Vedclass · Answer

(B) $1$. The Assertion is true: The frog's heart is muscular and consists of three chambers ($two \ atria$ and $one \ ventricle$).$2$. The Reason is true: The $conus \ arteriosus$ is a structure that helps distribute blood from the ventricle to the rest of the body.$3$. However, the Reason is not the correct explanation for the Assertion. The three-chambered nature of the heart is an anatomical feature related to the evolutionary adaptation of amphibians, while the pumping of blood via the $conus \ arteriosus$ is a functional mechanism of the circulatory system. The number of chambers does not exist solely because of the $conus \ arteriosus$; rather, the $conus \ arteriosus$ is a component that manages the flow of the mixed blood resulting from the three-chambered structure.

Assertion: The heart of a frog is muscular and three-chambered.
Reason: The heart of a frog pumps mixed blood into the lungs and body via the $conus \ arteriosus$.
