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).

Structure of Frog's Heart
The frog's heart consists of two auricles and one ventricle. This unique structure allows for the circulation of oxygenated and deoxygenated blood in the frog's body.
Two Auricles
- The frog's heart has two auricles, which are the upper chambers of the heart responsible for receiving blood from the veins.
- One auricle receives oxygenated blood from the lungs and skin, while the other auricle receives deoxygenated blood from the body.
One Ventricle
- The frog's heart has only one ventricle, which is the lower chamber responsible for pumping blood out of the heart.
- The ventricle pumps a mixture of oxygenated and deoxygenated blood to the different parts of the frog's body.
Circulation in Frog's Heart
- In the frog's heart, the oxygenated and deoxygenated blood mix in the single ventricle before being pumped out to the body.
- This mixed blood is then circulated to the lungs and skin for oxygenation before returning to the heart for another cycle.
Efficiency of Frog's Heart
- Despite having only one ventricle, the frog's heart is able to efficiently circulate blood throughout its body.
- This unique structure allows the frog to adapt to its environment and meet its metabolic needs effectively.
