A study tracked the steps of 1,136 adults around the United States who wore pedometers for two days in 2003. The results were compared to similar pedometer studies in Switzerland, Australia and Japan.The data collected showed that Americans, on average, took 5,117 steps a day, far short of the averages in western Australia (9,695 steps), Switzerland (9,650 steps) and Japan (7,168 steps).Written 17 Nov, 2014 â¢ View Upvotes. study tracked the steps of 1,136 adults around the United States who wore pedometers for two days in 2003.

pseudocoelomate. (soÍo'dÅsÄ`lÉmÄt') , any of a group of invertebrates with a three-layered body that has a fluid-filled body cavity (pseudocoelom) between the endoderm and the mesoderm (the innermost and middle tissue layers).
A true coelom is formed within the mesoderm layer; thus, the true coelom is entirely lined with mesoderm. Both the gut and the body wall have mesodermal components. A pseudocoelom is not fully lined by mesoderm; in pseudocoelomates the mesoderm is only associated with the outer body wall, and not with the gut.Some bilaterally symmetrical organisms lack a body cavity; these are called acoelomates.evelopment of Body Cavity. All of the bilaterally symmetrical eumetazoans also have three germ layers: ectoderm, mesoderm and endoderm. The addition of mesoderm is very important; it is this embryonic tissue which gives rise to the muscular system, as well as many other adult structures.
