Unlike a frog, a tadpole has a<u> two chambered heart</u> (there is only one atrium and one ventricle).
The blood travels through the body as follows: All the blood in the body moves to the atrium, then the heart relaxes and the blood moves to the ventricle.
FROG:
The frog heart has 3 chambers: two atria and a single ventricle. The atrium receives deoxygenated blood from the blood vessels (veins) that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin (which also serves as a gas exchange organ in most amphibians). #answerwithquality #BAL
