Circulatory system of Sea stars Sea stars do not pump blood through their bodies. They use a seawater and a complex water vascular system for things to move. Its tube are vital in the circulatory system which are also used in movement. On its underside, their have hundreds of tube feet. ...

1. 1. Osmotic measurements were made on the perivisceral coelomic and water vascular fluids of 4 species of northwest Pacific starfish and their stable sea-water media. 2. 2. Mean levels of both fluids were hyperosmotic in every species, often at statistically significant levels. 3. 3. For ...

In addition, as well as incorporating the radial nerve cord, which is continuous with the epidermis [23], the ambulacral body wall houses a number of longitudinal vessels and coelomic compartments, including the radial water vascular canal (which is a component of the hydraulic system of the ...
