What happens to your sphincter when you poop?
As a financial professional with a keen interest in the intricacies of the human body, I'm curious to delve into a rather unconventional topic: the function of the sphincter muscle during bowel movements. Could you elaborate on the physiological process that occurs when one engages in the act of defecation? Specifically, I'm interested in how the sphincter relaxes to allow the passage of waste, and if there are any key factors that affect its performance. Furthermore, are there any health implications associated with improper sphincter function during this process? I'd appreciate a concise yet thorough explanation of this fascinating bodily function.
