Factors affecting blood pressure
Factors affecting blood pressure: Blood volume. Cardiac output Peripheral resistance. The elasticity of blood vessels. The diameter of the lumen of blood vessels. The viscosity of blood. Blood volume: it’s the total amount of blood in circulation. A sufficient amount of blood in blood vessels is necessary to maintain normal blood pressure loss of blood as in hemorrhage produces a fall in blood pressure. Cardiac output is the quantity of blood pumped by the heart in one minute. It’s the product of stroke volume and the heart rate. An increase in stroke volume increases systolic blood pressure. An increase in cardiac output increases both systolic and diastolic blood pressure. Peripheral resistance: is the resistance offered by blood vessels for the flow of blood. Resistance is offered mainly by small blood vessels, especially arterioles. Elasticity of the arterial walls distends the aorta when the ventricle contracts. The elastic recoils when the ventricle relaxes. This recoiled pushes the blood onwards. The decrease in elasticity as in atheroma produces a rise in blood pressure. 50 The diameter of the lumen of blood vessels: can be altered, narrowing of the lumen increases the resistance to blood flow and this increases blood resistance to blood flow and this increases blood pressure. Enlargement of the lumen has the opposite effect. The viscosity of blood: it’s the blood stickiness. The viscosity of blood spends on plasma, plasma proteins and number of the red blood cells. An increase in viscosity increases blood pressure.
Concentration on nada erase ‘bad karma’
Concentration on nada burns ‘bad karma’ Concentration on nada burns ‘bad karma’ – Bad karma’(sin) is destroyed by constant concentration on nada.

Disorders of Heart
Disorders of Heart Cardiac failure: It’s a condition in which the myocardium of ventricle is unable to maintain sufficient circulation of blood to meet the needs of the body. Depending on onset it may be classified into: 1- Acute failure: when it’s sudden. 2- Chronic failure: when it’s gradual. Stenosis of valves: it’s the narrowing of the valves of the heart. In this condition, the edges of the cusps of the valves become rough. So they stick together and narrow the valvular opening. The incompetence of valves: it’s a functional defect caused by the failure of the valve to close completely. This allows blood to flow back into the ventricle when it relaxes. Angina pectoris: it’s a pain occurring due to myocardial ischemia. It occurs due to narrowing of coronary arteries. Due to this, physical effort causes severe ischemic pain. Myocardial infarction: it’s the death of an area of cardiac tissue due to lack of coronary blood supply to the segment of the myocardium. It occurs due to occlusion of the coronary artery. Cardiac arrhythmia: it’s a disorder in cardiac rate and rhythm. It occurs due to defective impulses formation and defective impulse conduction in the heart.
