limfa tu kan salur yg mcm salur darah tuh..

klo xsilap..kepentingan limfa yg paling utama adalah utk mengembalikan semula cecair interstis ke dalam sistem peredaran darah..

cite psl sistem limfa ye..sy nih xpandai sgt trgkan tp sy cube yek >.<

darah dalam badan kita nih berada dlm keadaan tekanan tinggi akibat daya pengepaman jantung dan tekanan hidrostatik..ini akan menyebabkan sebahagian kandungan plasma darah meresap melalui dinding kapilari darah..pegi ke ruang antara sel.sume komponen bole merentasi dinding kapilari darah kecuali eritrosit,platlet ngn protein plasma.cecair yg berada di ruang antara sel ni dikenali sbg cecair interstis/bendalir tisu.

*pembentukan cecair interstis --> proses ultraturasan*

sebahagian besar cecair interstis (abt 90%) akan masuk balik ke dalam kapilari darah...selebihnya akan meresap ke dlm kapilari limfa.cecair yg masuk ni..name die limfa.limfa nih msti dikembalikn balik kt sistem peredaran darah..so gune sistem limfa.

limfa ni ade byk kapilari..klo korg rujuk buku teks/rujukan ade gambar die  kapilari limfa ni akan bersambung dgn salur yg lebih besar,name die salur limfa.spnjg salur limfa nih..ade nodus limfa.fungsi nodus limfa --> menghasilkn limfosit.dekat nodus limfa ni lar..bakteria akan cuba dimusnahkan oleh limfosit.nodus limfa ni plg byk kt perut,leher,dada n ketiak.spnjg salur limfa ni ade injap..biar one way je..

semua salur limfa akhirnya akan bercantum ngn salah satu drpd 2 salur limfa yg paling utama n paling besar iaitu duktus toraks n duktus limfa kanan.limfa dr sblh kanan kepala,kanan dada,tgn kanan akan mengalir ke duktus limfa kanan.lain2 pegi ke duktus toraks.

kandungn duktus toraks-->vena subklavikel kiri

kandungan duktus limfa kanan-->vena subklavikel kanan

dgn cara ini,cecair interstis dpt kembali ke sistm peredaran darah.tat's all.

fuh..pjg gak ek...sowe.. v.v korg phm ke?  sy ni xreti nk explain2
