Question

The ventricles have thick muscular walls whereas the auricles have thin walls why do you think thick muscular walls are necessary in the world and not in the auricle

Answer 1

Answer:

Explanation:

The left ventricle has thicker walls because it pumps blood to he whole body. The auricles need much less pressure because they do not pump blood to organs, they just need to pump blood to the next ventricle.

Answer 2

Answer:

auricles just have to push blood from auricles to ventricles which is a SHORT distance thus their walls are not muscular enough

but ventricles, on the other hand, have to push blood away from the heart to long distances (right ventricle sends blood to lungs and left ventricle sends blood to the entire body) thus, they are more muscular to facilitate this flow of blood
