Cov ntau lawm ntawm tsim ntsiab , los yog ntshav cov hlwb, hu ua hemopoiesis. Ua ntej yug los, hemopoiesis tshwm sim feem ntau hauv daim siab thiab tus po, tab sis qee lub hlwb tsim hauv cov thymus, qog ntshav, thiab pob txha liab liab.

Tsis tas li ntawd nug, cov ntsiab lus tsim nyob rau hauv cov ntshav tsim nyob qhov twg?

Los ntawm cov txheej txheem ntawm hemopoiesis, cov tsim ntsiab ntawm ntshav tau tsim tawm tas li, hloov pauv qhov nyob luv luv erythrocytes, leukocytes, thiab platelets. Hemopoiesis pib nyob rau hauv cov pob txha liab, nrog hemopoietic qia hlwb uas sib txawv rau hauv myeloid thiab lymphoid kab.

Ib yam li ntawd, peb lub ntsiab tsim hauv cov ntshav yog dab tsi? Cov tsim ntsiab yog cov hlwb thiab cov kab mob ntawm tes raug tshem tawm hauv plasma. Cov peb chav kawm ntawm tsim ntsiab yog cov erythrocytes (liab ntshav cell), leukocytes (dawb ntshav cell), thiab thrombocytes (platelets).

Ib yam li ntawd, nws raug nug, lub cev dab tsi tsim cov ntsiab lus ntawm cov ntshav?

Hematopoietic tshuaj Qhov system ntawm Bone Marrow Hemopoiesis yog kev nthuav dav thiab sib txawv ntawm cov tsim ntsiab ntawm ntshav.

Cov ntshav tsim li cas?

Cov txheej txheem ntawm kev ua ntshav cov hlwb hu ua hematopoiesis. Ntshav cov cell tau ua hauv cov pob txha pob txha. Cov no ntshav - sib sau qia hlwb tuaj yeem loj hlob mus rau txhua 3 yam ntshav cell - cell liab, dawb cell thiab platelets. Cov no ntshav - sib sau qia hlwb ua luam ntawm lawv tus kheej, thiab lawv kuj tsim mature ntshav hlwb.

Dab tsi yog lub npe ntawm cov khoom tsim uas yog qhov tseem ceeb rau kev pib tsim cov ntshav khov?

Thrombocytes (platelets) Megakaryocytes tsim los ntawm hemocytoblasts hauv cov pob txha liab. Thrombocytes dhau los ua nplaum thiab sib sau ua ke los ua cov platelet ntsaws uas kaw qhov tawg thiab kua muag hauv cov hlab ntshav. Lawv kuj pib tsim cov ntshav txhaws

Lub qhov hluav taws xob nyob qhov twg nyob qhov twg?

Lub plab feem ntau yog nyob rau sab laug sab saud sab hauv qab lub diaphragm thiab txuas nrog zoo dua rau txoj hlab pas thiab nyob deb rau duodenum

Qhov feem pua ntawm cov ntshav tau tsim los ntawm cov khoom tsim?

Cov qe ntshav no (uas tseem hu ua corpuscles lossis 'tsim cov ntsiab lus') suav nrog erythrocytes (cov qe ntshav liab, RBCs), leukocytes (cov qe ntshav dawb), thiab thrombocytes (platelets). Los ntawm qhov ntim, cov qe ntshav liab muaj li ntawm 45% ntawm cov ntshav tag nrho, cov ntshav plasma txog 54.3%, thiab cov qe dawb txog 0.7%

Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?

Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
