Bargo: wasanin gwada ilimi jira bincike

A duban farko, sunan na jiki na kasar, domin da bargo ba mallaki ayyuka na kwakwalwa. Amma duk da haka da sunan ne gaba daya ma'ana ƙa'ida, kamar kwakwalwa da aka kewaye da ƙashi na daga cikin kwanyar, saboda bargo ne ma "boye" a wani m. Wani lokacin mutane ba su da wani sosai bayyananne ra'ayin tsarin da kuma ayyukan da wannan tsari. Bari mu yi kokarin gyara shi a cikin wannan labarin.

A total taro na jiki a ɓõye, a cikin kasusuwa ne ba kamar yadda kananan kamar yadda na iya ze mafi yawan mutane - a matsayin masu yawa kamar yadda 4% na taro, wanda ke nufin cewa jiki na da talakawan mutum (70kg) ya nauyi ne 2.8 kg - quite mai yawa.

Bargo ne na biyu iri. Daya daga cikin wadannan iri ne, tsananin magana, wani jiki ba za a iya dauke, ko da yake yana da wani sulusi da murabba'i da nauyin 2.8 kg. Muna magana ne game da bargo ne rawaya. A gaskiya shi ne mai Kwayoyin. Amma akwai wani irin abin da histology tare dauke da wani raba jiki, saboda yana aiki tare da m aiki na hematopoiesis.

Me muka yi amfani da kalmar "m"? Gaskiyar cewa jini ne kai tsaye aiki siffofin da m kara Kwayoyin. Kuma su ne sosai sabon abu. Hukunci da kanka: wata al'ada tantanin halitta zai iya raba kawai goma sha biyar sau, amma a kara Kwayoyin babu irin wannan hane-hane, kamar yadda babu wani daya ya ciwon daji. Watakila wannan ne ya sa haka kowa ciwon daji na bargo?

A ranar nan aka kafa zuwa rabin biliyan sabon jini Kwayoyin, shi ne ba abin mamaki ba cewa, taro na jiki ne quite manyan. Red bargo ne sosai kawota tare da jini, wanda yake shi ne peculiar ga samar da ruwa, da sabon Kwayoyin zo a cikin general jijiyoyi. Akwai kuma daya daga cikin cibiyoyin da lymphatic tsarin - wani ɓangare na wani tasiri rigakafi da tsarin.

Hakika, a cikin ja bargo an kafa ba kawai lymphocytes. Saboda haka, iri uku Kwayoyin faruwa: fari jere na ja da platelet. Red erythrocytes samu, "m" don gudanar da oxygen, da fari - farin jini Kwayoyin-majiɓinta, (ciki har da lymphocytes) da kuma na platelet - Kwayoyin alhakin jini clotting, wanda taimaka jiki a yanayi na jini hasãra.

Ba duk rigakafi Kwayoyin kewaya a cikin jiki. Babbar dama su ga lokaci kasancewa qarya a cikin bargo. A gaskiya ma, akwai 50 sau mafi neutrophils (leukocytes view) fiye da a jini, saifa, da hanta. Wannan "musamman detachment" cewa vigilantly kare mu daga intrusion na pathogens. Sun amsa nan take, kuma na farko bar bargo, don kai farmaki makiya. Akwai zahiri "ci" da abokan gaba, wannan ne ake kira phagocytosis.

Kafin haihuwar jariri samar da maikacin jini ne ke da alhakin hanta. A hankali, duk da haka, tafiyar matakai na hematopoietic (jini kafa gabobin) akwai damped, kuma kawai ja bargo na aiki dare da rana a kan halittar kara Kwayoyin daga jini. Fitarwa daga wannan jikin ba, idan akwai ta zo a braking aiki, wannan yana nufin cewa jiki ne mai tsanani da matsala ba kuma cikin gaggawa bukatar daukar matakan magance halin da ake ciki. Saboda haka, mai tsanani jini cututtuka suna bi don haka mugun. Bayan transplanting da bargo ba wuya - wuya zuwa tsara don haka da cewa shi makale. Mun san cewa shi ne wani bangare ne na rigakafi da tsarin, kuma shi ne musamman mutum da makawa rikici. Saboda haka, kokarin dashi bargo na musamman daga cikin mafi kusa dangi.

A haihuwa, kuma mafi yawan bargo - mai ja, rabin balagaggu riga ya juya rawaya. Duk da haka, a cikin kwarai lokuta, da jiki ya bada umurnin - da kuma rawaya bargo ba zato ba tsammani yana ja sake. Ta yaya? Yana da wani m - da kuma ta ke jiran da za a bincika. A general, da jini tsarin, wanda ya hada da wani fitar kasusuwan jikinsu mutum kwakwalwa ne sosai hadaddun da kuma cike da asirai. A mafi binciken aka sanya, da mafi m aka saukar a gare mu.
