Question

Give reason -
Ventricles have thicker walls than auricles.

Answer 1

Answer:

The lower chambers are the right and left ventricles, which receive blood from the atria above. Their muscular walls are thicker than the atria because they have to pump blood out of the heart. Although the left and right ventricle are similar in structure, the walls of the left ventricle are thicker and stronger.

Hope its is helpfull

Answer 2

Answer:

The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle,
