Question
What is the significance of the two atria in the amphibian heart?Multiple choice question.The oxygenated and deoxygenated blood do not mix in the atria.The oxygenated and deoxygenated are fully mixed in the atriaThe oxygenated and deoxygenated blood are partially mixed in the atria.
Solution
The correct answer is: The oxygenated and deoxygenated blood are partially mixed in the atria.
In amphibians, the heart consists of two atria and one ventricle. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs and skin. These two types of blood are partially mixed in the ventricle before being pumped out to the body. This is different from mammals, where the heart has two separate ventricles to prevent the mixing of oxygenated and deoxygenated blood.
