Oxygen and carbon dioxide are exchanged across the lining of a frog's mouth. Oxygen is absorbed from the air into the blood vessels, while carbon dioxide is released into the air from the blood vessels.
The frog's skin has many small blood vessels so that oxygen can go through the thin skin, through the fine blood vessels, and into the blood stream, allowing for the frog to breathe more easily.
The spleen is the organ found within the mesentery that stores blood in a frog. It acts as a reservoir for blood and also plays a role in immune function by filtering the blood and removing old or damaged red blood cells.
