Peristaltic Meaning: Definition, Examples, and Translations
๐ฝ๏ธ
peristaltic
[หperษหstal(t)ik ]
Definition
biological process
Peristaltic refers to the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements that push the contents of the canal forward. This process is essential for the digestion of food and movement of waste through the digestive tract.
Synonyms
muscular contraction, wave-like.
Examples of usage
- Peristaltic movements help in digestion.
- The peristaltic action moves food along the esophagus.
- In a healthy digestive system, peristaltic contractions occur regularly.

Interesting Facts
Science
- Peristaltic movements are crucial for digestion, helping to advance food through the digestive tract.
- These movements occur in the esophagus, stomach, and intestines, ensuring nutrients are absorbed efficiently.
- The process also includes rhythmic contractions that mix food with digestive juices for better breakdown.
Medicine
- Certain conditions, like gastroparesis, occur when the normal peristaltic action is delayed, leading to digestive issues.
- Medications can affect peristaltic movement, either enhancing or inhibiting the process.
- Understanding these movements helps doctors diagnose and treat related gastrointestinal disorders.
Technology
- Peristaltic pumps mimic this natural movement to transport liquids in various industries, like pharmaceuticals and food processing.
- These pumps are often used in laboratory settings to ensure precise fluid delivery without contamination.
- Their design allows for smooth, controlled flow, making them ideal for sensitive materials.
Animal Physiology
- Many animals, including humans, rely on peristaltic movement for digestion, but different species have unique variations.
- In some marine organisms, a similar movement helps move water and nutrients through their bodies.
- The efficiency of this movement can influence an animal's feeding and growth rate.
Origin of 'peristaltic'
Main points about word origin
- The term comes from the Greek word 'peristaltikos', which means 'to push around'.
- It combines 'peri-', meaning around, and 'staltos', meaning constricted or contracted.
- The usage of the term in the medical field first appeared in the early 19th century.
The term 'peristaltic' originates from the Greek word 'peristaltikos', which relates to 'peristalsis'. The prefix 'peri-' means 'around' or 'surrounding', while 'stalsis' is derived from 'stallein', meaning 'to constrict'. The word is rooted in the scientific study of human physiology and gastrointestinal function, describing a fundamental mechanism that allows organisms to ingest food, absorb nutrients, and eliminate waste. The first known use of 'peristalsis' in this context appeared in the early 19th century, corresponding with advancements in medical and biological understanding, particularly relating to the workings of the digestive system.
