Denuclearized tib neeg lub hlwb

Sawv daws yeej paub tias tus txiv neej yog ib tug eukaryote. Qhov no txhais tau tias tag nrho cov ntawm nws cov hlwb muaj organelles, uas yog tag nrho cov kev tshuaj ntsuam genetic ntaub ntawv - cov ntsiav. Txawm li cas los, muaj kev zam. Seb puas muaj nyob rau hauv tib neeg lub cev lub hlwb tsis muaj nuclei, thiab dab tsi yog tseem ceeb rau lub neej?

Denuclearized tib neeg lub hlwb

Lawv yuav tsis tau piv rau prokaryotes, muaj ib tug raug tus qauv. Yuav ua li cas hom ntawm uas tsis yog-nuclear hlwb? Ntsiav yog tsis nyob rau hauv cov ntshav - ntshav liab. Siv cov organelles lawv muaj ib tug complex set ntawm tshuaj, tso lawv los ua ib qho tseem ceeb functions. Platelets - platelets thiab lymphocytes - kuj tsis yog-nuclear hlwb. Ntsiav yog tsis nyob rau hauv lub hlwb, hu ua kav. Tag nrho cov ntawm cov lug combines lwm kos npe rau. Vim hais tias lawv tsis muaj cov tub ntxhais, lawv tsis muaj peev xwm rau cov me nyuam. Qhov no txhais tau tias tsis yog-nuclear hlwb, piv txwv uas tau muab, tom qab ua nws txoj kev ua yuav tuag thiab sawv daws yuav tshiab yog ua nyob rau hauv tshwj xeeb hauv nrog cev.

erythrocytes

Lawv txiav txim seb cov xim ntawm peb cov ntshav. Nuclear-free ntshav liab ntshav liab muaj ib qho txawv zoo - biconcave disk, uas zoo heev tsub kom lawv nto ntawm ib tug kuj loj me me. Tab sis lawv muaj pes tsawg yog ciav: nyob rau hauv lub 1 lub hlis twg. hli lawv cov ntshav yog mus txog rau 5 lab! Qhov nruab nrab cov ntshav liab ntawm tes nyob kom mus txog rau plaub lub hlis, tom qab uas lub hnub thiab neutralized nyob rau hauv tus po thiab lub siab. Tshiab hlwb yog tsim txhua txhua ob nyob rau hauv lub liab hlwb pob txha.

muaj nuj nqi ntawm erythrocytes

Li ntawd, es tsis txhob ntawm cov tub ntxhais hlwb muaj lub nuclear-free? Cov tshuaj no hu ua heme thiab globin. Tus thawj yog cov hlau-muaj. Nws yuav tsis tsuas tsuas cov ntshav liab xim, tab sis kuj ntaub ntawv ib tug tsis ruaj tsis khov compound nrog rau oxygen thiab carbon dioxide. Globin yog ib tug proteinaceous substance. Nyob rau hauv nws loj molecule shipped heme muaj them hlau ion. Nyob rau lub mechanism ntawm qhov kev txiav txim ntawm cov hlwb yuav muab piv rau lub tsheb tavxij. Lub ntsws yog txuas oxygen. Txij li thaum cov hlab ntsha nws kis rau tag nrho cov hlwb thiab tso muaj. Thaum oxygen kev koom tes tshwm sim organics oxidation txheej txheem los mus tso cov nyiaj ntawm lub zog uas ib tug neeg siv los mus siv cov kev ua. Lub npliag qhov chaw tam sim ntawd yuav siv sij hawm cov pa roj carbon dioxide, uas tsiv nyob rau hauv kev coj rov qab - mus rau lub ntsws, qhov chaw uas exhaled. Qhov no tus txheej txheem yog ib qho tseem ceeb rau lub neej. Yog hais tias tsis muaj oxygen yog txhab khoom mus rau lub hlwb, nws yog lawv gradual extinction. Qhov no yuav ua tau txaus ntshai rau lub neej ntawm tus kab mob raws li ib tug tag nrho.

Liab cov ntshav ua lwm tseem ceeb muaj nuj nqi. Nyob rau lawv daim nyias nyias protein marker yog hu ua v tau. Qhov no xam, raws li zoo raws li cov ntshav pab pawg neeg, yog ib qho tseem ceeb thaum lub sij hawm ntshav, cev xeeb tub, cov ntshav pub dawb thiab kev phais. Nws yuav tsum tau teem, raws li ib tug thiaj li hu ua Rhesus teeb meem yuav tshwm sim thaum incompatibility. Nws yog ib tug defensive cov tshuaj tiv thaiv, tab sis yuav ua tau kom tsis ntawm me nyuam hauv plab los yog kabmob.

Txom nyem noj haus, tsis tau phem, polluted cua yuav ua rau cov kev puas tsuaj ntawm cov ntshav liab. Thiaj li muaj ib tug loj heev kab mob uas yog hu ua ntshav liab los yog anemia. Nyob rau tib lub sij hawm tus neeg pom tau tias kiv taub hau, tsis muaj zog, txog siav, tinnitus. Pa tsis muaj peev xwm adversely muaj feem xyuam rau lub cev thiab kev puas hlwb kev ua si. Nws yog tshwj xeeb tshaj yog txaus ntshai thaum lub sij hawm cev xeeb tub. Yog hais tias txoj hlab ntaws mus rau lub fetus tau txais txaus cov pa, nws yuav ua tau kom loj teeb nyob rau hauv nws txoj kev loj hlob.

Tus qauv ntawm lub qe ua ntshav khov

Denuclearized hlwb platelets yog hu ua platelets. Thaum tsaug zog, lawv yeej muaj ib tug ca zoo li lub lens. Tiam sis thaum lawv swell vascular kev puas tsuaj, sib npaug tsim ib tug uas tsis yog-tas mus li protuberances ntawm tus txheej txheej - pseudopodia. Platelets yog ua nyob rau hauv lub hlwb pob txha thiab yog cov luv luv-nyob - txog li 10 hnub, neutralizing nyob rau hauv tus po.

Tus txheej txheem ntawm thrombus tsim

Matrix platelets muaj ib qho enzyme hu ua thromboplastin. Yog hais tias koj ua txhaum lub meej mom ntawm cov hlab ntsha nws yog ntshav. Nyob rau hauv nws cov cawv lub protein prothrombin ntshav mus rau hauv nws cov active daim ntawv no, nyob rau hauv lem, sawv fibrinogen. Raws li ib tug tshwm sim, qhov no tshuaj yuav insoluble. Nws dhau mus ua ib tug protein fibrin. Nws threads yog intertwined thiab tsim tau ib cov ntshav los khov rau ntawd. Tiv tshuaj tiv thaiv tiv thaiv kom txhob txhaws ntawm ntshav poob. Txawm li cas los, tus tsim ntawm ib tug ntshav los khov rau ntawd tsis pub dhau lub ntsha yog heev txaus ntshai. Qhov no tej zaum yuav ua rau nws cov kev sib tawg thiab tuag taus thiab ntawm tus kab mob. Kev ua txhaum ntawm lub txhaws txheej txheem uas hu hemophilia. Qhov no yog ib qho pub kab mob yus los ntawm ib tug tsis txaus tus naj npawb ntawm platelets thiab ua rau ntev li tsis ntawm cov ntshav.

qia hlwb

Cov hlwb yog hu ua kav nuclear-free yog tsis nyob rau hauv vain. Lawv yeej yog lub hauv paus rau tag nrho cov lwm leej lwm tus. Lawv kuj hu ua "txhob ntshiab". Qia hlwb yog pom nyob rau hauv tag nrho cov ntaub so ntswg thiab kabmob, tiam sis feem ntau ntawm lawv muaj cov hlwb pob txha. Lawv pab mus rau restore lub sam xeeb txog qhov twg nws yuav tsum tau. Qia tig mus rau hauv lwm yam cell hom nyob rau hauv lawv cov kev puas tsuaj. Nws yuav zoo li hais tias yog muaj xws li ib tug tej yam yees siv mechanism txiv neej yuav tsum nyob mus ib txhis. Yog vim li cas yog no tsis tshwm sim? Qhov no yog hais tias nrog lub hnub nyoog, kev siv ntawm cov ntau yam ntawm qia hlwb yog zoo heev txo. Lawv yog cov twb tsis tau yaj puas cov ntaub so ntswg. Tab sis muaj lwm txaus ntshai. Muaj yog ib tug zoo yuav uas rau cov qia hlwb nyob rau hauv mob cancer, uas yuav inevitably ua rau tus tuag ntawm tej sia.

Tsis-nuclear hlwb: piv txwv thiab nta txim hluav taws xob

Qhov xwm ntawm tus uas tsis yog-nuclear hlwb yog haum ntau. Piv txwv li, prokaryotic yog xiav-ntsuab algae thiab cov kab mob. Tab sis, nyob rau hauv sib piv rau cov uas tsis yog-nuclear tib neeg lub hlwb, lawv tsis tuag tom qab lawv tuaj ua lawv lom lub luag hauj lwm. Qhov tseeb hais tias prokaryotes muaj kev tshuaj ntsuam genetic khoom. Lawv yog li ntawd tau faib uas tshwm sim los ntawm mitosis. Raws li ib tug tshwm sim, tsim ob genetic ntawv luam ntawm cov niam txiv ntawm tes. Mob muaj keeb ntaub ntawv sawv cev prokaryotes annular DNA molecule uas doubles ua ntej division. Qhov no tseem analogue yog hu ua nucleoid. Nyob rau hauv uas tsis yog-nuclear nroj tsuag yog cov nyob hlwb ntawm vascular cov ntaub so ntswg - sab cib hlab.

Yog li, qhov uas tsis yog-nuclear tib neeg lub hlwb yog tsis tau faib, yog li ntawd lawv nyob ua ib ke ib luv luv lub sij hawm ntawm lub sij hawm mus ua nws zog. Tom qab ntawd los lawv puas tsuaj thiab intracellular digestion. Lawv tsim ntsiab (ntshav liab), platelets (platelets) thiab qia hlwb.
