Circulatory System. This system is made up of the heart, blood, blood vessels, and lymphatics. It is the bodyâs delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.
The circulatory system has a close interrelationship with the respiratory system. The main organ of the respiratory system is the lungs. The diaphragm is a muscle located underneath the heart and lungs that contracts to pull air into the lungs and relaxes to force air out of the lungs.When the air enters the lungs, it travels through the bronchi to tiny air sacs called alveoli.irculatory System. The circulatory system consists of the heart, blood, and blood vessels. There are three types of blood vessels: arteries, veins and capillaries. The heart is an organ made of cardiac muscle and it acts like a pump.
