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
Paramecium caudatum is 120â330 micrometres long (usually 200â300 micrometres). The cell body is roughly cigar-shaped, rounded at the front, tapering at the posterior to a blunt point. The pellicle is uniformly covered with cilia, and has a long oral groove, leading to deeply embedded oral cavity, lined with cilia.
