PLECTONEPHRIDIA Meaning and
Definition
-
Plectonephridia is a term used in biology to describe a type of excretory organ found in certain invertebrate organisms, particularly in annelids, such as earthworms. It refers to a complex network of tubular structures called nephridia that perform the function of excretion and osmoregulation in these organisms.
Plectonephridia are composed of numerous small units called nephridiopores, which are scattered along the body segments of the organism. Each nephridiopore leads to a coiled tubule inside the body, which further connects to a larger duct that ultimately leads to an opening on the body surface.
The main function of plectonephridia is to filter metabolic wastes, such as ammonia and urea, as well as excess water and ions from the body fluids of annelids. These waste products and excess fluids are transported through the tubular network of plectonephridia and are finally released outside the organism's body.
In addition to waste elimination, plectonephridia also play a role in maintaining the internal balance of fluids and ions within the organism. They help regulate osmotic pressure by selectively reabsorbing certain molecules and ions from the filtered fluid and excreting others.
Overall, plectonephridia are essential excretory structures in annelids, facilitating waste removal and osmoregulation to ensure proper physiological functioning of these organisms.

Etymology of PLECTONEPHRIDIA
The word "plectonephridia" has a Greek origin. It is derived from two Greek roots: "plekto" meaning "twisted" and "nephros" meaning "kidney". In zoology, plectonephridia refers to a type of excretory system found in certain invertebrates, particularly some worms and flatworms.
