Full Answer

Much like humans, frogs have a respiratory system that is designed for efficient transport of oxygen from the mouth to lungs. The trachea is an essential component of that system serving the role of connecting the and glottis to lung alveoli. The alveoli are the site of exchange of oxygen and carbon dioxide between blood and air in lungs. Unlike humans, frogs are capable of breathing through their skin and are not as dependent on the respiratory tract for survival as humans.

    What is the function of a frog's lung?

    A:

    A frog's lungs are involved in many functions, including breathing, vocalizing and hearing. Brown University explains that frogs use their lungs in the same way humans do to take in air. The breathing process is different, though, because a frog does not have ribs or a diaphragm like a human does, and these body parts help control air flow.

  • Q:

    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.
