MESONEPHRIDIUM Meaning and
Definition
-
Mesonephridium is a term used in biology to describe a structure found in certain invertebrates, particularly segmented worms known as annelids. It is part of the excretory system responsible for removing metabolic wastes and regulating the osmotic balance in these organisms.
The mesonephridium is a tubular, ciliated organ that spans segments of the body, typically from the coelomic cavity to the exterior. It acts as a functional unit, consisting of a funnel-like structure called a nephrostome, a long tubule, and a nephridiopore located on the body surface. The cilia lining the mesonephridium play a crucial role in the movement of fluids and waste products through the system.
The mesonephridium filters the coelomic fluid, extracting waste materials such as nitrogenous compounds, excess ions, and water. These waste products are then transported through the tubules via active transport or reabsorption processes. Ultimately, the filtered fluid is excreted from the organism through the nephridiopore.
The mesonephridium serves as an important organ for maintaining osmotic balance, eliminating harmful metabolic wastes, and regulating the internal environment of the organism. However, it is important to note that the complexity and structure of the mesonephridium can vary across different annelids and invertebrate species, suggesting some variability in its function and morphology.

Etymology of MESONEPHRIDIUM
The word "mesonephridium" is derived from two root words: "meso-" and "nephridium".
1. "Meso-" comes from the Greek word "mesos", meaning "middle" or "intermediate".
2. "Nephridium" is derived from the Greek word "nephros", which translates to "kidney" or "the organ that filters blood and produces urine".
Therefore, "mesonephridium" combines these roots to refer to a structure that lies intermediate to or between kidneys. In biology, it specifically refers to an excretory organ found in some invertebrates.
