Pali chifukwa chomveka chofotokozera chifukwa chake amayi ali ndi misozi: kudyetsa ana. Koma bwanji matupi a anthu amasungabe zomwe zikuwoneka ngati ziwalo za thupi zochepa? Ndondomeko ya Darwin yachilengedwe ingawonekere kuti ziphuphu zamwamuna siziyenera kukhalapo. Kotero ndi chiyani chochita? Nchifukwa chiyani amuna ali ndi nkhono?
Chifukwa Chimene Amuna Amakhala ndi Zipsepse
Monga mazira m'mimba, amuna ndi akazi ali ndi ziwalo zofanana ndi ziwalo za thupi.
Ndipotu mazira onse amayamba ngati azimayi, chifukwa chake nkhono zilipo pakati pa amuna ndi akazi onse. Mwa anyamata, k chromosome ndi testosterone ya mahomoni zimabweretsa kusintha kwa mimba, kuphatikizapo kukula kwa mbolo ndi mapuloteni. Komabe, chifukwa nkhwangwa zatha kale asanakwatirane mwanayo atsimikiziridwa, zikopa zimakhalabe. Mitsempha imeneyi imakhalabe yogwiritsidwa ntchito.
Amuna ndi khansa ya m'mawere
Zikhulupirire kapena ayi, mawere aamuna amatha kupanga mkaka ndipo amatha kuyamwitsa khansa ya m'mawere . Ndicho chifukwa mlingo wina wa hormone wamkazi estrogen ulipo mwa anthu onse. Nthawi zina, chifukwa cha matenda kapena chikhalidwe chomwe chimakhudza mahomoni, minofu ya m'mawere amuna amatha kukula (matenda otchedwa gynecomastia ) ndipo amuna akhoza kupanga mkaka wa m'mawere.
Gynecomastia imawonekera kwambiri paunyamata, nthawi yomwe ikukula pamene mahomoni amasinthasintha kwambiri. Zikuwonekeranso mwa amuna ena omwe ali ndi matenda a chiwindi ndipo nthawi zina amamwa mowa.
Zina Zopanda Thupi
Ziphuphu zomwe zakhala zopanda ntchito chifukwa cha chisinthiko zimatchedwa "ziwalo zobisika," ndipo tili ndi zochepa. Nanga ndi ziwalo zina zotani zopanda ntchito? Nazi ochepa omwe mukanakhala mukuganiza kuti akanakhala okhudzidwa ndi chisinthiko:
Chiwombankhanga: Amuna ambiri ochokera m'mitundu yosiyana padziko lonse lapansi amachotsa chifuwa chawo pa mdulidwe.
M'mbuyomu, khungu limateteza mbolo ku matenda. Komabe, masiku amakono pamene anthu amavala bwino kwambiri, izi sizothandiza kwambiri, ndipo pali umboni wina woti khungu labwino limatha kukhala ndi kachilombo ka HIV.
Mavu: Pamene nsidze zanu zimagwira ntchito yofunikira pa maonekedwe anu, kodi munayamba mwadzifunsapo zomwe iwo akukwera pamwamba apo pamaso panu? Panthawi imodzi, makolo athu akale a mbiri yakale mwina anali ndi tsitsi lophimba nkhope yawo yonse. Ngakhale akatswiri sakudziwa kuti n'chifukwa chiyani nsalu zam'maso zili pamwamba pa maso, zisoti zimateteza kuti madzi asapitirire mvula kapena thukuta.
Nzeru Zomwe Zimayambitsa: Ngati anthu ambiri akungoyamba kuchitidwa opaleshoni, n'chifukwa chiyani anthu ali ndi mano a nzeru ? Nzeru za mano ndizozigawo zathu zachitatu, ndipo makolo athu adadalira kuti adye chakudya chophweka, monga masamba, mizu, mtedza, ndi nyama. Tsopano kuti chakudya chathu chamakono ndi chofewa ndipo tili ndi zida zambiri zomwe tingathe kuti tipeze chakudya chowopsya mosavuta, mano a nzeru si oyenera. Mmalo mokula ndi kutithandiza kudya, mano ambiri a anthu amatha kukhala mkati mwa nsagwada ndipo amatha kutsutsana ndi mano ena, kuchititsa mavuto omwe amawachotsa.
Mbali zina zamkati zimaphatikizapo tsitsi lakumwamba, zowonjezereka, ndi matani, zomwe zonsezi zingachotsedwe popanda kuthandizira thupi.
