OPEN & CLOSED CIRCULATORY SYSTEMS
OPEN: Circulatory fluid covers organs directly and has same circulatory fluid
CLOSED: Blood is only in the vessels and is different from the interstitial fluid

Mammalian CirculationTHE HEART The Circulatory
System
Blood from right ventricle goes to the lungs for oxygen. Oxygenated blood goes to the left ventricle to pump blood throughout the body.
