peristaltickými

Peristaltic is a term derived from peristalsis, a physiological process involving coordinated muscular contractions and relaxations that propel contents through a tube-like organ. In a biological context, peristaltic movements are characteristic of the digestive tract, where they move food from the esophagus to the stomach, churn it within the stomach, and propel it through the intestines. This wave-like motion ensures efficient digestion and absorption of nutrients. Beyond the digestive system, peristalsis is also observed in other hollow organs, such as the fallopian tubes to move eggs towards the uterus and the ureters to transport urine from the kidneys to the bladder. The rhythmic contractions are controlled by the autonomic nervous system and intrinsic smooth muscle activity.

The principle of peristalsis has been applied in engineering, most notably in the development of peristaltic pumps. These pumps work by compressing a flexible tube in a sequential manner, creating a vacuum that draws fluid in and then expelling it forward. This method of fluid transfer is advantageous because the fluid only comes into contact with the inner surface of the tube, minimizing contamination and preventing damage to shear-sensitive liquids. Peristaltic pumps are widely used in medical applications, such as intravenous fluid delivery and dialysis, as well as in laboratory settings for precise dispensing and in industrial processes for handling chemicals and food products. The controlled nature of the pumping action makes them suitable for applications requiring gentle and accurate fluid handling.
