The dia of cappillary is called bore. normally it is measured by Inches. for example 0.50",0.55". ( lesser than this sizes also available in market.)
The dobhoff tube goes from nose to small intestine duodenum. The nasogastric (NG) tube goes from nose to stomach. More in-depth answer: A dobhoff tube is a small-bore feeding tube that runs from one of the nares to the stomach, then to the first part of the small intestine (duodenum). It can be advanced blindly 10 more cm to see if it can be threaded through the pyloric valve, but if it keeps coiling in the stomach, most doctors will order to place it the rest of the way under fluoroscopy. It can also be bridled in for extra security. This is mainly a feeding tube and can stay in for weeks to a few months. An NG tube is a large-bore tube that is used for many different reasons, including decompressing the stomach for surgery and to prevent nausea/vomiting. It is NOT used for tube feedings. Usually this tube does not stay in for very long. (This answer is based on my knowledge drawn from being a critical care RN.)
A sample tube, culture tube, sometimes a boiling tube.
EDTA tube or lavender tube
A culture tube or sample tube.

A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
The Bore of an engine is the tube that the piston goes up and down in.
At cappillary bed
Small bore ngt (Nasogastric tube) is a tube inserted through the nostril (nare) that is flexible and soft (8 French-12 French diameter) used for feedings, and kept in place longer than a large bore ngt. Large bore ngt (Nasogastric tube) is a tube inserted through the nostril (nare) that is less flexible and more firm (14 French diameter or larger) used for feedings, to give medications, and for gastric decompression. It is kept in place for a shorter period than a small bore ngt.
Not unless you have to change the choke tube.
Cappillaries are narrow tubes of the artery which carry blood.

It would have to be a pump or semi-auto with an extended magazine tube.
Upper receiver
A boroscope is an instrument for looking down a narrow tube or bore such as down a gun barrel. The word comes from a combination of 'bore' and 'scope' because of this primary initial use.
The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.
A borescope is an optical device where the user looks into an eyepiece attached to a flexible tube and can see from the end of the tube. The tube can be bent and positioned, allowing the user to inspect areas that are otherwise out of reach.
