The heart is the organ that applies pressure to the circulatory system.
Circulatory system :)
The endocrine system are glands that releases hormones into the circulatory system. The circulatory system then carries them into the organs. It regulates blood pressure, metabolism, and reproduction.
The pumping organ of the circulatory system is the heart. It generates the pressure to move blood through the circulation.
