@theanatomylab7: Ever wondered how your body decides whether to hold in a fart? 😳💨 Your body can tell when gas needs to come out. 💨 Pressure builds inside the rectum, but your external anal sphincter and pelvic floor muscles can voluntarily contract to help you hold it in. This is a fascinating example of how your brain and muscles work together to control bowel function. 🧠🫁 #HumanAnatomy #DigestiveSystem #BodyScience #AnatomyFacts #MedicalAnimation
