Wood Frog Heart at Glen Chambers blog

Wood Frog Heart. This transition requires major changes in biochemistry. The wood frog, rana sylvatica, is the best studied model of freeze tolerance among vertebrate species and we begin our discussion. Notably, wood frogs achieve maximum ice content of about 65 % of total body water well within the 24 h time at −2.5 °c. The frog’s eyes glaze over, its brain freezes, and ice pushes blood to the frog’s heart before eventually that, too, is rock solid. As temperatures drop, their bodies produce increasing amounts of glucose, which acts as a natural cryoprotectant. The frog’s heart stops beating and its body functions shut down, a unique adaptation that enables the wood frog to survive frigid temperatures in its north. As winter progresses, the wood frog’s heart stops beating, and their breathing ceases. This glucose helps prevent dehydration and protects their vital organs from freezing.
