Chifukwa chakuti chimayamwa mosavuta m'thupi ndipo chimakhudza mwachangu mitsempha, mowa ukhoza kubweretsa kupumula, chisangalalo, komanso kuchepa kwa mgwirizano. Komabe, kupatulapo zotsatira za kanthawi kochepa izi, thupi—makamaka chiwindi—likugwira ntchito molimbika kuti lithetse ndikuchepetsa mowa. Chiwindi ndiye "fakitale yayikulu ya mankhwala" yomwe imayang'anira… Werengani zambiri

Udindo wa Endorphins mu Kuchepetsa Ululu Ululu ndi wokumana nawo mwa anthu. Ungachitike chifukwa cha kuvulala, kutupa, matenda osatha, kapena kupsinjika maganizo. Ngakhale kuti ululu nthawi zambiri umaonedwa ngati chizindikiro cha ngozi, kwenikweni ndi gawo la chitetezo cha thupi, chomwe chimatithandiza kuzindikira mavuto ndikupewa kuwonongeka kwina.

Zotsatira za Hormone Yokulira pa Kukula kwa Thupi Hormone yokulira (GH) ndi imodzi mwa mahomoni akuluakulu omwe amachititsa kupanga thupi la munthu kuyambira ubwana mpaka kukula. Imapangidwa ndi pituitary gland, yomwe ili pansi pa ubongo, kenako imatulutsidwa m'magazi kuti ikakhudze minofu yosiyanasiyana. Ngakhale nthawi zambiri imagwirizanitsidwa ndi kutalika,...

Njira Yopangira Uric Acid Uric acid ndi imodzi mwa zinthu zomwe zimapangitsa kuti purine metabolism ichitike mwa anthu. Mankhwalawa nthawi zambiri amakambidwa chifukwa kuchuluka kwa uric acid m'magazi kungayambitse hyperuricemia ndikupangitsa kuti gout ndi impso zipangike. Komabe, uric acid si chinthu choopsa kwenikweni—pamlingo wabwinobwino, ndi gawo la njira za thupi, … Werengani zambiri

Kufunika kwa Iron pa Kupanga Hemoglobin Iron ndi mchere wofunikira womwe nthawi zambiri umanyalanyazidwa, ngakhale kuti ndi wofunika kwambiri m'thupi. Ntchito imodzi yofunika kwambiri ya chitsulo ndikuthandizira kupanga hemoglobin, gawo lalikulu la maselo ofiira amagazi omwe amayang'anira kunyamula mpweya.

Ntchito ya Maselo a T mu Chitetezo cha Mthupi Chitetezo cha mthupi cha munthu ndi njira yodzitetezera yovuta kwambiri, yopangidwa kuti izindikire ndikuchotsa zoopsa monga mavairasi, mabakiteriya, bowa, tizilombo toyambitsa matenda, komanso maselo a khansa. Pakati pa zinthu zambiri zomwe zimagwira ntchito limodzi—kuyambira pakhungu ngati chotchinga chakuthupi, mpaka maselo oyera amagazi, ma antibodies, ndi mamolekyulu olumikizirana—maselo a T… Werengani zambiri

Udindo wa RNA mu Kupanga Mapuloteni Kupanga mapuloteni ndi njira yofunika kwambiri yomwe imalola maselo amoyo kukula, kudzikonza okha, ndikuchita ntchito zosiyanasiyana zamoyo. Kumbuyo kwa njirayi, RNA (ribonucleic acid) imagwira ntchito yayikulu monga kulumikizana pakati pa chidziwitso cha majini chomwe chimasungidwa mu DNA ndi kupangidwa kwa mapuloteni mkati mwa selo. Popanda RNA, code ya majini singasinthidwe kukhala mamolekyulu… Werengani zambiri

Momwe Maantibayotiki Amagwirira Ntchito Popha Mabakiteriya Maantibayotiki ndi chimodzi mwa zinthu zofunika kwambiri zomwe zapezeka m'mbiri ya zamankhwala amakono. Mankhwalawa amagwiritsidwa ntchito pochiza matenda omwe amayamba chifukwa cha mabakiteriya, kaya amakhudza khungu, njira yopumira, njira ya mkodzo, kapena ziwalo zina. Ngakhale nthawi zambiri amatchedwa "germicide," maantibayotiki sagwira ntchito mofanana motsutsana ndi mabakiteriya onse, ndipo... Werengani zambiri

Chifukwa Chake Madzi Ndi Ofunika Pantchito ya Maselo Madzi nthawi zambiri amaonedwa ngati osafunika chifukwa amapezeka paliponse. Komabe, pamlingo wa zamoyo, madzi ndiye maziko enieni a moyo. Pafupifupi chilichonse chomwe chimachitika m'thupi—makamaka mkati mwa maselo—chimadalira madzi.
