BLOOD PLEASURE


2/9

Blood pressure (BP) is the pressure exerted by circulating

blood upon the walls of blood vessels, and is one of the

principal vital signs. During each heartbeat, blood pressure

varies between a maximum (systolic) and a minimum(diastolic) pressure. The blood pressure in the circulation is

principally due to the pumping action of the heart. Differences

in mean blood pressure are responsible for blood flow from one

location to another in the circulation. The rate of mean bloodflow depends on the resistance to flow presented by the bloodvessels. Mean blood pressure decreases as the circulating

blood moves away from the heart through arteries, capillaries

and veins due to viscous losses of energy. Mean blood pressure

drops over the whole circulation, although most of the falloccurs along the small arteries and arterioles. Gravity affects

blood pressure via hydrostatic forces (e.g., during standing)

and valves in veins, breathing, and pumping from contraction

of skeletal muscles also influence blood pressure in veins.

Systole is a contraction of heart , driving

blood into the aorta and pulmonary arteries.

The occurence of systole is indikated by thefirst heart of sound heard on auscultation

(stethoscope and sphygmomanometer )

Diastole is the period between contractions

of the arteria or the ventricles during which

blood enters the relaxed chambers from thesystemic circulation and the lungs.

MEASUREMENT

The auscultatory method(from the Latin word for

"listening") uses a stethoscope and

a sphygmomanometer. This comprises an

inflatable (Riva-Rocci) cuff placed around the upper armat roughly the same vertical height as the heart,

attached to a mercury or aneroid manometer. The

mercury manometer, considered the gold standard,

measures the height of a column of mercury, giving anabsolute result without need for calibration and,

consequently, not subject to the errors and drift of

calibration which affect other methods. The use of

mercury manometers is often required in clinical trials

and for the clinical measurement of hypertension in

HYPERTENSION

Hypertension (HTN) or high blood pressure,

sometimes called arterial hypertension, is a chronic

medical condition in which the blood pressure in the

arteries is elevated. This requires the heart to work

harder than normal to circulate blood through the

blood vessels. Blood pressure involves twomeasurements, systolic and diastolic, which depend

on whether the heart muscle is contracting (systole) or

relaxed between beats (diastole). Normal blood

pressure at rest is within the range of 100-140mmHgsystolic (top reading) and 60-90mmHg diastolic

(bottom reading). High blood pressure is said to be

present if it is persistently at or above 140/90 mmHg.

In physiology and medicine, hypotension is

abnormally low blood pressure, especially in the

arteries of the systemic circulation. It is best

understood as a physiological state, rather than a

disease. It is often associated with shock, though not

necessarily indicative of it. Hypotension is the

opposite of hypertension, which is high bloodpressure. Blood pressure is the force of blood pushing

against the walls of the arteries as the heart pumps

out blood. If it is lower than normal, then it is called

low blood pressure or hypotension. Hypotension isgenerally considered as systolic blood pressure less

than 90 millimeters of mercury (mm Hg) or diastolic

less than 60 mm Hg. However in practice, blood

pressure is considered too low only if noticeable

symptoms are present.

I was very grateful to Allah and said

Alhamdulillah because I still had a healthheart that always beat well.

I was so amazed with heart work thatalways pumping the blood in the bodytrough blood vessels, espesially thecooporation of atrium and ventricle when

relaxation and contraction. It made aspecial rhythm of heart beat.

From this topic, I could learn and knowed how a heartwork and made blood pleasure (systole & diastole) in

my body

Then I learn from the scientist that made stethoscopeand sphygmanometer devices to help peoplesmeasured the blood pleasure. Altough I not madediscovery yet, I had to help others.

The last, I must took care my heart well, because thisorgan that gave by Alloh was very important in our lifeand health was expensive
