Ho utloisisa maro a sa fetoheng le a matla
Fisiks, mokelikeli o hlalosoa e le ntho e ka phallang. U ithutile hore lintho tseo re kopanang le tsona bophelong ba letsatsi le letsatsi li na le lintho tse tiileng, tse metsi le likhase. Lentsoe mokelikeli le akaretsa lintho tse metsi le likhase, hobane lintho tse metsi tse kang metsi le likhase tse kang moea li ka phalla. Lintho tse tiileng tse kang lefika kapa tšepe li ke ke tsa phalla 'me ka hona li ke ke tsa aroloa e le lintho tse metsi. Ho utloisisa tlhaloso ena hamolemo, ho molemo ho nahana ka mehlala e meng ea bophelo ba letsatsi le letsatsi. Ha u hlapa, ka sebele u hloka metsi. Ho fihla letamong, metsi a phalla ho tsoa selibeng kapa a huloa selibeng. Metsi ke mohlala o mong oa mokelikeli. Ho na le mehlala e meng ea lintho tse metsi, joalo ka oli e tlotsang, lebese, jj. Lintho tsena kaofela tse metsi li ka aroloa e le lintho tse metsi hobane li ka phalla ho tloha sebakeng se seng ho ea ho se seng. Likhase le tsona ke lintho tse metsi. Likhase li ka boela tsa phalla ho tloha sebakeng se seng ho ea ho se seng. Moea o fokang ke mohlala oa moea o tsamaeang ho tloha sebakeng se seng ho ea ho se seng.
Ntle le lintho tse tiileng, tse metsi le likhase, ho na le mofuta o mong oa taba e bitsoang plasma. Plasma ke khase e nang le ioni 'me hangata e bitsoa boemo ba bone ba taba . U ka ithuta ho eketsehileng ka plasma kolecheng. Leha ho le joalo, plasma ha e aroloe e le mokelikeli.
Metsi a sa Fetoheng le a Matla
Metsi ke karolo ea bohlokoa bophelong ba rona ba letsatsi le letsatsi. Letsatsi le leng le le leng, rea a hema, rea a noa, esita le ho phaphamala kapa ho teba ho 'ona. Letsatsi le leng le le leng, lifofane lia fofa ho 'ona, likepe lia phaphamala ho 'ona, 'me likepe tse tsamaeang ka tlas'a metsi li ka phaphamala kapa tsa hoholeha ho 'ona. Metsi ao re a noang le moea oo re o hemang le tsona li potoloha ka hare ho 'mele ea rona kamehla, ka linako tse ling re sa hlokomele.
Ha re ithuta maro, re a arola likarolo tse peli: di-static tsa mokelikeli (metsi a phomotseng) le di-dynamic tsa mokelikeli (metsi a tsamayang). Ho di-static tsa mokelikeli, re hlahloba maro a phomotseng boemong ba tekano. Ka hona, re hlahloba maro a phomotseng. Ho di-dynamic tsa mokelikeli, re hlahloba maro a tsamayang.
