The muscularis layer of the stomach is thickest and maximum peristalsis occurs here. After short intervals, the pyloric sphincter keeps on opening and closing so the chyme is fed into the intestine in installments. Small intestine
Once processed and digested by the stomach, the semifluid chyme is passed through the pyloric sphincter into the small intestine. Once past the stomach, a typical peristaltic wave lasts only a few seconds, traveling at only a few centimeters per second. Its primary purpose is to mix the chyme in the intestine rather than to move it forward in the intestine. Through this process of mixing and continued digestion and absorption of nutrients, the chyme gradually works its way through the small intestine to the large intestine.In contrast to peristalsis, segmentation contractions result in that churning and mixing without pushing materials further down the digestive tract. Large intestine
Although the large intestine has peristalsis of the type that the small intestine uses, it is not the primary propulsion. Instead, general contractions called mass action contractions occur one to three times per day in the large intestine, propelling the chyme (now feces) toward the rectum. Mass movements often tend to be triggered by meals, as the presence of chyme in the stomach and duodenum prompts them (gastrocolic reflex). Minimum peristalsis is found in the rectum part of the large intestine as a result of the thinnest muscularis layer. Lymph
The human lymphatic system has no central pump.
A myoma is a type of tumor that involves muscle cells. There are two main types of myoma: 

Leiomyomas which occur in smooth muscle. They most commonly occur as uterine fibroids, but may also form in other locations. Rhabdomyomas which occur in striated muscle. They are rare tumors, occur in childhood and often become malignant.Whether or not angiomyomas are a type of leiomyoma or a separate entity is disputed as of 2014.Myomas are benign tumors of the uterus that can affect the fertility of a woman depending mainly on three factors:

Size (cut off value 4-5 cm)
Number
Location (they can be intramural, subserous or submucous). Submucous ones are worst from a fertility point of view, while subserous are less dangerous.Some of the most common symptoms are: abundant menstrual bleeding, longer menstrual periods, pelvic pressure, constipation, a need to urinate continuously.
