A four-chambered heart, with a complete septum between the left ventricle and the right ventricle, makes the warm-blooded condition possible for all of the following vertebrate groups except:
modern placental mammals (like the beaver)
modern amphibians (like the frog)
modern monotremes (like the platypus)
modern birds (like the bald eagle)
modern marsupials (like the kangaroo)
Explain the effect that decreasing temperature had on the frog heart. How do you think the human heart would respond?
Explain the effect that increasing
temperature had on the frog heart. How do you think the human heart would respond?
Why Ringer’s solution is required to maintain heart contractions?
Amphibians have three-chambered hearts, which have some limitations when compared to the four-chambered hearts of birds and mammals. Describe a disadvantage of a three-chambered heart (in comparison to a four-chambered heart), and one way in which amphibians are able to compensate for it.
