Muscle contractions then push the stool toward the rectum, and, by the time the stool reaches the rectum, most of the water has been absorbed, making the stool solid. When the colon's muscle contractions are slow or sluggish, the stool moves through the colon too slowly, resulting in too much water being absorbed.
The microparticulate allograft is a mixture of mineralized cortical bone particles of a standard combination of sizes between 100 and than 250 microns. This provides an optimal scaffold for delivering osteoinductive growth factors. This preparation has an appropriate 3-dimensional (3-D) structure
Micrometre is 1 millionth of a meter, 1 thousandths of a milimeter (mm), or 1 x 10-6 meters. To give you the idea of how small a micro metre is, a human hair is about 100 Âµm, wide, and a red blood cell would be around 8 Âµm wide, the typical size of an animal cell would be from 10 - 100 Âµm.NSWER Generally in Science, you would use the Metric system of measurement. Therefore, when talking about cells and microscopic organisms, you would be measuring using MICROMETRE (abbreviated: Âµ --micron) or stated as: Âµm (micro metre).
