Uyini hemolymph? Ukwakheka nemisebenzi hemolymph

Igazi-lymph emzimbeni womuntu imisebenzi ebalulekile ekugcineni umgudu wokuphefumula futhi mzimba. Nokho, akubona bonke izilwane, lolu ketshezi abahlukene, ngenxa ekwakhekeni nasekumeni komzimba inkimbinkimbi inhlangano. eziphilayo ezinjalo zihlanganisa abameleli ezifana eyisinambuzane (izinambuzane, izicabucabu, ezinamagobolondo) ne-shellfish. Basuke izimpawu khona hemolymph, okuyinto Kuningi ukufana okukhona phakathi kwengoma igazi nemisebenzi.

Hemolymph - kuyini?

Ukuze izilwane ezifana eyisinambuzane futhi molluscs, libhekene uhlelo non-ivaliwe kwegazi. Lokhu kusho ukuthi uketshezi ukuthi ukhiphela ngokusebenzisa izitsha, ikhishwe ku ngalo ingaphakathi umzimba futhi awashe zonke izidumbu kwezicubu. Lolu ketshezi libizwa hemolymph, njengoba ke ihlanganisa imisebenzi yegazi kanye lymph.

Uyini hemolymph izinambuzane nezimbaza? Iwuketshezi kungekho nto enemibala emihle, bluish noma ogqamile, okuyinto unomthwalo ukulethwa izakhamzimba kwezitho nezicubu yokushintshisana umzimba kanye amasosha omzimba kanye ukubukeka usongo isifo.

Hemolymph ezingenamgogodla futhi imbandakanya izakhi okwenyanga eyodwa zilwane, ngokungafani kuya igazi lomuntu futhi nezinye izinto eziphilayo evolutionarily athuthukile. La mangqamuzana abizwa ngokuthi amaseli egazi, bangase ihluke nomunye e isakhiwo, ifomu bese umsebenzi.

Ukwakheka hemolymph

Uyini hemolymph kusukela iphuzu amakhemikhali umbono? Ukwakheka lokhu isisombululo kunalokho nzima, ngoba Senza imisebenzi eminingana izinambuzane umzimba ezilwane ezingenamgogodla. Hemolymph has a imvelo hlangothi noma kancane azibukhali, okuyinto enakekelwa anions of acid ezithile. Kusukela 75 kuya 90% of the solution Imininingwane amanzi, futhi umthamo asele uwela izakhi okwenyanga nezinye solutes.

Ukwakheka ionic we hemolymph futhi ahlukahlukene. It cations kukhona sodium, potassium, magnesium kanye calcium. Okubaluleke enkulu anions chlorine, kanye izinsalela of acid wali band futhi carboxylic. Okuqukethwe zonke ion zishintsha futhi incike yobudala nasesigabeni sokukhula umzimba. Ngokwesibonelo, okuqukethwe chlorine anions kungaba esihlukile isinambuzane isibungu omdala.

Of udaba eziphilayo e-hemolymph kukhona amaphrotheni, amafutha kanye carbohydrate. Carbohydrate kanye amaprotheni faka ukudla ngokusebenzisa isimiso sokugaya ukudla bungene, lapho okuqukethwe yi-glucose ne fructose kuncike amanani umpe yokuqothulwa.

Ngo-100 ml hemolymph iqukethe 1-5 g amaprotheni. Amaphrotheni zidlala indima ebalulekile empilweni umzimba, ngakho basuke zithutha nge ukugeleza ketshezi kuya kwezitho nezicubu. Uma ucwaningo ukuziphatha haemolymph ungakwazi ukuhlukanisa phezulu Ngokuphathelene nezingxenyana ezikhishwa 30 ezahlukene amaprotheni, futhi nenombolo yabo incike yobudala kanye ocansini umzimba.

Lipids faka hemolymph kusukela esiswini kanye fat umzimba, futhi yokugcina bandisa phezu esaphila. Okuqukethwe amafutha kuyahlukahluka, kodwa iningi labo zimumethe esters ka glycerol futhi fatty acid - glycerides. Yilokho hemolymph kusukela umbono wesayensi yokuthakwa kwamakhemikhali.

imisebenzi hemolymph

Uyini hemolymph nalokho isebenta Senza emzimbeni ezingenamgogodla?

1. umsebenzi trophic, esakhiwa ngo ukusuthisa ezicutshini futhi izitho, kanye ukuthuthwa izinto ngomzimba.
2. Umsebenzi umzimba kwezicubu lapho hemolymph iwe metabolites futhi excreted ngokusebenzisa uhlelo excretory.
3. Umsebenzi immunological. Usekelwa ezinye izinhlobo hemocytes, okuyizinto phezu kwezitho.
4. Umsebenzi zokuzivikela. Hemolymph kwamanye eyisinambuzane futhi molluscs aqukethe ubuthi noma ezinye ezinobuthi ukuthi bazivikele ezilwaneni ezidla ezinye izilwane.

elementi kwakhiwa

Uyini hemolymph eziphilayo? Le isixazululo, equkethe hhayi solutes kuphela, kodwa namangqamuzana akhethekile - hemocytes. Kukhona 7 izinhlobo hemocytes umsebenzi wabo oyinhloko ukuzivikela komzimba ukuze antigen ukubukeka. Owenza izakhi kwakheka kwi evele kwezicubu ezithile phagocytic izakhiwo letisebenta futhi umsebenzi lymph node ezilwaneni ezinomgogodla.
