Muscles that encircle tubes and act as circular valves are called?
Sphincter muscles. They are smooth muscles found in various parts of the body, such as the digestive system and urinary tract, and control the opening and closing of tubes or openings.

the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.

What are the different types of valves used in bike inner tubes?
The different types of valves used in bike inner tubes are Presta valves and Schrader valves. Presta valves are slender and have a lock nut at the top, while Schrader valves are wider and similar to those found on car tires.
What are the various parts of an trumpet?
mouthpiece, valves, spit valves, slides, tubes and bell
What are the different types of valves used in bicycle inner tubes?
The different types of valves used in bicycle inner tubes are Presta valves and Schrader valves. Presta valves are thinner and require a special pump, while Schrader valves are similar to those found on car tires and can be inflated with a regular pump.
What are the Components of first generation of computers?
vaccum tubes and valves.
What technology was the first step towards electronic miniaturization?
The transistor was the invention that allowed electronics to move away from the use of vacuum tubes (also called valves).
Uterine tubes are also called what?
Fallopian tubes
What is call The tubes that bring water into mollusks?
These are called valves- some molluscs have two and are called BIVALVES, whilst others have three and are called TRIVALVES. The latter are held to be higher up the evolutionary scale. The bivalves are the clams, mussels, oysters and scallops. The adults all have two hinged shells (valves). Some of these animals circulate water carrying the microorganisms that they eat and oxygen for respiration through tubes called "siphons" that they can extend from between the shells on the anterior end so they can stay safely hidden in the mud or sand.
