The chambers that are very small, thin, and wrinkled are known as?

Explanation:
Thin-walled chambers that are built to receive blood with little pressure show a wrinkled inner surface from pectinate muscles. The atria are the heart’s receiving chambers located at the top, and their walls are indeed thin while the interior surface has that wrinkled look. In contrast, the ventricles have thick, muscular walls to generate high-pressure pumps, and the aorta and pulmonary trunk are arteries, not chambers. So the described features point to the atria.
