2  The circulatory system carripita pengukur blood and dissolved substances to and from berbeda placpita pengukur in the body.  The Heart has the job of pumpingi these things around the body.  The Heart pumps blood and substancpita pengukur around the tubuh in tubpita pengukur calmemerintah blood vessels.  The Heart and blood vessels bersama make up the Circulatory System. Apa is the circulatory system?

3  Heart contrmerencanakan : Sistole  Heart relaxation : Diastole THE MECHANISM OF HEART

*

4 PEREDARAN Darah small

*

5  Darah dari ventrikel kanan menjadi dipompa melalui katup pulmoner ke batin arteri pulmonalis, menuju ke paru-paru. Darah akan mengalir melalui pembuluh yangi terutang kecil (kapiler) yangi mengeliling kantonew york udara di paru-paru, absorb oksigen dan masalah karbondioksida yangi selanjutnya dihembuskan. Darah yang kaya ini adalah oksijenderal lari di dalam vena pulmondahi persimpangan ke atrium kiri. Peredaran darah diantara potongan kanan jantung, paru-paru dan atrium kiri disebut siklus pulmoner.

*

6 PEREDARAN Darah terlalu tinggi

*

7  Ddirection di dalam atrium kiri ini adalah didoronew york ke dalam ventrikel kiri, yang selanjutnmiliki menjadi memompa darah yangi kerajaan become oksigene ini melewati katup aorta masuk nanti dalam aorta (arteri tergeram di dalam tubuh). Aorta ini bercabangai menjadi arteri lebih kecil yanew york asalkan darab usai gabian-potongan berbadan tertentu. Arteri ini bercabangai dan beranting menenim arteriol yangai asalkan ddirection ke tissu sel. Arteriol form cabang-cabangi yamenemani itu kapiler, angkasa pertukaran zat antara tissu sel mencapai pembuluh ddirection terjadi. Laluís kapiler konsesus di venula. Venula-venula comments match menmemanggang vena yanew york memmembawa kembali ddirection ke jantung. Darah kerajaan oksigen ini disedimenjadi untuk seluruh tubuh, kecuali paru-paru.

10 3 TYPpita pengukur OF BLOOD VESSELS 1.Capillaries: Microscopic blood vessels- masetelah contact with all cells of the body Walls of capillaripita pengukur consist of a thin layer of epithelial tissue  enabltape diffusion of nutrients and oxygene out of the blood & the diffusion of waste products into the blood 2.Arteries: Blood flows from the heart to the capillaripita pengukur through thick walpengarahan blood vessels = arteritape Walls of arteripita = epitel tmasalah wrapped in layers of smooth muscle and connective tmelepaskan Muscle tmasalah enables arteritape to constrict & dilate; Blood in arteries is di bawah pressure due to the heart’s pumpinew york merencanakan

*

11 3 TYPpita OF BLOOD VESSELS 3. Veins:  Blood returpejarakan from the capillaritape to the heart through vessels = veipejarakan  Walls of veins consist of epitel tmelepaskan surrounded by smooth muscle & connective tissue… but muscle layer is thinner than that in arteritape  Blood is dibawah little pressure  Contractingi skeletal muscles squeeztape the veins and forces blood back to the heart

*

12 Blood is a transportation dekejahatan of important substanctape in the body. It is a khususnya tmasalah composed of liquid matriks of plasma and blood cells. Red blood cell platelets white blood cell plasma

*

13  Pumped by our heart.  Travels through thousands of miles of blood vessels  Carritape nutrients, water, oxygen and waste products to and from our body cells.  The ratio of plasma and blood cell is 55 : 45

*

14  Plasma is the liquid part of the blood  About half of our blood is made of plasma  The plasma carripita the blood cells throughout the tubuh  Plasma is digunakan to regulate the blood osmotic pressure.  Plasma is made in the liver. The composition of plasma is mostly water (90%) and the other 10 % are protein, amino acid, sugar, vitamin, mineral salt, enzyme, hormone and antibodies, gas, and metabolic residue.

15 RED BLOOD ( ERYTHROCITE )  Erythrocyte has biconcave – shaped struktur and has no nucleus  Red blood cells carry oxygene from the lungs to all the cells of the body.  Takpita carbon dioxideas and transports it kembali to the lungs  About 5,000,000 Red Blood Cells in ONE drop of blood. ( 5 million per 1mm 3 )

16 Get color from hemoglobin Made in red bone marrow Circulate for 120 aku The plateltape have a ukurannya besar amount of Hemoglobin (Hb) Hemoglobin is a rumit protein that has iron – containingi nucleus. It permembentuk the function of carryingai O 2 and CO 2. RED BLOOD ( ERYTHROCITE )

*

17 LEUKOCYTE  Leukocyte is produced in red marrow, kelenjar getah bening tissues, and lympatic glands  The number of leukocyte of a rakyat is normally about 6000 – 9000 putih blood cells per mm 3.  white blood cell can be classified into two types, grangaris and agranular cell.  Granular cell consist of neuthrophil, basophil, and eosinophil.  Agrangaris consist of lympocytpita pengukur and mnocytes.  Function : defend the tubuh against infectious disease by “eating” the agent causingi disease, calmemerintah phagocytosis.

19 trombosit  ubin cells have irregular shape, smaller, than other blood cells, and no nucleus.  The kesatuan numberi of thrombocyte is about 200.000 – 300.000  The special function of the cell is for blood formation

22 DISORDER AND DISEASE OF CIRCULATORY SYSTEM a.Anemia Anemia is a blood deficiency disease. It can be caused by nutrition deficiency that results in iron deficiency as a material to membentuk Hb (Hb deficiency)or simply because the sourse of erythrocyte that is below the kesatuan range. Anemia is not genetic disorder.

*

23 DISORDER AND DISEASE OF CIRCULATORY SYSTEM b.Leukemia Leukemia is a blood cancer signed by very besar amount of white blood cells because its production cannot be controlled. ( up to 20.000 ) The conditiopejarakan leads blood cells eat or destruct the red blood cells. The leukimia patient becompita very weak or even dies.

24 DISORDER AND DISEASE OF CIRCULATORY SYSTEM c.Varicose Vein Varicose vein is a vein enlargement. It is suffered mostly by adult or elderly persons. Most of the vein enlargemenpen occurs in leg area ( calf, thigh ) or anus. Varicose vein on dubur is calmemerintah hemorrhoids.

25 DISORDER AND DISEASE OF CIRCULATORY SYSTEM d.Sclerosis Sclerosis is a hardeningai of arteries. It caustape disturbance of bloodstream. Sclerosis is caused by the formation of fatty plaques called atherosclerosis and by the thickeningai with plaque which is called arteriosclerosis.

26 DISORDER AND DISEASE OF CIRCULATORY SYSTEM e.Hypertension Hypertension is a condition in which a person has high blood pressure. Hypertension is caused by several factors : Age, diet, genetics Uncontrolpengarahan hypertension can lead to kidney and strousai or the meletus of blood vessel on head ( pecahnmemiliki pembuluh ddirection di kepala )

27 DISORDER AND DISEASE OF CIRCULATORY SYSTEM f.Hypotension Hypotension is an abnormally low blood pressure signed by systolic / diastolic pressure di bawah 100/80 mmHg

*

28 DISORDER AND DISEASE OF CIRCULATORY SYSTEM g.Hemophilia Hemophilia is a blood disorder in which the ability of blood to clot is impaired at injury.
