Muaj ob hom alveolar hlwb: hom I (hom prevailing) thiab hom II alveolar hlwb. Hom I alveolar cells yog squamous tsis tshua muaj hlwb uas cuam tshuam rau hauv cov txheej txheem ntawm cov pa pauv ntawm cov alveoli thiab ntshav. Hom II alveolar hlwb koom nrog hauv kev tso tawm ntawm cov proteins surfactant.
3 hom alveolar hlwb yog dab tsi?
Txhua lub alveolus muaj peb hom ntawm tes:
- Type 1 pneumocytes.
- Type 2 pneumocytes.
- Alveolar macrophages.
Puas yog Hom 1 alveolar cells yooj yim squamous?
Alveolar Epithelial Cells
Feem ntau ntawm cov alveolar saum npoo yog npog los ntawm cov cell squamous yooj yim hu ua hom I pneumocytes (Daim duab 1-9). Cov hlwb no muaj cov nucleus me me nrog cov txheej txheem cytoplasmic heev uas npog 4000 txog 5000 µm2.
hom cell twg yog hom 2 alveolar cells?
Hom II hlwb yog spherical pneumocytesuas tsuas yog 4% ntawm thaj chaw alveolar, tab sis lawv yog 60% ntawm alveolar epithelial hlwb thiab 10-15% ntawm tag nrho cov ntsws..
Dab tsi yog qhov txawv ntawm hom 1 thiab hom 2 alveolar hlwb?
Qhov sib txawv tseem ceeb ntawm hom 1 thiab hom 2 pneumocytes yog qhov hom 1 pneumocytes yog nyias thiab flattened alveolar hlwb uas yog lub luag haujlwm rau kev sib pauv roj ntawm alveoli thiab capillaries, thaum hom 2 pneumocytes yog cuboidal alveolar cells uas yog lub luag haujlwm rau kev tso tawm ntawm pulmonary surfactants uas…

Puas yog tshuaj tua kab mob tib yam li tshuaj tua kab mob?
Ib tshuaj tua kab mob yog siv rau lub cev, thaum cov tshuaj tua kab mob yog siv rau qhov chaw tsis muaj sia, xws li cov txee thiab cov tes tuav . Puas piv txwv ntawm tshuaj tua kab mob thiab tshuaj tua kab mob? Ob qho tshuaj tua kab mob thiab tshuaj tua kab mob zoo sib xws tab sis lawv nyiam sib txawv hauv lawv qhov kev xav.
Yuav tshuaj tua kab mob plawv puas tua kab mob kab mob?
Tsis yog txhua qhov kev tiv thaiv kab mob plawv kho thiab tswj cov kab mob sib kis. HEARTGARD® Plus (ivermectin/pyrantel) pab tiv thaiv kab mob plawv THIAB kho thiab tswj ob hom kab mob kab mob. HEARTGARD Plus yog cov nqaij nyuj tiag tiag uas dev hlub, 4 yog li yooj yim muab .
Puas muaj ntau hom kab mob los yog kab mob unicellular?
"Unicellularity tau ua tiav tiav - cov kab mob unicellular muaj ntau ntau dua li cov kab mob ntau lub cev, thiab tau nyob ib puag ncig tsawg kawg yog 2 billion xyoo ntxiv," hais tias tus thawj coj tshawb fawb Eric Libby, tus kws paub txog lej biologist ntawm lub koom haum Santa Fe hauv New Mexico .
Puas yog kab mob qhua pias thiab kab mob qhua pias los ntawm tib tus kab mob no?
Ntxhais kab mob yog kab mob kab mob ntawm daim tawv nqaijtshwm sim los ntawm tus kab mob cowpox lossis kab mob catpox. Qhov no yog ib tug tswv cuab ntawm tsev neeg Orthopoxvirus, uas suav nrog tus kab mob variola uas ua rau cov kab mob me. Cowpox zoo ib yam li tab sis mob me dua li kis tau zoo heev thiab qee zaum ua rau tus kab mob me me tuag taus .
Puas yog tus kab mob plague yog tus kab mob lossis kab mob?
Kab mob plague yog tshwm sim los ntawm cov kab mob Yersinia pestis, cov kab mob zoonotic feem ntau pom hauv cov tsiaj me thiab lawv cov dev. Cov neeg kis tus kab mob Y. pestis feem ntau tshwm sim tom qab lub sij hawm incubation ntawm ib mus rau xya hnub.
