ABO cov ntshav pab pawg koom nrog ob antigens thiab ob qhov tshuaj tiv thaiv pom hauv tib neeg cov ntshav. Cov ob antigens yog antigen A thiab antigen B.
Tom qab ntawd, ib tug kuj yuav nug, pes tsawg pawg ntshav antigens muaj?
Muaj yog peb ntshav pawg antigens hauv tib neeg, O, A, B, thiab AB system.
Ib tus kuj yuav nug, cov ntshav antigens tsim tau li cas? Cov ntshav antigens pawg yog cov suab thaj los yog cov proteins, thiab lawv txuas nrog ntau yam hauv cov xim liab ntshav cell membrane. Piv txwv li, lub antigens ntawm ABO ntshav pawg yog suab thaj. Lawv yog tsim los ntawm ib tug series ntawm cov tshuaj tiv thaiv nyob rau hauv uas enzymes catalyze hloov cov piam thaj units.
Tsis tas li ntawd, dab tsi antigens nyob hauv cov ntshav?
Cov ntshav pawg A muaj A antigens ntawm cov qe ntshav liab nrog cov tshuaj tiv thaiv. B cov tshuaj tiv thaiv kab mob hauv cov ntshav. Lwm yam (thiab tseem ceeb) hom kev faib ntshav yog Rhesus lossis Rh cov ntshav txheej txheem. Tab sis tsis yog txhua cov ntshav yog tib yam, thiab tau muab cais ua ntau hom lossis pab pawg.
Muaj pes tsawg pab pawg ntshav muaj?
International Society of Ntshav Kev hloov ntshav tsis ntev los no tau lees paub 33 ntshav pab pawg . Sib nrug los ntawm ABO thiab Rhesus lawv , ntau lwm yam hom ntawm antigens tau pom ntawm cov cell liab.

Muaj pes tsawg grams yog pes tsawg pea?
Qhov no yog qhov tseem ceeb tshwj xeeb rau cov menyuam yaus, sowing 'pea-sized amount' feem ntau pom zoo. Txawm li cas los xij, muaj cov lus qhia me me hais txog qhov no txhais li cas hauv kev xyaum, txawm hais tias nws tau qhia tias yog 0.25 g
Muaj pes tsawg tus paub tib neeg cov pab pawg ntshav muaj?
International Society of Blood Transfusion tsis ntev los no tau lees paub 33 pawg kab mob. Sib nrug los ntawm ABO thiab Rhesus system, ntau lwm hom antigens tau pom ntawm daim tawv nqaij liab
Muaj pes tsawg cov protein nyob hauv cov qe ntshav liab?
Tam sim no muaj ntau dua 50 lub npe hu ua cov protein, uas tuaj yeem muaj nyob hauv ob peb puas txog ib lab luam ntawm ib lub qe ntshav liab. Kwv yees li 25 ntawm cov protein no ua rau muaj ntau hom ntshav antigens, xws li A, B thiab Rh antigens, thiab ntau lwm yam
Muaj pes tsawg txheej ntawm cov leeg nqaij hauv plab hauv tus menyuam hauv plab?
Nws txuas ntxiv tom qab mus rau pectoralis loj, pib los ntawm lub sternum thiab tso rau ze ze ntawm qhov kawg ntawm lub humerus, tseem ua rau lub hauv pliaj. Muaj peb txheej txheej ntawm cov leeg uas ua rau sab phab ntsa ntawm lub plab, thiab cov leeg nqaij thib plaub ua rau sab nrauv ntawm phab ntsa
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
