Ntshav ntws rau hauv tus po via cov splenic cov hlab ntsha uas tom qab ntawd ceg mus rau hauv cov hlab ntsha trabecular. Ntshav cov hlab ntsha los ntawm cov nqaij dawb, hu ua pulp arterioles, txuas ntxiv rau hauv cov tawv nqaij liab li sheathed capillaries. Lub capillaries sheathed yog surrounded los ntawm macrophages thiab ib tug network ntawm reticular hlwb thiab fibers.
Ntawm no, dab tsi yog splenic ncig?
Lub sij hawm ' splanchnic ncig ' piav qhia txog cov ntshav ntws mus rau hauv plab hnyuv plab nrog rau lub plab, siab, tus po , txiav txiav, hnyuv me, thiab cov hnyuv loj.
Tsis tas li ntawd, cov lymphatic ntws los ntawm tus po? Tshooj ntawm ntshav uas nkag rau hauv spleen ntws intra-vascularly rau hauv venous sinuses, thaum lwm qhov ntws maj mam dhau cov lymphatic cov ntaub so ntswg thiab extracellular matrix ntawm pulp liab ua ntej mus txog cov hlab ntshav venous. Lymphatic capillaries thiab efferent hlab ntsha ua rau cov qog ntshav nodes sab nraum ntawm tus po.
Ib yam li ib tus tuaj yeem nug, tus hnoos qeev lim ntshav li cas?
Cov tus po ua si ntau lub luag haujlwm txhawb nqa hauv lub cev. Nws ua raws li ib tug lim rau ntshav ua ib feem ntawm lub cev tiv thaiv kab mob. Liab liab ntshav cov hlwb tau rov ua dua tshiab hauv tus po , thiab platelets thiab dawb ntshav cov cell tau khaws cia rau ntawd. Cov tus po kuj tseem pab tua qee yam kab mob uas ua rau mob ntsws thiab mob paj hlwb.
Cov ntshav ntau npaum li cas hauv tus po?
Hauv tib neeg, txog li ib khob (240 ml) ntawm liab ntshav cell muaj nyob rau hauv lub tus po thiab tso tawm thaum mob hypovolemia thiab hypoxia. Nws tuaj yeem khaws cov platelets thaum muaj xwm txheej ceev thiab tseem tshem cov platelets qub los ntawm kev ncig. Txog li peb lub hlis twg ntawm cov lymphocytes tau khaws cia rau hauv tus po txhua lub sijhawm.
