Amphibians excrete nitrogen in the form of ammonia or urea. The excrete ammonia as the major metabolic waste.

Amphibians have a closed double circulation; blood flows from the heart to the gills or lungs for gas exchange, then back to the heart to be repressurized before flowing to the rest of the body.

Most amphibians require fresh water to lay their eggs. Males arrive breeding sites before females and the vocal chorus they produce may stimulate ovulation in females. Frogs use external fertilisation. Oviparous
