Question

why the ventricles in heart are thinner than auricles

Answer 1

Hey mate..
=========

▪Ventricles in heart are thinner than auricles because Ventricles donot need to pump blood into various organs of the body.

▪Instead, Ventricles have valves which ensure that the blood flows only in one direction.

▪Consequently, Auricles have thick, elastic walls because they need to pump oxygenated blood to various organs of our body.
