The word is lumen. It means the interior of a hollow tubular structure such as the intestine.
No, the sun is not hollow. It is a massive sphere composed primarily of hydrogen and helium gas undergoing nuclear fusion at its core. Its density and structure are well understood by scientists through various observations and measurements.
this structre is not a frame structure because it is not hollow i think it is a combination structure because it is solid but has hollow parts!!! anyway look it up some where else this one sucks!!!
lumen
A hollow bone structure (skeleton).
Microtubules are composed of tubulin protein subunits that polymerize into long, hollow tubes. They are essential for cell structure, intracellular transport, and cell division. Microtubules dynamically assemble and disassemble, allowing cells to quickly reorganize their structure as needed.
an igloo is a shell structure since it is not filled it is only a shell
the lumen
It's a shell. And because it is hallow Inside. A shell structure is a Structure that is strong hollow And light in size.
The bladder is the hollow holding structure for urine in the human body. It is a muscular organ located in the pelvis that expands as urine is stored and contracts to release urine through the urethra.
Bamboo is hollow because it helps the plant to be strong and flexible while also being lightweight. The hollow structure allows for efficient transport of water and nutrients throughout the plant.
Robert Hooke described the microscopic structure of cork as resembling a honeycomb in his 1665 work "Micrographia." He observed that the cork was composed of tiny, hollow compartments, which he referred to as "cells." This observation laid the groundwork for the cell theory, highlighting the basic structural unit of life.
