Muaj tsib sib txawv leukocytes uas ua kom tiav cov haujlwm tshwj xeeb raws li lawv lub peev xwm thiab cov hom ntawm invaders lawv sib ntaus sib tua. Lawv hu ua neutrophils, basophils, eosinophils, monocytes, thiab lymphocytes. Cia peb tshawb xyuas txhua yam ntawm no kom ntxaws.
Ua kom pom qhov no, 4 hom leukocytes yog dab tsi?
Hom ntawm WBCs . Hom sib txawv ntawm cov qe ntshav dawb (leukocytes) suav nrog neutrophils , cov basophils , eosinophils , cov lymphocytes , monocytes cov , thiab macrophages.
Qhov thib ob, leukocytes yog dab tsi? Leukocytes yog ib feem ntawm lub cev tiv thaiv kab mob. Lawv pab lub cev tiv thaiv kab mob thiab lwm yam kab mob. Hom ntawm cov leukocytes yog granulocytes (neutrophils, eosinophils, thiab basophils), monocytes, thiab lymphocytes (T cells thiab B cells). Kuj hu ua WBC thiab qe ntshav dawb.
Tsis tas li ntawd, 2 hom leukocytes yog dab tsi?
Ob Hom Yooj Yim ntawm Leukocytes Cov phagocytes yog cov hlwb uas zom zom cov kab mob thiab cov cov lymphocytes yog cov hlwb uas tso cai rau lub cev nco qab thiab paub txog cov neeg ua phem dhau los. Cov qe ntshav dawb pib hauv cov pob txha ua cov qia hlwb.
Koj nco ntsoov hom leukocytes li cas?
Txhawm rau nco ntsoov ntau hom leukocytes hauv lawv qhov kev faib ua feem hauv cov ntshav, siv cov mnemonic no:
- Tsis txhob (neutrophils): 60%
- Cia (lymphocytes): 30%
- Liab (monocytes): 6%
- Noj (eosinophils): 3%
- Txiv tsawb (basophils): 1%.

Lub hom phiaj ntawm cov roj raus dej uas siv nrog 100x lub hom phiaj xeem ntawv yog dab tsi?
Hauv lub tshuab tsom me me, kev tso roj yog txheej txheem siv txhawm rau txhawm rau daws qhov teeb meem ntawm lub tsom iav. Qhov no yog ua tiav los ntawm kev raus ob lub hom phiaj tsom iav thiab cov hnoos qeev hauv cov roj pob tshab ntawm qhov ntsuas siab refractive, yog li ua kom cov zauv zauv ntawm lub hom phiaj tsom iav
Dab tsi yog OSHA Nws lub hom phiaj yog dab tsi?
OSHA Lub Hom Phiaj Nrog Txoj Cai Kev Nyab Xeeb Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv xyoo 1970, Congress tau tsim Txoj Haujlwm Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA) txhawm rau kom muaj kev nyab xeeb thiab noj qab haus huv ua haujlwm rau cov txiv neej thiab poj niam ua haujlwm los ntawm kev teeb tsa thiab ua raws cov qauv thiab los ntawm kev qhia, nthuav tawm, kev kawm thiab kev pab
Dab tsi yog hom cytokines txhais hom & Muaj nuj nqi?
Cytokines yog ib pawg ntawm cov protein uas zais los ntawm cov cell ntawm lub cev tiv thaiv kab mob uas ua cov tshuaj xa xov. Cytokines tso tawm los ntawm ib lub cell cuam tshuam rau kev ua ntawm lwm lub cell los ntawm kev khi rau cov neeg txais khoom ntawm lawv qhov chaw. Los ntawm cov txheej txheem no, cytokines pab tswj kev tiv thaiv kab mob
Dab tsi yog 3 hom hlwb pob txha thiab lawv lub luag haujlwm yog dab tsi?
Cov pob txha tau tsim los ntawm peb hom cell hom: Osteoblasts, Osteocytes thiab Osteoclasts. Osteoblasts: Osteoblasts yog cov pob txha tsim cov hlwb uas nqis los ntawm cov hlwb osteoprogenitor. Osteocytes: Osteoclasts:
Dab tsi yog hom sib txawv ntawm leukocytes thiab lawv lub luag haujlwm li cas?
Hom qe ntshav dawb Monocytes. Lawv muaj lub neej nyob ntev dua li ntau cov qe ntshav dawb thiab pab ua kom cov kab mob puas tsuaj. Lymphocytes. Lawv tsim cov tshuaj tiv thaiv kab mob los tawm tsam cov kab mob, kab mob, thiab lwm yam ua rau muaj kev phom sij. Neutrophils. Lawv tua thiab zom cov kab mob thiab cov hu ua fungi. Basophils. Eosinophils
