Inkqubo ye-lymphatic yomntu yinkqubo yesimo senhliziyo. Idlala umsebenzi obalulekileyo ekuhlanjululeni izicubu zomzimba nakwi-metabolism. Ngokungafani negazi, le nxalenye ayivaliwe kwaye ayisebenzisi ipompo ephambili yokuhamba kwayo. Umbane uhamba kancane phantsi kwefuthe lexinzelelo elincinci.
Ulwakhiwo lwe-lymphatic system system
Le nxalenye yomzimba iqukethe:
- iinqanawa ezihambelanayo kunye nama-capillari apho i-liquid ihamba khona;
- i-lymph nodes ezibandakanya ukuhluthwa;
- ezimbini iilymatic ducts;
- yilezi zixhobo ezinokuthi zijikeleze umzimba.
Ukongezelela, izitho zenkqubo ye-lymphatic yoluntu ziquka i-thymus, i-tonsils ne-pen.
Ngokwahlukileyo kuyimfuneko ukuthetha malunga nesakhiwo se-lymph node. Yenza imisebenzi ebalulekileyo, ejoliswe ikakhulu kwisakhiwo. Ngoko, le nxalenye yenkqubo iqukethe izicubu ze-lymphoid. Ngaloo nto limelelwe kwifom yeeseli ze-plasma kunye nama-reticulocyte. Kule ndawo yenkqubo apho umthamo we-B-lymphocytes ukwandisa, okuphucula umkhuhlane . Ngethuba lokuguqulwa okuqhubekayo, zivelisa izixhobo zokulwa.
Kuloo node nganye kukho i-T-lymphocytes, leyo, ekudibanisaneni ne-antigen, iyahlukahluka. Ngaloo ndlela, la malungu omzimba athatha inxaxheba ekubunjweni kwamagciwane omzimba.
Ukongezelela, kubalulekile ukukhankanya ukwakhiwa kwe-lymph. Olu lukhuni luyingxenye yezicubu ezinxibelelwano. Iqulethe i-salts kunye nezixazululo ze-colloidal zeeprotheyini ezinika i-viscosity. Ukubunjwa kwakhona kuninzi amanqatha. Umbane ufana ne-plasma yegazi.
Emzimbeni womntu ngamnye ufikelela kwiililitha ezimbini ze-lymph. Ukunyakaza kwayo kwenzeka ngeempahla ngenxa yokuqhekeka kweeseli zamascle ezindongeni. Inendima ebalulekileyo kulo mbandela idlalwe ngumsebenzi wezidumbu, ukuphefumla kunye nesimo somzimba wonke.
Imisebenzi yesistim somzimba
Inkqubo ye-lymphatic, nangona kubonakala ngathi ekubonweni kokuqala akubalulekanga njengenkqubo ye-nervous or circulatory, nangona kunjalo idlala indima ebalulekileyo ekusebenzeni kakuhle komzimba ngamnye:
- Into ephambili eyenzayo iqinisekisa ukuphuma kwe-liquid excess and substances from space intercellular. Konke oku kungena emithanjeni yegazi.
- Ukukhuselwa komzimba kumachiza amaninzi angaphandle kunye nezinto ezingaqhelekanga. Kwiingcambu zale nkqubo, ezinye izinto ezinokulimaza umntu zilibazisekile. Ezi zixhobo zisebenza njengezihlunu zendalo.
- Ukukhula kwamaseli omzimba. Apha, i-leukocyte ekhethekileyo yenziwa, eyokungena kwigazi. Ukuba kuyimfuneko, zivelisa izixhobo ezinokuzibopha kunye nokunciphisa ama-microorganisms angaphandle.
- Enye inxalenye enkulu yenkqubo ye-lymphatic yoluntu uncedo kumba wokuxutywa kwamanqina. Iiprotheni kunye ne-carbohydrate zingena kwinkqubo yejikeleziyo emathunjini. Yaye ininzi yemifino ifakwe ngokuthe ngqo kwiinqanawa ze-lymphatic. Ngaphezulu, kunye ne-liquid ehambelanayo, sele sele egazini.
- Ukuthuthwa kweeprotheni ezinkulu kwii-corpuscles ezibomvu. Izinto ezininzi azikwazi ukungena kwi-capillary kwi-intercellular space. Kwaye kufuneka ukuba kubekho kwinkqubo yokujikeleza - oku kubalulekile ekusebenzeni kakuhle. Iiprotheni ezinkulu zivela egazini ngexabiso le-lymph, ekubeni i-capillaries ehambelana nale nkqubo iyakwazi ukweqa izinto ezifunekayo.
Kubalulekile ukuba umbane uhamba ngokuthe rhoqo, kwaye nakuphi na umzekelo, ungavumeli ukuhlaselwa. Inqaku elipheleleyo kukuba ukuba i-lymph ishukunyiswa ngokukhawuleza emzimbeni, ingakhokelela ekuvukeleni okukhulu kwezi nodes , eziya kufuna ukuba zisuswe.
