Extension describes the increasing of a joint's angle. It refers to the movement that opens or straightens a joint, increasing the angle between the bones involved.

Explanation
A sheep's heart has two ventricles. This is because, like most mammals, sheep have a four-chambered heart consisting of two atria and two ventricles. The ventricles are the lower chambers of the heart responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. Having two ventricles allows for efficient separation of oxygenated and deoxygenated blood, ensuring proper circulation throughout the body.
