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 supplies blood which contains oxygen, nutrients, and other substances to the different cells of the body. 2. An open circulatory system allows blood to be distributed to the different organs in a lower pressure. 3. In a closed circulatory system, blood passes through blood vessels and moves due to a difference in blood pressures.
