2. The circulation of the blood (circulatory system) includes a tube of blood, heart, blood circulation of the blood pulse and blood pressure.1. Blood.
1.1 The definition of food, blood, blood is the body. Corpuscle consists of foods that nourish the body and the body does not want to lose that. Red blood in the arteries over time. And dark red. Over time, the vein A sticky liquid over the water about 5 times, bad taste, packaging only when blood flow in the tube has a temperature of about 100 (C or 37.8 (C-reactive a slightly alkaline. Blood in the human body is about 9 percent of body weight, or about 4500-5000 cc in men with body weight 50 kg
1.2 The components of blood. Blood is made up of two parts: a pool of blood (plasma) was 90% and leukocyte (corpuscles), which is 10%.
1.2.1 Water, blood (plasma) blood is the blood of a pale yellow clear liquid contains proteins, minerals, gas, food, hormones and other substances that are effective against the disease. Including waste. The body does not need.
1.2.2 There are three types of corpuscle.
(1) red corpuscle (erythrocyte or RBC), red corpuscle, flat, round shaped. There is no indentation in the center of the nucleus. If the single pill is yellow-green. If the combination is a red corpuscle, red iron. And of blood globin. (Haemoglobin) of this feature, when combined with oxygen to venous blood is red. (Oxyhaemoglobin), red corpuscle is made up of bone marrow (bone marrow) in male red corpuscle 5 million grains / cc and 4.5 million beads / ml in females is responsible for the oxygen from the lungs into the blood. red and carbon dioxide to the lungs.
(2) leukocyte (leucocyte or WBC) leukocyte has a different shape and size over the red corpuscle. One or more nuclei in one cell. There was a light gray or white. Leukocyte number in the body of a perfectly good, there are about 5000-7000 seeds / cc corpuscle is made up of the bone marrow. The lymph nodes act against bacteria and foreign matter that enters the body.
(3), platelets (thrombocytes) platelets are smaller than a red corpuscle. There is no nucleus. The bone cavity is about 2 million per 1 cc of blood, hard as it helps speed things up. With the power of the Turin Jane (fibrinogen).
1.3 Functions of blood. Are as follows.
1.3.1 Handling of food digestion and absorption throughout the body to the cells throughout the body.
1.3.2 transports oxygen from the lungs to the brain cells and get gas. Carbon dioxide from the cells to convey to the lungs.
1.3.3 Transport of waste to the transfer of organs such as kidneys, lungs and skin.
1.3.4 help maintain body heat.
1.3.5 allows the hormone to stimulate the body organs to function normally.
1.3.6 the body refreshed. And the fight against heart disease is an organ composed of two muscles that are outside the control of the mind inside the cavity. Shaped like lotus buds in a fist-sized, about 150-300 grams of a heavy indentation in the chest cavity between the lungs to the left and right sides. I have called the outer membrane. "Pericardium" in the left hemisphere is divided into two hemispheres with the right hemisphere. The left hemisphere of the red. The right side of the black blood collection. I have two rooms on each side of the upper and lower chambers. Between the upper and lower chamber room with a hole through the tongue to touch off the blood flow to the lower chamber.
