Lawv txoj haujlwm yog thauj cov pa oxygen mus rau lub cev cov ntaub so ntswg sib pauv cov pa roj carbon dioxide, uas tau nqa mus thiab tshem tawm ntawm lub ntsws. Cov qe ntshav liab tau tsim nyob hauv cov pob txha liab ntawm cov pob txha. Stem cells nyob rau hauv cov pob txha liab hu ua hemocytoblasts ua rau tag nrho cov tsim nyob rau hauv cov ntshav.
Tsis tas li, dab tsi yog qhov tseem ceeb ntawm hematopoiesis?
Hematopoiesis - kev tsim cov khoom sib xyaw ntawm cov ntshav - tshwm sim thaum lub sijhawm embryonic kev loj hlob thiab thoob plaws lub hnub nyoog laus los tsim thiab ua kom cov ntshav rov zoo li qub. Kawm hematopoiesis tuaj yeem pab cov kws tshawb fawb thiab kws kho mob kom nkag siab zoo dua cov txheej txheem tom qab muaj teeb meem ntshav thiab qog noj ntshav.
Kuj Paub, ua haujlwm ntawm cov hlwb myeloid yog dab tsi? Myeloid hlwb, suav nrog neutrophils, monocytes, macrophages, myeloid dendritic cells (mDCs), thiab mast cells ua ke ua ib qho tseem ceeb. caj npab ntawm tiv thaiv kab mob , feem ntau yog lub luag hauj lwm rau innate tiv thaiv ib array ntawm pathogens.
Raws li qhov no, yog vim li cas hematopoietic qia hlwb tseem ceeb?
Hematopoietic Stem Cells . Hais txog kev ua haujlwm, cov no hlwb yog lub luag haujlwm rau txuas ntxiv txuas ntxiv ntawm erythrocytes, leukocytes, thiab platelets hauv lub cev los ntawm cov txheej txheem hu ua hematopoiesis. Lawv kuj ua si ib tseem ceeb Lub luag haujlwm hauv kev tsim cov kabmob tseem ceeb xws li lub siab thiab tus po thaum lub sijhawm kev loj hlob ntawm fetal
Hemocytoblasts nyob qhov twg?
Hemocytoblasts yog nyob nyob rau hauv cov pob txha liab ntawm tav, sternum, vertebrae, thiab ilium ntawm cov neeg laus. Lawv yog pom nyob rau hauv tag nrho cov chaw ntawm cov me nyuam, tab sis kuj nyob rau hauv lawv tibia thiab fibula.

Lub cev tseem ceeb ntawm lub plab zom mov yog dab tsi thiab lawv lub luag haujlwm yog dab tsi?
Cov khoom siv hauv lub cev zom zaub mov suav nrog cov hniav, tus nplaig, cov qog ua kua qaub, daim siab, lub zais zis, thiab txiav txiav. Txhawm rau ua tiav lub hom phiaj ntawm kev muab lub zog thiab khoom noj khoom haus rau lub cev, rau lub luag haujlwm tseem ceeb nyob hauv cov txheej txheem zom zaub mov: nqos. Kev zais. Sib tov thiab txav mus los. Digestion. Kev nqus. Kev tshem tawm
Dab tsi yog qhov tseem ceeb lom tseem ceeb ntawm Glycogenesis?
Lub hom phiaj tseem ceeb ntawm glycogenesis yog kom ntseeg tau tias lub cev tsis muaj piam thaj. Glucose yog qhov tseem ceeb vim nws yog lub cev qhov tseem ceeb ntawm lub zog. Yog tias tsis muaj cov piam thaj txaus hauv lub cev, cov kabmob tseem ceeb yuav raug kaw thaum kawg
Qhov sib txheeb ntawm pKa thiab pI qhov tseem ceeb hauv cov protein yog dab tsi?
PI ntawm cov protein tau txiav txim siab los ntawm kev sib sau pH (thiab yog li pKa) ntawm txhua cov amino acid hauv cov saw hlau. Txhua cov amino acid nws muaj nws tus kheej pKa (thiab pI), tab sis tuaj yeem sib txawv raws li pes tsawg lwm cov amino acids nyob ib puag ncig koj lub hom phiaj amino acid
Qhov tseem ceeb ntawm qhov sib txawv ntawm tuab ntawm phab ntsa ntawm aorta yog dab tsi?
Dab tsi yog qhov tseem ceeb ntawm qhov sib txawv ntawm tuab ntawm phab ntsa ntawm aorta thiab phab ntsa ntawm lub ntsws ntsws? Cov phab ntsa tuab ntawm aorta tso cai kom tiv taus siab dua ntawm cov ntshav tso tawm los ntawm lub ventricle
Qhov txawv ntawm kev tswj hwm qhov xwm txheej tseem ceeb thiab kev kho yog dab tsi?
Kev kho hlwb yog ib txwm xa los ntawm kws tshaj lij kho mob hlwb, tab sis CISM tuaj yeem muab los ntawm cov kws tshaj lij ntawm txhua yam. Lub hom phiaj ntawm CISM yog los tswj cov kev raug mob tam sim ntawd thiab txo kev ntxhov siab, qhov kev kho puas siab puas ntsws cuam tshuam nrog ntau yam ntawm cov hom phiaj luv luv thiab ntev mus rau kev loj hlob thiab kev hloov pauv
