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.
Source(s): http://www.indiastudychannel.com/resourc... The circulatory system works very closely with the 'lymphatic system'. The lymphatic system basically collects all of the nutrients and good stuff that accidentally diffuses out of the blood vessels and takes the back to the heart to get reabsorbed.
