The circulatory feedback loop begins again when deoxygenated blood is received from the body and respiratory system, and then oxygenated blood is delivered throughout the body in a never-ending cycle. Blood pressure is the pressure on the blood vessel walls caused by the volume and viscosity of the blood circulating throughout them, as well as the strength of the heart contraction. The average blood pressure in a healthy young adult is approximately 120 mm during systole and 80 mm in diastole. As a person ages, the systolic pressure usually increases before an increase in diastolic pressure is noticed. Total health depends on the delivery of clean, oxygenated blood to the cells.
Many factors can interfere with the oxygenation of blood.
They include airborne toxins and pollutants, as well as poisons generated from within the body itself in the intestinal tract. Specific nutrients, especially those with antioxidant properties, can help the body remove these toxins. The proper use of herbs can help ensure your heart gets the nutrition that it needs. This diminishes the amount of oxygen which is supplied to the heart, and causes chest pain in a condition known as angina. This can be a preliminary warning to a heart attack.
