Mmene thupi la munthu limayambira ndilo gawo la mtima. Icho chimagwira ntchito yofunikira mu kuyeretsa kwa matupi a thupi ndi mu metabolism. Mosiyana ndi magazi, gawo ili silitsekedwa ndipo sagwiritsa ntchito mpope wapakati pa kayendetsedwe ka magazi. Madziwo amayenda pang'onopang'ono pansi pa chikoka chaching'ono.
Mmene thupi la munthu limayendera
Chigawo ichi cha thupi chimaphatikizapo:
- zotengera zofanana ndi capillaries zomwe zimachokera madzi;
- Zilonda zamphongo zomwe zikuphatikizidwa mu filtration;
- miyendo iwiri yamadzimadzi;
- ndi madzi omwe amazungulira mthupi.
Kuonjezerapo, ziwalo za thupi la munthu zimaphatikizapo thymus, tonsils ndi mpeni.
Pokhapokha m'pofunikira kunena za kapangidwe kake kamene kali ndi mimba. Imachita ntchito zofunika, zomwe zimapangidwa makamaka ndi dongosolo. Choncho, izi zimakhala ndi minofu ya lymphoid. Pachifukwachi amaimira mawonekedwe a maselo a plasma ndi reticulocytes. Ndi pa tsamba ili la dongosolo lomwe ma volume a B-lymphocytes akuwonjezereka, omwe amachititsa kuti chitetezo chikhale cholimba . Pakati pa kutembenuzidwa kwina, amapanga antibodies.
Pakati pa nthendayi iliyonse pali T-lymphocytes, yomwe, pokhudzana ndi antigen, imakhala ndi kusiyana kosiyana. Motero, ziwalozi za thupi zimathandizira kupanga mapangidwe a maselo.
Kuonjezerapo, nkofunikira kutchula momwe thupi limapangidwira. Madzi oterewa ndi mbali ya minofu yogwirizana. Lili ndi mchere komanso mankhwala othandizira mapuloteni omwe amapatsa mamasukidwe akayendedwe. Zolembazo ndi mafuta ambiri. Madziwo amafanana kwambiri ndi magazi a plasma.
Mu thupi la munthu aliyense ali ndi malita awiri a lymph. Kusuntha kwake kumachitika kudzera mu zombo chifukwa cha kusweka kwa maselo a minofu m'makoma. Udindo wofunikira pa nkhaniyi umasewera ndi ntchito ya minofu yoyandikana, kupuma ndi udindo wa thupi lonse.
Ntchito za lymphatic system
Mmene thupi limagwirira ntchito, ngakhale kuti likuwoneka kuti si lofunika kwambiri monga mchitidwe wamanjenje kapena wamagazi, komabe imathandizanso kuti thupi likhale loyenera:
- Chinthu chachikulu chimene chimachita ndicho kutsimikizira kuti madzi ndi zinthu zambiri zimachokera ku malo osungirako zinthu. Zonse izi zimalowa mitsempha ya magazi.
- Chitetezo cha thupi motsutsana ndi tizilombo tina ndi zachilendo. Pazigawo za dongosolo lino, zinthu zina zomwe zingawononge munthu zimachedwa. Zachigawozi zimakhala ngati zowonongeka zachilengedwe.
- Kuchulukitsa maselo a chitetezo. Apa, ma leukocyte apadera amapangidwa, omwe amalowa m'magazi. Ngati ndi kotheka, amapanga tizilombo toyambitsa matenda omwe amalumikiza ndi kuchepetsa tizilombo toyambitsa matenda.
- Mbali ina yaikulu ya maselo a thupi la munthu ndiwothandiza pa nkhani ya kuyamwa mafuta. Mapuloteni ndi zakudya zimalowa m'thupi mwa m'mimba. Ndipo mafuta ambiri amalowa m'zombo zam'mimba. Komanso, ndi madzi ofanana, iwo ali kale m'magazi.
- Kutumiza kwa mapuloteni akuluakulu ku zigawo zofiira. Zinthu zazikulu sizingathe kulowa mu capillary kuchokera ku malo osungirako zinthu. Ndipo ayenera kukhala mu dongosolo lozungulira - izi ndizofunika kuti mugwire bwino ntchito. Mapuloteni akuluakulu amapezeka m'magazi panthawi ya lymph, popeza ma capillaries omwe ali ofananawa amatha kudumpha zinthu zofunika.
Nkofunika kuti madzimadziwa asunthire, ndipo mulimonsemo, musalole kusamba. Mfundo yonse ndi yakuti ngati mliriwu umayenda pang'onopang'ono kuzungulira thupi, ukhoza kuyambitsa kutupa kwakukulu kwa nodes , zomwe zimafuna kuti achoke.
