Q:

What is the function of frog skin?

A:

Quick Answer

The skin of a frog has two primary functions: helping the frog to drink and helping the frog to breathe. Toads also use their skin in these two ways, though they are able to retain moisture better than frogs and do not need to be as close to a water source.

It is important that each frog maintain a proper level of moisture in their skin in order to breathe. Without this level of moisture, the frog can suffocate and perish. The frog uses its skin as well as its lungs and mouth lining in order to breathe. When the frog is underwater, it uses its skin only to breathe by allowing gasses to permeate the body as well as leave it. When out of the water, the frog uses mucus glands to dissolve oxygen that is already present in the air and then to absorb it. Frogs also need to be able to breathe whenever they are hibernating and breathing through their skin is the only option when they are buried in mud for hibernation.

The frog also uses its skin to drink because frogs do not drink water or other liquids through their mouths. The frog has a patch on its stomach and part of its thighs where it can absorb water. These areas are commonly referred to as the "drinking patch areas."

  • Q:

    How has a frog adapted to its environment?

    A:

    Different frogs have different adaptations, but generally frogs have eyes on the top of their head for seeing out of the water, a long, sticky tongue for capturing prey such as insects and sensitive skin for absorbing water and oxygen. According to BioWeb ULAW, many frogs such as the Northern Leopard Frog have powerful legs that help them adapt to their environment both by jumping in a zigzag pattern to avoid being eaten on land, and also for swimming skilfully enough to catch their own prey in water.

    How does blood circulate through a frog?

    A:

    Blood starts in a frog's heart where it gets sent off to either the lungs or the skin to become oxygenated, then it gets sent back to heart to be mixed with less oxygenated blood before being pumped to all organs and extremities through blood vessels. Once the blood has been used by organs and muscles, the newly deoxygenated blood is transported back to the heart.
