Kunezve zvakawanda zvakavanzika pamusoro pehuropi hwemunhu, asi vatsvakurudzi vakazarura huwandu hwechokwadi hunofadza pamusoro pokuti hunoshanda sei. Heano mapfumbamwe echokwadi nokukurumidza kuti uite pamugwagwa unonzwisisa zviri nani zveuropi.
1 - Inorema kudarika iwe unogona kufunga
Ivhareji yehutano hwehutano hwemunhu hunorema anenge anenge 3 pounds uye inowedzera kuva yakakura mumurume kupfuura vakadzi. Ndiyo imwe yemimwe miviri yedu yakakura uye yakakora kwazvo.
2 - Ndiyo Mvura zhinji
Uropi hwemunhu hunoumbwa inenge 75 muzana yemvura, uyewo mafuta uye mapuroteni.
3 - Inokura zvakanyanya Kubvira paucheche kusvika kuhukuru
Ivhareji yekuberekwa kwechechecheche yehutano hwemwana inenge inenge 350 kusvika ku 400 gm, kana kuti katatu yemapirundi. Izvozvo zvinoreva kuti inokura kusvika kanane hukuru hwepakutanga kubva paucheche kusvika pakuva munhu mukuru.
4 - Yakagadzirwa Mamiriyoni eNeurons
Zvakaitika munguva pfupi yapfuura zvinoratidza kuti chiyero chehutano hwevanhu vakuru hune mamiriyoni masere mabhiriyoni emasero, anonzi neurons. Neurons ndiyo nhume muhutano hwedu, kutakura ruzivo uye kutaurirana nhengo dzedu dzemuviri, misungo yedu, uye mumwe nomumwe.
5 - Yakaitwawo Nemabhiriyoni eGlial Cells
Kutsvakurudzwa kwemazuva ano kwakaratidza kuti rutendo rwekuti kune 10 glial cells pane imwe neimwe neuron inhema. Chiyero chiri pedyo ne1: 1. Masvikiro emasero anosvika anenge hafu yeuropi nemutsipa wepelinha, kunyange chiyero ichi chinogona kusiyana kubva pane imwe nzvimbo kuenda kune imwe inotevera.
Glial cells anoita mabasa akawanda, kusanganisira kuita seglue kubata neuroni pamwe chete. Vanoitawo basa rekuchengetedza imba nekuchenesa vanodarika neurotransmitter uye vanotsigira synaptic kukura.
Kune marudzi akawanda akasiyana-siyana emagetsi e-glial: astrocytes, oligodendrocytes, microglia, ependymal masero, radial glial, satellite cells, uye schwann masero.
6 - Inogona Kuumba Masero Matsva, Kunyange Muhukuru
Uropi hunoenderera kuumba hutsva huri pakati peeurons muhupenyu hwedu hwose. Zvitendero zvekare zvakaratidza kuti uropi hwakarongedzwa mumatombo pakutanga kweupenyu, asi nyanzvi dzesayenzi zvino dzinoziva kuti uropi hahuri kutombomira kuchinja.
7 - Inoda Zvose Simba reKushanda
Kunyange zvazvo inomiririra inenge 2 muzana yemutengo wose wemuviri, uropi hunoda 20 peresenti ye oksijeni yemuviri uye 25 muzana yeglucose yemuviri.
8 - Kuwirwadziwa kweBrain Kukuvara Ndiko Kunotyisa
Pakati pevana nevakuru pakati pezera remakore 1 ne44, kukuvara kwehupfungwa kunokonzera ndicho chinokonzera chirema nekufa. Zvikonzero zvinowanzokonzerwa nekukuvara kwehuputi uku kunosanganisira kuwira, motokari kuputika, uye kurwisa.
9 - Ubongo Hwedu Hwakave Hwakanga Uchiita Kuduku
Uwandu hweusero hwehuropi hwemunhu hwakaderera ne-9 masentimita masendimita kupfuura makore mashanu apfuura. Izvi zvinogona kunge zvakakonzerwa nekuti miviri yedu yakawanawo zvishoma kudarika nguva.
