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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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.

20. 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.

21. 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.

22. Circulation of lymph system (lymph)

23. 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.
