The Clam
The clam has an open circulatory system which means that
blood is pumped out of the heart and goes through a few large vessels
to the tissues where it exits the arteries and enters large spaces where it
passes over the cells of the various organs. It then collects into large
internal spaces called lacunae from which it passes through the kidney
and gills, then returning to the heart in the end.

The Oyster
The Oyster has a similar circulatory system as the clam. This means
that the oyster also has an open circulatory system. If you weren't paying
attention before it goes like this: blood is pumped out of the heart and goes through a few large
vessels to the tissues where it exits the arteries and enters
large spaces where it passes over the cells of the various organs.
It then collects into large internal spaces called lacunae from which it passes
through the kidney and gills, then returning to the heart in the end.

The Snail
The snai's circulatory differs from other species' circulatory system.
Snails have a space in the tissue where the blood is transported to
All snails lack capillaries which connect an artery to a vein so
their blood flows directly into the tissues between the ending of an artery and
the beginning of a vein.

Circulatory System of The Snail
This is a picture of the snail's circulatory system, however it's not all of it.
Circulatory System of The Oyster and The Clam
This picture shows the whole circulatory system of the two mollusk examples.
