Fills in the human and animal arteries, with many important task liquid. Blood is essential for life. The most urgent task, of lung tissue to the metabolic events required to carry oxygen. Humans blood, a complex environment where many of the cell is alive. Her body weight is assumed to have the 70 milliliter of blood. According to this account 70 kg. ness in a normal adult is approximately 5000 (5 liters) of blood will be found. Blood, heart pumps a task that is circulating in a closed system. Between this system and heart with heart and lung tissue between the two is the part. The first in the "Great circulatory system", the second, the "young blood circulatory system" is called. Vein from the blood, the heart is poured into the right atrium. From here the blood into the right ventricle, the heart is the way to the lungs to tighten. Left ear-cleaning of the blood in the lungs heart comes out. After passing into the left ventricle then is pumped to the body. While releasing the oxygen from the blood vessels kılcai and to meet the need for oxygen and carbon dioxide alır.Dokuların at other residues, blood has many other more important task. Food items carry. Vitamins, enzymes and hormones required to go to reach the place provides. At the same time, the body's defense against infection has an important role. While the fight against an inflammatory condition, some blood cells are directly trying to destroy germs, the germs of others are inefficient makes antibodies. Another important task of blood and also to provide internal stability. "Homeostazis" the name given the small changes in this balance, the body reveals the dangerous situations. Adjust the body temperature plays an important role in the blood. The metabolism of body heat quickly, while satıhdaki of vessels available. By the same blood, the substances in the body provides sıvıelektrolit balance. The composition of human blood: It looks like a collection of fluid in the blood is also a body tissue. The tissue between the body tissue is different from other substances to form a liquid is. To this liquid "plasma" is called. Plasma (blood water), will constitute 55% of the blood. The remainder "of erythrocyte (erythrocyte) of leukocyte (leucocyte) and clotting role the" platelet "lerden has occurred.
Blood cells can be easily separated from the plasma. Rotating devices, which provided high Santriftij by rapid blood cells can be collapsed to the bottom, are separated from plasma. Blood viscosity (stiffness of the) water 5-8 times a certain part of the blood is renewed fazladır.Hergün. Red blood cells (erythrocyte), the blood after 30-40 days, the age of the erythrocyte (red blood corpuscle) and spleen, blood from the kill. Approximately 1% red blood cells until you kill, where the same amount of bone marrow cells from the blood is young. At the slightest changes in plasma volume is almost balanced. Blood loss volume of the body immediately with the balance mechanism will work hard to keep. First, the transition becomes tissue fluid from the blood. Then you will begin to rapidly give the young erythrocyte kana. Large amounts of shock occurs when blood is lost. Rather than shock the blood does not disappear status can not be circumvented.
