The frog’s digestive tract is very well vascularized for a few reasons. First the frog’s digestive tract is very long and convoluted which means that there is a lot of surface area for the blood to come into contact with. Second the frog’s digestive tract is very thin which also increases the surface area that the blood can come into contact with. Third the frog’s digestive tract is full of many small blood vessels called capillaries which allow for a very efficient exchange of nutrients and wastes between the blood and the digestive tract.
All of these factors together make the frog’s digestive tract very well suited for absorbing nutrients from food and for getting rid of wastes. The frog’s digestive tract is so efficient in fact that frogs can absorb up to 80% of the nutrients from their food! This is why a healthy diet is so important for frogs – if they don’t get enough nutrients they won’t be able to grow and stay healthy.
