Heart

The heart is a vital organ in the circulatory system of a vessel. It is responsible for pumping blood throughout the vessel, delivering oxygen and nutrients to the body's tissues and removing carbon dioxide and other waste products. The heart is made up of four chambers: the right atrium, the left atrium, the right ventricle, and the left ventricle. The atria receive blood from the body and lungs, while the ventricles pump blood out to the body and lungs. The heart is essential for the vessel's survival, and any damage or malfunction can have severe consequences.
