Amphibians generally have three chambers in their hearts. What type of chambers they are?
Correct answer: A. One ventricle, two atria
- A. One ventricle, two atria
- B. Two ventricles, one atrium
- C. One ventricle, one atrium
- D. One ventricle, one atrium, one sinus venosus
Explanation
Amphibians typically have a heart with three chambers, which includes one ventricle and two atria. This structure allows for some mixing of oxygenated and deoxygenated blood, which is suitable for their metabolism and lifestyle. In contrast, the hearts of birds and mammals have four chambers (two atria and two ventricles) to completely separate oxygenated and deoxygenated blood. The incorrect options either suggest an incorrect number of chambers or misidentify the sinus venosus as a primary chamber.
