Ntchito madzi mchipindamo. Chiwerengero cha H2O zili mu thupi

Madzi - mankhwala apadera. Iwo kufalikira ponseponse padziko lathuli. Taganizirani kodi kukhala ndi moyo popanda H2O molekyulu? Inde, ndipo zikuimira kanthu - moyo padziko lathuli kuti kulibe. mwamuna ndi 70% madzi. Wamng'ono thupi, m'pamenenso zolembedwamo, koma msinkhu, nambala iyi amachepetsa. Mwachitsanzo, kutenga mwana wosabadwayo - kuchuluka zili m'menemo ndi 90% H2O.

M'nkhaniyi, ife amati inu kusankha zonse ntchito za madzi mu chipinda ndipo tione chilichonse. Nkofunika amatchula kuti iye anapeza m'njira ziwiri: ufulu nam'manga. Ife amakumana lino.

madzi

Aliyense akudziwa kuti madzi kumathandiza kwambiri, koma mbali yofunika pa moyo wathu. Popanda, dzikoli likanakhala wakufa, zopanda moyo chipululu. Asayansi lero akuphunzira madzi ndi ntchito ka thupi la munthu.

Takambirana kale za chakuti madzi chopezeka maselo mu mawonekedwe ufulu ndi kuchuluka. Woyamba akutumikira kufalitsa zinthu - kusamutsa iwo mu chipinda ndipo mwa izo. Ndiyeno iwowa anati:

• pakati ulusi;
• nembanemba;
• zedi;
• nyumba yotere.

Ndipo madzi ufulu ndi omangidwa mu selo chofunika kuchita ena ntchito, zomwe akambirana nthawi ina. Ndipo tsopano - mawu ochepa za momwe iye anakonza H2O molekyulu.

molekyulu

Choyamba, ife potanthauza chilinganizo maselo madzi: H2O. Ichi ndi chinthu wamba kwambiri pa dziko, ndipo muyenera kukumbukira izo, chifukwa chilinganizo maselo madzi sizachilendo m'madera osiyanasiyana a ukatswiri. Izo, poyamba, zopezeka mu matupi anthu onse ngakhale dzino enamel ndi fupa Komabe, kumene kuli oche- - 10% 20%, motero.

Monga tanena kale, kuposa thupi wamng'ono, madzi mmenemo panonso. Asayansi amanena kuti ife msinkhu chifukwa chakuti mapuloteni simungakhoze kuwamanga wambirimbiri madzi. Koma izi Komabe, okha kungoganizira.

ntchito

Tsopano kusankha ntchito za madzi muchipindachi, zambiri za iwo mopitirira bwino pa mndandanda zotsatirazi:

• H2O akhoza kuchita monga zosungunulira, monga pafupifupi onse mankhwala zochita - ion - ndipo zimachitika madzi. Tikumbukenso kuti pali hydrophilic mankhwala (zomwe kupasuka, mwachitsanzo mowa ndi, shuga, amino zidulo ndi zina zotero), koma palinso hydrophobic (mafuta zidulo, mapadi ndi ena).
• Madzi akhoza kuchita ngati wothandizira.
• Achiritsa zoyendera kulamulira kutentha nchito kandalama.

Tikupereka aliyense wa iwo ankaona payokha. Tiyeni tipite kuti, poyamba pa mndandanda - ndi ntchito ya zosungunulira lapansi.

zosungunulira

ntchito madzi mu selo achuluka, koma mmodzi wa chopambana - ndi kuthandiza mu njira ya kuchuluka kwa zochita. H2O molekyulu akhoza kuchita monga zosungunulira a. Pafupifupi onse zochita mu khungu - ndi ion, mwachitsanzo, malo omwe iwo akhoza kutenga malo - ndi madzi.

reagent

Ntchito zotsatirazi madzi selo - ndi mbali mu mankhwala rekatsiyah zikuchitika m'thupi reagent a. Njirazi ndi monga:

• hydrolysis;
• polymerization;
• photosynthesis, ndi zina zotero.

Tsopano pang'ono za zimene wothandizira. Mu umagwirira, zotchedwa mankhwala kuchita zinthu zosiyanasiyana mankhwala. Chinthu chofunika kwambiri - ichi ndi chimene chiri ngakhale nawo zotani, koma chinthu chithandizo mu nkhani iyi si. The reagents zasayansi (mu osiyanasiyana koma iwo amatchedwa reagents) - ndi zachilendo.

Madzi monga reactant ndi okhudzidwa pokonza zinthu zina amafunika thupi.

ntchito zoyendera

Kodi n'chifukwa chiyani timakhala? Thupi lathu chinakhalapo chifukwa chokha chakuti maselo a moyo, umene analemba. Ndipo iwo ayenera yamikani dongosolo yake yapadera ndi ena mwa maonekedwe a H2O molekyulu. Tanena kale kuti madzi - ndi mbali yofunika ya thupi lathu, ndi iri yonse yochepetsetsa lili mamolekyulu izi mwapadera, makamaka, mu malo oyamba mu kapangidwe kake.

Timanyamula wa madzi mu ntchito selo - ndi cholinga china cha H2O mu thupi lathu. Madzi ali mbali - kuzindikira danga extracellular, chifukwa zakudya ndi kulowa mu selo.

Wina ndi kudziwa kuti magazi ndi lymph mulinso madzi, ndi wopanda kumabweretsa zina zotsatira: kukha magazi kapena thrombosis.

thermotaxis

Kodi ntchito ya madzi muchipindachi, sitinalandire zosankhidwa kunja? Kumene, thermoregulation. Timanena kuti madzi amatha kuyamwa kutentha ndi kusunga kwa nthawi yaitali. Choncho, H2O kungathandize foni kuchokera kutenthedwa kapena undercooling. Ntchito thermoregulatory chofunika osati maselo wosakwatiwa, komanso lake lonse.

kapangidwe ntchito

Kodi ntchito ya madzi muchipindachi, ife kale adazifuna, mpaka tione koma cholinga china - ndi kukonza dongosolo selo.

Kodi munayesapo Finyani madzi? Ngakhale zasayansi kukwaniritsa zimenezi ndi kovuta. Mundawu wa madzi n'kofunika kuti tikhalebe ndi mawonekedwe ndi kapangidwe ka mukachipinda.

Kwamuyaya: chamoyo popanda madzi. Timamva ludzu pamene thupi limataya za 3% madzi, ndi imfa ya 20%, maselo amafa ndipo, chotero, anthu. Muziona mmene madzi akumwa.
