Birds have a 4- chambered heart so the blood doesn't mix
Frogs have a 3- chambered heart so the blood mixes
yes it is but i have forgotten why
Frogs have a heart and blood vessels like all other vertebrates. The heart pumps deoxygenated blood from the body to the lungs, and then pumps oxygenated blood from the lungs to the body. However, frogs only have a three chambered heart, which permits oxygen rich and oxygen poor blood to mix. This is less effecient than the four chambered hearts of mammals and birds.
