is divided into three main types:

1: the veins Arteries: the blood vessels responsible for transporting blood from the heart to all parts of the body.Arteries carry oxygen and Nutrients nutrients except pulmonary arteries Pulmonary Arteries.And Donna from veins high flexibility and that understand the wisdom of the creator Almighty being. and is the main artery is the AORTA and aorta which comes out directly from the left ventricle LEFT VENTRICLE.

2: Veins: veins blood vessels responsible for blood transfusion and assembled from all parts of the body into the heart directly to the right atrium RIGHT ATRIUM where venous network collects from the upper half of the body to give the upper vena cava SUPERIOR VENA CAVA and the lower half of the body INFERIOR VENA CAVA for. holds the veins CARBON DIOXIDE CO2, all except for the Pulmonary veins.PULMONARY VEINS.

There are veins in the same flexibility of the arteries.

3: CAPILLARIES the capillaries are tiny blood vessels and thin-wall up between alshrainih and venous network network.

This is a picture of the heart

Now that we know the types of blood vessels in the human body. "we know that the heart is the contraction Systol and made Diastol.And you can imagine that during the contraction of the heart it generates pressure on the aorta and also during the diastolic generates pressure on the artery but of course less contraction pressure. scientists found that human arterial blood pressure Arterial Blood Pressure is the ratio between the systolic pressure Systolic Pressure diastolic pressure Diastolic Pressure.The identified in human normal 110/70 to 120/80 and unit used in measuring Hely mmHg.Hallelujah.Heart contraction force flying mercury is heavier metal m and 20 cm.Don't say hallelujah, Lord of the worlds.

3: what is the wisdom of God Almighty in the flexibility of the arteries?

-Imagine me my brothers in God.The artery has turned into a hollow cylinder of glass is completely free of any kind of flexibility.Heart diastolic has the terrible power that we mentioned earlier.What do you expect to happen? will break the bottle because they simply will not tolerate this terrible pressure..But if this rubber roller.The heart diastolic.What would happen? will stretch the cylinder so you can absorb the pressure and will not have anything ...So are the arteries that God-given the flexibility to expand during contraction and deflation in case you do. ..

4: what are the factors that affect blood pressure?

Of course there are many factors.And the most important:

1: heart rate Heart Rate:

The higher the heart rate.The higher the blood pressure.This situation shows athletes and runners.As well as during sex and extreme fear.

2: the rate of venous blood flow VENOUS RETURN:

Any return of venous blood to the heart again ...The higher the rate, the higher the heart rate.Thus increases arterial blood pressure

3: side PERIPHERAL RESISTANCE: resistance

Any resistance to the passage of the blood capillaries.The higher the resistance.The higher the blood pressure.

4: contraction, diastole blood vessel DILATATION AND VASO VASO CONSTRICTION:

This is the main factor in the high and low blood pressure.As we talked previously about the flexibility of the arteries will talk about one of the most important examples in this topic ...The intense fear.In that case the adrenal gland to secrete adrenaline hormone ADRENALINE which stimulate the blood vessels to constrict.Here, the blood pressure rises.How to interpret those phenomenon? you should know the following:

-What is the pressure at the point?

* Pressure point is the force acting perpendicularly on a space surrounding that point.

Stands for pressure by the symbol P..And symbolizes the force F and symbolizes A symbol space

Permission

P = ---

Through this relationship, we find that the pressure

1: proportional to the strength of the heart contraction with size.

2: and inversely with the size if cardiac contractile force.

And I want to take care of the second point.

-In case the vessel constriction: the cut area.And thus increases the blood pressure and if contraction into the talk about them later is high blood pressure HYPERTENSION

-In the case of diastole blood vessel: more than cut.So less blood pressure. If increased diastolic get into the talk also about later is low blood pressure

HYPOTENSION

5: blood BLOOD VISCOSITY: viscosity

The higher the viscosity of the blood.The smaller the force.So less blood pressure.This situation is clearly reflected in the case of diabetics.With a high level of blood sugar.The increase of his wife.So less blood pressure.This affects the heart which had contracted the illness.Therefore we say Beware of devastating triple: diabetes, heart pressure. may God and you evil diseases.

Amaan.High blood pressure or HyperTension is known as

5: what is hypertension chronic? And what are its causes?

-A satisfactory result in the survival of blood pressure in chronically high rate.

-Chronic Hypertension causes:

1: alcohol.

2: smoking.

3: Obesity is one of the most serious factors leading to excess accumulation of fat in the arteries to lost flexibility and the ability to stretch and shrinkage in the case of partial contraction and diastolic.A condition called atherosclerosis ATHERO SCLEROSIS.

4: excessive salt intake: chemical composition of salt is NaCl. The care component is sodium.It represents about 70% of the leading causes of chronic hypertension.Because sodium by itself increases the OSMOTIC PRESSURE of salt hypertension and increase foreign EXTRACELLULAR FLUID fluids leading to chronic high blood pressure.

5: diabetes: we mentioned this already on blood viscosity.

6: Renin RENIN level: where enzyme alaldositron stimulating hormone ALDOSTERONE, which in turn hold salts thus increasing osmotic pressure and lead to high blood pressure as mentioned above.

7: pathological: related to kidney or heart diseases and vascular diseases. the most important reasons is the high level of alkalisiom which leads to an imbalance in the rhythmic heartbeat ARYTHMEA.It is one of the most serious reasons which may lead to death if not treated in time.

8: genetic causes: rarely have chronic hypertension is genetically but Ward

9: nerve: nerve leads to high blood pressure.

6: what is chronic high blood pressure?

-Chronic high blood pressure if not treated:

1: anginas.

2: anginas.

3: brain drain.

4: failed and a heart.

5: burst blood vessels if the ratio of its beauty is about 60%.

6: acute renal failure.

7: rupture, retinal fibrosis.

7: are there types of chronic high blood pressure?

-There are in fact two types.A primary and a secondary

1: the first PRIMARY HYPERTENSION

It represents about 95% of the cases and the result of all the reasons we have already except for the disorders.

2: secondary SECONDARY HYPERTENSION

It represents only 5% of the cases and is caused by disorders of the kidney or glands, or as a result of pregnancy and medications that lead to high blood pressure. or as a result of the anemia and certain blood diseases such as fever, for example, or as a result of cancerous tumors

7: what are the symptoms of chronic high blood pressure?

-Doctor measuring blood pressure and also examined the eye capillaries appear high in red.They said prove the existence of the disease.

The doctor-patient's question whether there was a genetic history of the disease.

-The doctor's analysis of the following:

1: level creatinine SERUM CREATININE: to check kidney function and also to find out the type of disease (primary or secondary)

2: the level of salts (sodium, potassium)

3: blood sugar level BSL

4: blood CHOLESTEROL cholesterol level and is one of the most dangerous types of triglycerides TRIGLECRIDES that lead to hardening of the arteries if more than normal.

And of course also therapist dub

-And of course we must change the way of life and stay away from salt and pepper final. and also refrain from eating food containing high fat and exercise.Etc..For better health.

-I would like to say that the chronic high blood pressure is easy and can be cured but can be omitted.
