PEMBENTUKAN URIN / FORMATION OF URINE

PEMBENTUKAN URIN
    Unit fungsional dasar dlm ginjal ---- nefron terdapat 1-1,5 jt nefron
    Tiap nefron terdiri dari glomerulus dan tubulus ( proksimal, distalis,dll)
    Glomerulus membolehkan semua zat yg akan dieksresi dan mencegah hilangnya protein dan sel-sel.
    Tubulus proksimal --- mereabsorbsi dengan mengembalikan  ke aliran darah : asam amino, glukosa, asam urat dan sisa protein yang menembus  glomerulus
    Simplai henle ---- mereabsobsi air & natrium
    Tubulus distalis ---- mengatur konsentrasi ion-ion natrium,kalium, bikarbonat, fosfat dan hidrogen.
    Pengaturan akhir yang menyangkut  eksresi air dilakukan oleh ductus colligens.
Kecepatan filtrasi tergantung dr derasnya aliran darah, tekanan darah sirkulasi sistemik & tek darah ginjal






formation of urine
 basic functional unit within kidney nephrons are 1 to 1.5 milion---- nephron
 Each nephron consists of glomeruli and tubules (proximal, distal, etc.)
 glomerulus that will allow all substances excreted and prevent the loss of protein and cells.
 proximal tubules reabsorb --- by restoring the blood flow: amino acids, glucose, uric acid and the rest of the protein through the glomerulus
 Simplai Henle ---- reabsorb water and sodium
 ---- distal tubules regulate the concentration of sodium ions, potassium, bicarbonate, phosphate and hydrogen.
 Setting the end concerning water excretion by colligens ductus.
Filtration rate depends from swift flow of blood, the blood pressure of systemic circulation and renal blood.
