why don't arctic animals feet freeze in winter biology question
Homework Answers
The feet of arctic animals are equipped with an impresseive supply of blood vessels, which are surrounded by soft yet tough padding. The pressence of extra fur and padding in the paws of arctic animals keeps their feet from freezing.
The legs of these animals work like a heat exchange system. They possess closely woven, narrow blood vessels in the feet, which cool the blood from the body on the way to the feet and heats the blood as it returns to the body. The feet receive cool blood, so less heat is lost, as a result of which the body stays warm.
