alleryThe heart of a rabbit is:
ATwo chambered with one auricle and one ventricle
BThree chambered with two auricles and one ventricle
CSingle chambered without any septum
DFour chambered with two auricles and two ventricles
Answer & Solution
Correct answer: D. Four chambered with two auricles and two ventricles
1. The rabbit heart lies in the thoracic cavity between the lungs.
2. It has two auricles separated by an interauricular septum.
3. It also has two ventricles separated by an interventricular septum, making four chambers.
4. A three-chambered heart belongs to amphibians, not mammals, so that option is the trap.
