Njengomuntu kuyinto: isakhiwo bangaphandle zangaphakathi namalungu omzimba womuntu

owenza umuntu kanjani? Ezinganeni ukuphendula lo mbuzo ngakho ayilula kangako. Futhi njengoba ufuna ukuqonda lo mshini eziyinkimbinkimbi - nakakhulu. Kodwa zonke emzimbeni womuntu kungaphansi kwemithetho ethile.

Umzimba kudivayisi

kanjani emzimbeni indoda? Man kuyinto amaningi. Ngokuya taxonomy imelele uhlobo Chordates. Ngesikhathi komqondo nezinga lokukhula kwengane embryonic ngesikhathi notochord ubumbe, kwemizwa tube futhi gill izimbotshana ku pharynx. Ukuthuthukisa, basuke uguqulwe ube skeleton, emgogodleni ubuchopho, futhi izitho zokuphefumula kukhona emaphashini. Njengazo zonke izinhlobo zezilwane ezincelisayo, umhlengikazi oyedwa izingane zabo ubisi, a Milky, umjuluko nezindlala sebaceous, zonke iziboya emzimbeni bese Horny isikhumba kumiswa.

Njengomuntu kuyinto? Isidumbu sakhe akhiwa amangqamuzana, okuyinto ehlangana nezicubu. Isiqalo nesigcino yokugcina, yena, yakha izinhlaka. Nokho, ngamunye wabo eceleni ayikwazi ukwenza imisebenzi isimiso esiyinkimbinkimbi sokuphila izinqubo. Ngakho-ke, iziphathimandla bamunye izinhlelo bokuphila futhi zisebenza kahle.

Ikakhulukazi isilwane amaseli

omzimba womuntu akheke ejwayelekile kwezilwane. Ziyakwazi eukaryotic, ngoba ane-nucleus. Lokhu cell isakhiwo njalo liqukethe ukwaziswa kwezakhi zofuzo eziqukethwe molecule e-DNA. Ngu uhlobo lokudla umuntu heterotrophs. Ngenxa yalesi sizathu, amaseli ayo siziswele oluhlaza chloroplast plastids lapho photosynthesis kwenzeka. I organelles ezinkulu kukhona mitochondria lysosomes, Golgi apharathasi, reticulum endoplasmic, cytoskeleton futhi centrioles.

Njengomuntu kuyinto: izinhlobo eziyisisekelo kwezicubu zomzimba

amaqembu amaseli banezimfanelo ubunye lokuphatselene nesakhiwo nemsebenti abizwa ngokuthi kwezicubu. Kubantu, kukhona izinhlobo ezine izicubu:

1. EPITHELIAL - siqukethe amaseli encane, ezinabantu ohlanganisa. It yakha nesembozo umzimba kanye izitho zangaphakathi, kuba uhlobo olukhethekile yensimbi ezisekelwe. Iqukethe cishe akukho izidakamizwa intercellular. izicubu EPITHELIAL usebenze umsebenzi Ukuvikelwa kanye exchange of izinto nge imvelo.

2. Uxhumano - kuyisisekelo ukuthi yakha kwezitho zomzimba. Siqukethe amaseli ezinkulu, okuyinto ahlelwe inombolo enkulu lomcebo intercellular. izinhlobo zayo siyithambo, uqwanga, amafutha, legazi.

3. Muscle - siqukethe imicu uyakwazi ukusikwa. It wenza umsebenzi ukunyakaza kwezitho ngabanye futhi umzimba wonke emkhathini.

4. Nervous - izinzwa wakhiwa izinqubo eziningi adlulisa ezahlukene zolwazi, ukuhlinzeka ubuhlobo umzimba njalo nezwe elingaphandle.

kwezitho zomzimba kanye nezinhlelo: izici inhlangano

isitho ngasinye yakhiwa izinhlobo eziningana izicubu. Ngokwesibonelo, izicubu senhliziyo esilimele kwakhiwa, sizungezwe zezinzwa izicubu emgodleni. Kodwa isitho ngobukhulu ubhekwa isikhumba. Ngemva endaweni ingqikithi 2 square metres. Kungani isikhumba - iyona umzimba? Ngenxa yakhiwa kwezicubu eziningana: EPITHELIAL futhi zezinzwa.

Ukuze uqonde ukuthi umuntu akuyona, kufanele ujwayelene nomqondo isitho izinhlelo. Izibonelo izakhiwo ezinjalo zaziwa: wokugaya ukudla, kwegazi ... Ngayinye yalezi iqoqo izitho, ukusebenza ahlangene we umsebenzi owodwa. Cabanga isakhiwo idatha zomzimba womuntu ngokuningiliziwe.

uhlelo zemisipha

Lolu hlelo ngokuhamba anatomy elalinikezelwe esifundweni sokuqala kakhulu. enza umzimba womuntu kanjani? Okokuqala, lolu hlaka lwamathambo kuyinto enkabeni yalo. Yena imelelwa neminye iminyango eminingana. Kuyinto lwamathambo ekhanda, esifubeni, nendawo ezizobekwa khulula wemikhawulo yasenhla nemithombo yasenzansi. Ngokungafani nezinye izilwane, ukuze abantu bathambekele bipedalism. Linikeza ikghono imisipha ukuthi Banamathele bone nemisipha.

Zokuphefumula futhi isimiso sokujikeleza kwegazi

Siyaqhubeka cabangela indlela umzimba womuntu. ukhona awunakuba khona ngaphandle kokuthethelela negesi lokushintshisana. Lesi sici sihlinzeka izinhlelo ezimbili ngesikhathi esisodwa. Zokuphefumula ethulwa izindlela womoya kanye namaphaphu. Lapho ukuhogela umoya ungena therein umoya-mpilo. Kule bubble igesi yamaphaphu engena kulencane izitsha, ama-capillary. Nge wamanje igazi elingenawo umoya enikeziwe kuseli ngayinye i umzimba. Le nhlangano yenkolo yokulwela Kwenzeka okuphambene nalokho-carbon dioxide, okuyilona elisebenzayo futhi ukudlula emaphashini esuswa umzimba.

Uhlelo isimiso sokujikeleza kwegazi emelelwa inhliziyo negazi izitsha ezine-chambered: imithambo, ama-capillary kanye emithanjeni. Thayipha lesi simiso umuntu ivaliwe, ngoba igazi emzimbeni wakhe ingaphakathi akusho hlanganise uketshezi futhi ujikeleza ngaphakathi ezitsheni.

I wokugaya ukudla bese uhlelo excretory

Izinto ezenziwa abantu akunakwenzeka ngaphandle exchange of izinto nge imvelo. Irisidi, eqhekeza futhi nokwenziwa kwezakhi eyalo wokugaya ukudla. kanjani umzimba womuntu, futhi ikakhulukazi, kule sethi izitho? It imelelwa temlomo, pharynx, emphinjeni, esiswini, amathumbu amancane ikholoni, okuyinto ukuvula ingquza. Kungenxa ngokusebenzisa wokugaya ukudla uhlelo hlobo. Kodwa ukuqaliswa imisebenzi yayo ngeke kwenzeke ngaphandle nezindlala ekhethekile ama-enzyme ukuthi sokudiliza kuyindaba enzima eziphilayo zibe elula. Lezi zinto zihlanganisa salivary nezindlala, amanyikwe kanye isibindi.

Urinary emelelwa emabhontjisi abhanqiwe izinso, ureters, isinye, nibonakala isiteshi ukuvula. Ngosizo lwawo umzimba ukuqeda amanzi angadingeki nosawoti, metabolites anobuthi.

Izici isakhiwo kwesimiso sokuzala

Cabanga indlela yomuntu yenziwa ngokuya umsebenzi zokuzala. Kuyinto umzimba dioecious nge kokukhulelwa yangaphakathi. uhlobo ukuthuthukiswa - umugqa oqondile. Futhi labesifazane uhlelo amadoda zokuzala imelelwa nezindlala, Amapayipi kanye amaseli. Noma kunjalo, kukhona ukungezwani okukhulu. In amadoda, kuba testes, Amapayipi yabo futhi gametes ezincane mobile - isidoda. La mangqamuzana zihlale asebenzayo futhi labo abazokwazi kokukhulelwa.

Female uhlelo zokuzala siqukethe amaqanda abhanqiwe, oviducts bese fixed, gametes elikhulu. Ukuvundisa badinga ukuhambisa kusukela gonads ku tube fallopian. Le nqubo ithatha indawo kuphela ngezikhathi ezithile nomjikelezo wokuya esikhathini, okuthiwa yi-ovulation. Ngezinye confluence gametes kwakhiwa zygote. It ihlukaniswe futhi kancane kancane bakha isakhiwo multi-cell, okwathi ngokuhamba kwesikhathi uguqulwe ube yingane. Intrauterine kwengane esiswini inikeza isivikelo umzimba ezincane ngesikhathi sokukhulelwa kanye nokusebenza ezinyangeni zokuqala zokuphila.

Izici kohlelo womuntu sezinzwa

indoda kuphela uyisidalwa biosocial. Lokhu ngokuyinhloko kufezwa ngokusebenzisa ezingeni lelisetulu ukuthuthukiswa isimiso sezinzwa. It siqukethe le asebuchosheni nomgogodla, kanye imicu yezinzwa ukuthi ukhulise kusukela kubo. Man ozalwa ezithile ikhaliphe unconditioned kanye nemizwelo kwezilwane. Nokho, ngesikhathi ukuphila ifomu yakhe futhi impendulo kuluthola. Kanjani ubuchopho bomuntu? Kunzima kakhulu, uma kuqhathaniswa nezinye chordates. It ukuhlukanisa phakathi cortex cerebral futhi inani elikhulu convolutions, okuyinto ukwandisa endaweni yayo. isici kuphela abantu yokukhuluma okunenjongo kanye nekhono lokuhlaziya. Uhlala umphakathi futhi ngezinga elithile kungaphansi kwemithetho nomphakathi.

isiqondiso imisebenzi

Ngokwemvelo, kwakha isimiso esiyinkimbinkimbi enjalo idinga isiqondiso imisebenzi. Lokhu kwenzeka ngezindlela ezimbili kanyekanye. Ngosizo isimiso sezinzwa zomzimba womuntu ithola ulwazi mayelana izinguquko ezihlukahlukene ezimweni imvelo futhi ngokuphazima kweso ayiphendule. Ngezindlela eziningi lokhu kufezeke inzwa izinhlelo. abantu zabo ezinhlanu. Lokhu emehlweni, touch, ukuhogela, ukuzwa kanye nekhono lokuqonda iphunga. Ezinye izazi ziye zathi waveza esinye, okuthiwa "sixth sense" noma umuzwa. Nokho, futhi isakhiwo noma indlela zalesi simiso ukuthola nokuchaza kodwa asikho esiye saphumelela. A ductless ndlala likhiphele igazi izinto ezikhethekile - hormone lokulawula izinqubo wekukhula, intfutfuko kanye homeostasis. Lo mqondo kusho ukugcinwa kwamakhilomitha njalo imvelo yangaphakathi.

Yileyo indlela umzimba womuntu. Kuyinto isimiso esiyinkimbinkimbi njalo kuletha ndawonye amaseli, izicubu, kwezitho izinhlelo. Ngayinye yalezi izakhiwo has ngezinga eliphezulu of lunye futhi esihlelwe esebenzisa kwemizwa kanye humoral isiqondiso izinhlelo.
