Heart
The heart (Latin cor) is a hollow, muscular organ that pumps blood through the blood vessels by repeated, rhythmic contractions. The heart also secrets ANF, a powerful peptide hormone, that affects the blood vessels, the adrenal glands, the kidneys and the regulatory regions of the brain to regulate blood pressure and volume. The term cardiac means "related to the heart", from the Greek kardia (??????) for "heart".
