Question
ssertion: Amphibians can tolerate mixing of oxygenated and deoxygenated blood.Reason: Amphibians are animals with two chambered heart
Solution
The assertion and reason given are partially correct.
Amphibians can indeed tolerate the mixing of oxygenated and deoxygenated blood, but the reason provided is not entirely accurate. Amphibians actually have a three-chambered heart, not a two-chambered heart. This three-chambered heart consists of two atria and one ventricle.
The mixing of oxygenated and deoxygenated blood occurs in the single ventricle of the amphibian heart. This is different from mammals and birds, which have a four-chambered heart that completely separates oxygenated and deoxygenated blood.
Despite this mixing, amphibians can still function effectively because they also respire through their skin and the lining of their mouth, which allows for additional oxygen uptake.
