How would you describe the heart's ventricles?

1 Answer

Answer :

The cardiac ventricles are the two lower chambers of the heart's four chambers. They are larger and more narrowed than the atria. They function by collecting the blood that flows into them from the atria and then contract in order to expel blood into the peripheral tissues, using major vessels to carry it to the extremities and lungs.
