WATERVASCULAR Meaning and
Definition
-
Watervascular is an adjective that describes a system or structure in certain organisms, typically marine invertebrates such as echinoderms, which functions in locomotion, feeding, and respiration.
In particular, the term refers to the watervascular system, also known as the water vascular system, which is a complex network of fluid-filled canals or tubes that conduct water in these organisms. This system is typically composed of a central ring canal that encircles the mouth, from which radial canals extend outward to various parts of the organism's body. The radial canals are often connected to structures called tube feet, which are small, finger-like projections that extend externally from the body and are used for various functions such as locomotion or capturing prey.
The watervascular system works by utilizing the pressure of water and the contraction of specialized muscles within the canals to extend or retract the tube feet. This mechanism allows the organism to generate movement, perform tasks such as feeding by capturing and manipulating food particles, and assisting in respiration.
Overall, the watervascular system is a defining characteristic of certain marine invertebrates, enabling them to adapt to their aquatic environment and perform essential functions necessary for survival.

Etymology of WATERVASCULAR
The word "watervascular" is derived from two main components: "water" and "vascular".
The term "water" originated from the Old English word "wæter", which was derived from the Proto-Germanic word "watar". This word can be traced back to the Proto-Indo-European root "*wódr̥", meaning "water" or "wet". It is worth noting that water-related words have similar roots in various Indo-European languages.
The term "vascular" comes from the Latin word "vasculum", which means "a small vessel". It is a diminutive form of "vas", meaning "vessel" or "container". This Latin word is derived from the Proto-Italic word "*wasko", which is ultimately connected to the Proto-Indo-European root "*wes-", meaning "to dwell" or "stay in place".
