Hauv qab cov Microscope : Ntshav . Nyob rau hauv tag nrho, koj cov qe ntshav liab tuav txog 2.5 grams hlau. Cov qe ntshav liab yog zoo li tus zoo nyiam donuts uas tsis heev tau txais lawv lub qhov tsim. Lawv yog biconcave discs, ib qho zoo li uas tso cai rau lawv nyem los ntawm me me capillaries.
Ib yam li ntawd, nws tau nug tias, cov qe ntshav liab zoo li cas nyob rau hauv lub tshuab tsom iav?
Lawv tshwm raws li biconcave discs ntawm cov duab zoo ib yam thiab qhov loj me (7.2 microns) uas tsis muaj cov organelles thiab granules. Cov qe ntshav liab muaj cov tsos liab liab vim lawv cov ntsiab lus siab ntawm hemoglobin. Lub hauv paus daj ntawm txhua qhov ntshav liab yog vim lub concavity ntawm lub disc.
Ib sab saum toj no, qhov loj npaum li cas koj xav pom cov qe ntshav liab? 2 Teb. Nyob ntawm seb ntau npaum li cas koj xav pom, 400 X li (raws li Chris tawm tswv yim) yog tiag tiag txaus. Nco ntsoov, lub lens (es) hauv qab/dhau theem tau sau daim ntawv lo 10 X , 20 X, 40 X , thiab lwm yam, thaum lub qhov muag feem ntau 10 X lossis tej zaum 20X (muab ob npaug ua ke muab qhov kawg loj).
Tsis tas li kom paub, cov qe ntshav dawb zoo li cas hauv lub tsom iav?
Lawv tshwm xim liab thiab muaj zog dua li liab hlwb (koj tuaj yeem pom qee cov platelets hauv cov duab 5 thiab 6). Tsis zoo li liab hlwb , cov leukocytes muaj nucleus. Nws pom tau yooj yim hauv qab cov tsom iav , tab sis tsuas yog tom qab tau pleev xim pleev. Leukocytes tau muab faib ua granulocytes thiab lymphoid hlwb.
Crenated txhais li cas?
kev tsim kho . npe. Ib tug rounded projection, raws li nyob rau hauv cov npoo ntawm lub plhaub. Qhov xwm txheej los yog lub xeev ntawm kev ua tsim . Cov txheej txheem ua los ntawm osmosis nyob rau hauv uas cov qe ntshav liab, nyob rau hauv cov tshuaj hypertonic, undergo shrinkage thiab tau txais ib tug notched los yog scalloped nto.

Dab tsi yog tsom iav tsom iav?
Kev tsom me me tshwj xeeb yog cov txheej txheem kev yees duab uas tsis nthuav dav uas tso cai rau koj kom pom kev thiab txheeb xyuas lub qhov muag qhov muag. Siv lub computer-pab morphometry, niaj hnub specular tsom tsom xam qhov loj me, cov duab thiab cov pejxeem ntawm cov endothelial cells
Kuv puas tuaj yeem muab kuv cov iav tsom iav los ua tsom iav?
Yog, koj tuaj yeem ua tau. Koj cov tsom iav RX ib txwm tuaj yeem pleev xim rau ib qho xim uas koj xav tau thiab ua rau koj ib khub tsom iav tsom iav. Tsuas yog coj koj lub tsom iav mus rau lub khw muag khoom kho qhov muag hauv cheeb tsam thiab ua rau koj cov iav tsom iav. Nws yog qhov ua tau rau koj kom koj cov iav tsom iav tsis tu ncua
Vim li cas qhov sib txawv hauv qhov tsom iav tsom iav tseem ceeb heev?
Qhov sib piv: Lub tshuab tsom me me yog ua kom lub ntiaj teb me me pom rau tib neeg qhov muag. Txhawm rau ua qhov no kom tiav, tib neeg lub qhov muag yuav tsum muaj peev xwm pom qhov txawv ntawm ib qho piv txwv los ntawm nws ib puag ncig. Qhov sib piv zoo dua, nws yooj yim dua yog pom qhov sib txawv hauv cov duab
Koj puas tuaj yeem pom cov qe ntshav dawb hauv qab lub tsom iav?
Muab hais tias tag nrho cov qe ntshav dawb muaj ntau dua 5 micrometers hauv txoj kab uas hla, lawv loj txaus kom pom tau siv lub tshuab tsom tsom pom zoo ib yam (tsom iav tsom). Staining nrog Leishman's stain ua rau nws ua tau tsis tsuas yog yooj yim txheeb xyuas ntau hom leukocytes, tab sis kuj suav lawv
Vim li cas lub tshuab tsom iav hu ua lub tshuab tsom me me?
COMPOUND MICROSCOPES thiaj li raug hu vim tias lawv tau tsim nrog cov kab ke sib xyaw ua ke. Lub hom phiaj lo ntsiab muag muab thawj qhov kev nthuav dav uas yog compounded (multiplied) los ntawm ocular lens (qhov muag)
