Yes, the heart is considered an endocrine gland. While primarily known for its role in pumping blood throughout the body, the heart also secretes hormones.
One notable hormone produced by the heart is atrial natriuretic factor (ANF), which is released from the atria. ANF plays a crucial role in regulating blood pressure and fluid balance within the body.
The discovery of ANF led to the recognition of the heart as an endocrine gland, as it actively produces and releases hormones that influence other organs and systems.
