  4. 4. BLOOD O Blood is composed of two parts, namely blood plasma (55%) and blood cells (45%). O There are three kinds of blood cells, namely 1. eritrosit, 2. leukosit, and 3. trombosit.
  5. 5. BLOOD PLASMA O Blood plasma or liquid composed of 90% water, 8% protein (consisting of albumin, hormones, globulin, prothrombin and fibrinogen), 0.9% minerals (consisting of NaCl, sodium bicarbonate, calcium, phosphorus, magnesium, and iron), and 0.1% organic matter (glucose, fats, urea, uric acid, amino acids, enzymes, and antigens). O Soluble protein in the blood is called blood proteins. O Blood proteins that are important include hormones, fibrinogen, albumin, and globulin.
  6. 6. Eritrosit OErythrocyte function to transport oxygen. OErythrocytes shaped flat, concave in the middle (bikonkav), and not core. Each 1 mm3 of blood containing ± 5 million erythrocytes. OErythrocytes containing hemoglobin (Hb) is a protein compound containing the element iron. OHb function carries oxygen from the lungs and circulate throughout the body. OErythrocytes formed by red marrow flat bones. After erythrocyte age ± 120 days, the cell becomes obsolete. OErythrocytes were overhauled by the liver and spleen. OIn the liver, hemoglobin is converted to dye bile (bilirubin). While the element iron in hemoglobin is used again to create new erythrocytes Eritrosit
  7. 7. Leukosit  Leukocyte function to kill germs and forming antibodies.  Leukocytes clear colorless, and its shape is not fixed like amoeba.  Each 1 mm3 of blood contained 8,000 leukocytes.  Leukocytes have 5 different forms, namely monocytes, lymphocytes, basophils, eosinophils and neutrophils.
  8. 8. Trombosit OPlatelets function to freeze the blood. OPlatelets are small, irregular, and not core. Each 1 mm3 of blood platelets are ± 250,000. OPlatelets have the enzyme Tissue factor. OIf the blood out of being hurt, then it will be broken platelets. OEnzyme Tissue factor out of platelets. OEnzim trombokinase keluar dari trombosit. OBecause of the influence of calcium ions in the blood, enzymes Tissue factor prothrombin to thrombin will change. OWould thrombin converts fibrinogen to fibrin threads. OThreads of fibrin cause injury covered and not bleed continuously. OProthrombin is a protein compound that is formed in the liver with the help of vitamin K.

  11. 11. BLOOD FUNCTION 1. As Tool Carrier a. Erythrocytes serves as a carrier of oxygen from the lungs to the heart and throughout the body cells;h; b. blood plasma transport: 1) nutrients from the intestine to the liver and then to the rest of the body; 2) carbon dioxide from the body tissue to the lungs; 3) urea from the liver to the kidney to be issued; 4) hormones from glands throughout the body's hormones; 2. Leukocyte function to kill germs. 3. Platelet function for blood clotting. 4. Maintain body temperature stability. The temperature of the human body 370C range, although the ambient temperature increases or decreased. This is because the energy spread heat evenly carried by the blood.
  12. 12. HEART OThe heart is located in the left chest cavity. A fist-sized heart, and hollow. OCavity of the human heart is divided into four parts, namely the right atrium, left atrium, right ventricle and the left ventricle. OHeart cavity wall is composed of cardiac muscle OHeart muscle to contract by way of inflation and deflation.
  13. 13. Blood Vessel O Blood vessels can be divided into two, namely the arteries (arteries) and veins (veins). O Arteries and veins are connected by capillaries. Blood pressure can be measured with a blood pressure meter (sphigmomanometer). O Blood pressure is a sign of the strength of the heart to pump blood and signs of a person's health. O Normal adult blood pressure 120/80 mm Hg (millimeters of mercury). Value of 120 indicates systolic pressure, while 80 indicates diastolic pressure
  14. 14. Nadi vessels (arteries) O Arteries are vessels that carry blood away from the heart. O Arterial blood stream that contains more oxygen. Artery lies somewhat hidden from the surface into the body. O Artery vessel wall which has a strong and elastic. Artery coming out of the left ventricle of the heart is called the aorta. O Aortic flow of oxygen-rich blood throughout the body.
  15. 15. O The aorta has a valve near the heart which serves to keep the blood does not flow back to the heart. O Artery coming out of the right ventricle to the lungs is called pulmonary artery. O Pulmonary arteries carry blood rich in CO2 O Carbon dioxide is released by the blood in the lungs, and oxygen captured by Hb. O Blood that has gained oxygen will flow to the heart through the pulmonary vein.
  16. 16. Behind vessels (VENA) OVeins are the vessels that carry blood to the heart. OVeins located near the surface of the body and appear bluish. OVeins have thinner vessel wall and not elastic. OVeins have valves along the vessel which serves to keep blood flowing in one direction toward the heart. OOf the whole body, all vein empties into a large vein called the vena cava. OVena cava blood flow rich in carbon dioxide from the body into the heart through the right atrium. OWhile the pulmonary veins drain blood rich in oxygen from the lungs to the heart.
  17. 17. Capillary Tubes OCapillaries are formed by a single layer of endothelial cells are very thin and serve for the exchange of substances. OTotal capillaries very much and the amount of surface area of 600 m2. OCapillaries are directly related to the body's cells and tissues to deliver oxygen and nutrients. OFurthermore, carbon dioxide, water and remnants of combustion is taken, to be transported to the lungs and other expenses tool.
  18. 18. Circulation of lymph system (lymph) OLymph circulatory system consists of lymph fluid, lymph vessels and lymph nodes (lymph node). OLymph circulatory system plays a role in fat distribution and the eradication of disease. ODuring the circulating blood in the capillaries, there is blood fluid that seeps out of the blood capillaries. OThe liquid fills the spaces between cells and is called tissue fluid. OLymph circulation duty to restore the tissue fluid into the blood capillaries. OTissue fluid which has been in the lymphatic vessels into a fluid called lymph (lymph). OLymph fluid containing leukocytes and fat. Fat that is absorbed by the intestine is not transported through the blood vessels, but by lymph vessels.
  19. 19. Lymph vessels OLymph vessel structures similar to small veins, but has a lot of valves so that the lymph vessels looks like a series of beads. OLymphatic vessels located in between the muscles, and has a smooth branch of the section ends open. Through this open end, tissue fluid into the lymphatic vessels. OLymphatic vessels can be divided into two kinds, namely the right lymph vessels and lymph vessels left Along the lymphatic vessels there are some lymph glands, especially in the groin, armpits, and neck. OWhen the body is exposed to infection, lymph nodes will swell. OThe function of the lymph glands to produce leukocytes and make sure to avoid spreading the infection further.
  20. 20. Circulation of lymph system (lymph)
  21. 21. In the body there is also a tool body whose function is similar to the lymph nodes, namely: O The spleen is a gland that is dark purple and located next to the rear of the hull. Spleen serves to: O where the formation of leukocytes and antibodies; O blood cell reservoirs. If any part of the body is deprived of blood, the spleen will spend its reserves; O where demolition erythrocytes dead; O tonsils and tonsil O Tonsil is located in the left and right of the larynx. O Tonsils form lymph glands known as tonsil. O Glands in the tonsils contain many lymphocytes. O In addition, the tonsils are also in the nasal cavity called polyps (nasal polyps). O Tonsils and polyps worked as a front line of defense of the body from infections that can spread from the nose, mouth and throat.
  22. 22. Abnormalities of the Circulatory System O Anemia O Leukemia O Hemofilia O Hipertensi O Arterosklerosis O Wasir (Hemeroid) O Varises O jaundice
