Irritable bowel syndromeinflammatory bowel diseasegastrointestinal infections and other poop-related ailments cost Americans billions of dollars annually. But trying to stem these problems was not our main motivation for trying to figure out some of the physics of defecation. It was something else, much more sinister. From personal observation, Sybmolism the lab When parenthood hits, it hits hard. One of us is a working dad who survived Symbolism In Dog Lab learning a new set of skills, one of which was Lwb analysis. Years of diaper changes and then potty training turned me from a poo-analysis novice to a wizened connoisseur. My life passes by in a series of images: hard feces pellets like peas to long feces like a smooth snake to http://pinsoftek.com/wp-content/custom/summer-plan-essay/adeimantus-of-collytus-essays.php puddle of brown water.
But we did think it was worth Symbolism In Dog Lab to understand where all these shapes come from. Having a laboratory to answer questions about the everyday world is one of the distinct pleasures of being a scientist.
As fluid dynamicistswe click forces with colorectal surgeon Daniel Chuand two stalwart undergraduates, Candice Kaminski and Morgan LaMarca, who filmed defecation and hand-picked feces from 34 mammalian species at Zoo Atlanta in order to measure their density and viscosity. The secret to the speed What else did we learn?
Bigger animals have longer feces. And bigger animals also defecate at higher speed. For instance, an elephant defecates at a speed of six centimeters per second, nearly six times as fast as a dog. The speed of defecation for humans is in between: two centimeters per second. Together, this meant that defecation duration is constant across many animal species — around 12 seconds plus or minus 7 seconds — even though the volume varies greatly. Assuming a bell curve distribution, 66 percent of animals take between 5 and 19 seconds to defecate. How Symbolism In Dog Lab Sybolism animals defecate at such high speed? The answer, we found, was in the properties of an ultra-thin layer of mucus lining the walls of the large intestine.
The mucus layer is as thin as human hair, so thin that we could measure it only by weighing feces as the mucus evaporated.
The secret to the speed
Despite being thin, the mucus is very slippery, more than times less viscous than feces. During defecation, feces Symbolism In Dog Lab like a solid plug. One of the big findings of our study was that feces extend halfway up the length of the colon from the rectum. A unified theory of pooping Putting the length of feces together with the properties of mucus, we now have a cohesive physics story for how defecation happens.
Bigger animals have longer feces, but also thicker mucus, enabling them to achieve high speeds with the same pressure. Without this mucus layer, defecation might not be possible. Alterations in mucus can contribute to several ailments, including chronic constipation and even infections by bacteria such as C. Beyond simply following our scientific curiosity, our measurements of feces have also had some practical applications.]
