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).
Schematic diagrams of the bodies of animals with coeloms, with pseudocoeloms, or without body cavities. In humans all but the cranial cavity develop from the coelom (pronounced SEE-lum). A coelom is a cavity that is entirely enclosed within cells derived from the middle layer of embryonic tissue. A few groups of animals, such as roundworms (Nematoda), have a body cavity that is only partly enclosed by tissue from the middle layer. Such a body cavity is called a pseudocoelom (pronounced SOO-doe-SEE-lum). In a few other groups, such as flatworms (Platyhelminthes), there is no body cavity.
