Defecation is normally assisted by taking a deep breath and trying to expel this air against a closed glottis (Valsalva maneuver). This contraction of expiratory chest muscles, diaphragm, abdominal wall muscles, and pelvic diaphragm exerts pressure on the digestive tract.
Flocculation is one step in the water and wastewater treatment process. In a flocculation tank, the water is stirred or otherwise moved around so that the particles move around, bump into other particles, and stick to one another.he limit flocculation is the amount of an antibody (measured in  international units) which equilibrates the antigen present such  that the antigen-antibody complexes preci â¦ pitate (flocculate :  asexual aggregation of microorganisms.).
