In addition to the heart, digestive system, and blood vessels, the uterus actually contracts, too! The wave-like motions of uterine peristalsis(or UP for short) accompany the other organs mentioned above as organs that contract. The uterine contractions usually flow downwards during the menses phase of the menstrual cycle, which is when menstruation occurs. This helps to push menstrual blood out of our systems.
Below, I’ve linked a video that my sister, Emily, made regarding UP if you want to learn more about it. Enjoy!
Extra little bits: Now, what if UP waves are going up during the menses phase?? 🤔 Good question! Sometimes, when UP is going upwards, it can tell us that the patient may have endometriosis. Endometriosis is closely related to deregulation in the menstrual cycle; this disease can result in severe pain and the formation of lesions in places they shouldn’t be. (Like outside of the uterus) Feel free to check out our article on endometriosis for more information.
