Endocrine signaling relies on glands that release hormones directly into the bloodstream to regulate body processes. The pituitary gland is a central endocrine gland often called the master gland because it produces hormones that control many other glands and body functions. Among the options, the pituitary gland best fits as an endocrine gland. The stomach, bladder, and heart are not primary endocrine glands, even though they may be involved in other hormonal interactions or physiological roles.
