Thupi limapangidwa ndimadzimadzi. Maselo ake onse amakhala ndipo azunguliridwa ndi madzi. Kuphatikiza apo, malita anayi kapena asanu amwazi amayenda kudzera mumitsempha yamtima nthawi iliyonse. Ena mwa magazi amenewo amatuluka m'dongosolo momwe limadutsira m'mitsempha yaying'ono yamagazi yotchedwa capillaries yomwe ili munyama. Mwamwayi, pali "njira yachiwiri yoyendetsera magazi" yomwe imabwezeretsanso kutuluka kwamadzimadzi ndikuibwezera m'mitsempha.

Njira imeneyo ndi njira yama lymphatic. Imayenda mofanana ndi mitsempha ndipo imalowa mkati mwake. Mitundu ya Lymph pamlingo wochepa kwambiri. Mitsempha yaing'ono, kapena arterioles, imayambitsa ma capillaries, omwe amatsogolera ku mitsempha yaying'ono, kapena mitsempha. Lymph capillaries ili pafupi kwambiri ndi ma capillaries amwazi, koma sanalumikizidwe kwenikweni. Ma arterioles amapereka magazi kuma capillaries ochokera mumtima, ndipo ma venule amachotsa magazi ku capillaries. Magazi akamayenda m'mitsempha yama capillaries amakhala pamavuto. Izi zimatchedwa kuthamanga kwa hydrostatic. Izi zimakakamiza ena amadzimadzi omwe ali m'magazi kutuluka mu capillary kupita munthawi yoyandikira. Oxygen ochokera m'maselo ofiira am'magazi, komanso michere yamadzimadzi imafalikira mthupi.

Mpweya woipa ndi zinyalala zama cell mu minofu zimafalikira kubwerera m'magazi. Ma capillaries amabwereranso madzimadzi ambiri. Ma lymph capillaries amayamwa madzi omwe atsala.

Edema, kapena kutupa, kumachitika pamene madzi amkati kapena pakati pa maselo alowerera mthupi. Zimayambitsidwa ndi zochitika zomwe zimawonjezera kutuluka kwa madzi m'magazi kapena kupewa kubwerera. Kupitirizabe edema kungakhale chizindikiro cha mavuto aakulu azaumoyo ndipo kuyenera kufufuzidwa ndi katswiri wa zamankhwala.

Njira yama lymphatic imatha kutenga nawo gawo povutitsa khansa ya m'mawere.

Matenda amadzimadzi amasefa ma lymph akamadutsa. Amapezeka m'malo osiyanasiyana mthupi monse monga kukhwapa komanso kumtunda.

Kufalikira kwa mitsempha m'matumbo kumathandiza kuchepetsa madzi am'deralo komanso kusefa zinthu zovulaza. Koma mitsempha ya m'mawere ya m'mawere imathanso kufalitsa matenda monga khansa kudzera mthupi.

Zombo zam'mitsempha yama minyewa imapereka msewu waukulu womwe ma cell omwe ali ndi khansa amapita mbali zina za thupi.

Njirayi imatchedwa metastasis. Zitha kubweretsa kukhazikitsidwa kwa khansa yachiwiri ku gawo lina la thupi.

Mammogram iyi imawonetsa chotupa ndi makina amitsempha omwe alowerera.

Palibe mayi wachichepere kwambiri kuti adziwe kuti kudziyesa mawere pafupipafupi kumatha kuthandiza kupeza zotupa kumayambiliro awo, ndikuyembekeza asanafalikire kapena kufalikira.
