Closed and Open Circulatory System Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. The open circulatory system is common to molluscs and arthropods.

Open Circulatory System:
1. Blood flows in open tissue spaces,
the sinuses, without proper walls.
2. Blood is in direct contact with the
tissue cells.
3. Exchange of materials occurs
directly between blood and tissue
cells.
4. Blood flow is very slow.
5. Blood has a very low pressure.
6. The system is less efficient as the
blood flow cannot be regulated.
Closed Circulatory System:
1. Blood flows in closed tubes, the
blood vessels, with definite walls.
2. Blood does not come in direct
contact with the tissue cells.
3. Exchanged of material between
tissue cells and blood occurs via
tissue fluid.
4. Blood flow is quite rapid
5. Blood has a high pressure
6. The system is more efficient as the
blood flow can be regulated
