Extract

Elpošanas sistēma
vairākums abinieku elpo ar plaušām un ādu;
plaušas ir iegareni maisi, elastīgām sienām, tomēr vāji attīstītas;
papildus gāzu maiņa notiek caur mitro ādu;
abinieku kāpuri elpo ar žaunām.

Asinsrites sistēma
abinieku sirds sastāv no trīs kamerām: diviem priekškambariem un viena kambara;
asins no visiem orgāniem saplūst vēnas un ieplūst labajā priekškambarī;
abiniekiem ir divi asinsrites loki – lielais un mazais asinsrites loks.
