  1. HEMOSTASIS AFRIWARDI

  2. HEMOSTASIS • DEFENISI : CEGAH HILANG DARAH • CARA : • SPASME PEMBULUH DARAH • BENTUK SUMBATAN TROMBOSIT • PEMBEKUAN DARAH • PERTUMBUHAN JARINGAN IKAT

  3. SPASME PEMBULUH DARAH REFLEK SARAF NYERI IMPULS ALIRAN DARAH KURANG KERUSAKAN JARINGAN PEMBULUH DARAH KONTRAKSI DINDING PEMBULUH POTENSIAL AKSI SPASME MIOGENIK

  4. BENTUK SUMBATAN TROMBOSIT • TROMBOSIT : • BULAT-CAKRAM • 2-4 MIKRON • DARI MEGAKARIOSIT • KONST. 150-300 RIBU/MM3 • WAKTU PARUH : 8-12 HARI • DIAMBIL MAKROFAG  T.U. LIMPA • MEMBRAN SEL : • GLIKOPROTEIN • FOSFOLIPID

  5. PEMBEKUAN DARAH • JALUR EKSTRINSIK • JALUR INTRINSIK

  6. JALUR EKSTRINSIK TRAUMA JARINGAN TROMBOPLASTIN JARINGAN FACT.VII FACT.X FACT.X ACT ION Cals. PROTROMBIN AKTIVATOR FACT.V PROTROMBIN TROMBIN

  7. JALUR INTRINSIK • SAMA EKSTRINSIK • PROTROMBIN AKTIVATOR • PROTROMBIN ROBAH TROMBIN • PENGAKTIFAN • FACTOR XII OLEH : • TRAUMA SEL DARAH • KONTAK DENGAN KOLAGEN

  8. PERTUMBUHAN JARINGAN IKAT • PROSES AKHIR • BENTUK JARINGAN IKAT • JARINGAN PERMANEN • KADANG : JARINGAN PARUT

  9. KEHILANGAN DARAH • AKUT : • HEMOSTASIS • KEHILANGAN : • VOLUME  GANGGUAN SIRKULASI • SEL DARAH  ANEMIA  GANGGUAN SIRKULASI • KONSTITUEN DARAH • KRONIS

  10. KOMPENSASI TUBUH • AKUT • HIPOVOLEMIA • HORMONAL  GINJAL • SARAF  BARORESEPTOR • KRONIS • SEL DARAH  ANEMIA  ERITROPOITIN

  11. TERIMA KASIH
