Problems with the blood of the focus of Arkan.
Blood - the fluid that circulates in the blood system of humans and animals and provides a vital activity of cells and tissues and performance of various physiological functions. The main function of blood is the transportation of gases: oxygen - from the respiratory system to the tissues, carbon - from tissues to the organs of respiration.
Blood carries the transfer of glucose, amino acids, fatty salts, acids and other nutrients from the digestive organs to tissues, and the end products of metabolism - urea, uric acid, creatine, etc. - to the organs of selection. Blood is involved in regulating water-salt metabolism and acid-base balance in the body maintains a constant body temperature. The protective function of the blood is carried out due to the presence therein of antibodies, antitoxins, lysine, and the ability of white blood cells (leukocytes) to destroy microorganisms and foreign bodies. The most important property of blood - clotting - protects the body from blood loss in case of wounds.
In 100 ml of blood contains 18 - 24 g of dry residue and 77 - 82 g of water. Water makes up more than half the mass of red blood cells and 90 - 92% of the plasma. Plasma contains intermediate and final products of metabolism. This salt, hormones, vitamins, enzymes.
Blood reflects a greater or lesser degree all the shifts in the functions of individual organs and systems and pathological processes developing in the body. When metabolic disorders, endocrine glands, liver and other organs, a change in blood chemistry. One of the major indicators - the level of hemoglobin in the blood, lowering his talks about anemia and some other diseases. Change in the blood of its various components (white blood cells, red blood cells, proteins, platelets, etc.) plays an important role for diagnosis and treatment of disease. Changes in the blood can be diverse, until its sudden increase in the number or decrease it.
Blood pathology associated with diseases of the blood system and hematopoiesis. The etiology of several diseases such as leukemia, remains unknown.
Blood pressure is the hydrodynamic pressure in the blood vessels, occurs because the heart pumped blood into the vascular system and vascular resistance.
The value of blood pressure in the arteries, veins and capillaries are different. It is an indicator of the functional state of the organism. Blood pressure undergoes rhythmic fluctuations, growing at reducing heart (systole) and decreased in the period of its relaxation (diastole). Every new piece of blood ejected heart stretches elastic wall of the aorta and central arteries. During the pause stretched cardiac arteries are narrowed and pushing blood through the arterioles, capillaries and veins.
In humans and animals (many mammals), the maximum systolic pressure is about 120 mm Hg. Art. and the minimum diastolic 70 mm Hg. Art. The difference between these two rates is called the amplitude or pulse pressure.
In humans, blood pressure is usually measured on the arm above the elbow with sfigromanometra.
Capillary blood pressure is below about 40 mm Hg. Art.
Venous pressure was measured directly, by entering into a vein needle connected to a manometer.
In humans, the blood pressure in the arteries of averages: the systolic (maximum) 115 - 125 mm Hg. Art.; diastolic (minimum) 70 - 80 mm Hg. Art. With age, these values are changing.
Persistent increase in pressure - hypertension, can cause many diseases (hypertension, nephritis, etc.) drop in pressure - hypotension, may be a physiological nature, accompanying a number of pathologies, or being independent disease. People prone to spikes in blood pressure should monitor it daily, sometimes twice a day.
Symbolic aspect. Sick and pale man, obviously with organ dysfunction blood, goes to the pool, next to Jesus in a blue tunic, he looks enlightened eye of the patient.
Divination aspect. Pay attention to the condition of the circulatory system, may have a pathology, watch out for pressure.
