Which of the following needles has the widest lumen?

lumen
because lumen carries biochemical processes for the cells.
Lumen and candlepower are not the same thing. Lumen measure the of light surrounds, like you would light a room with a lamp. Candlepower measures the light in a beam, like a flashlight beam. With a few assumptions you can convert lumen to candlepower. With these assumptions 360 lumen would be 28.6 candlepower.
The lumen is the size of the inside of the blood vessel. The type of blood vessel that has a lumen approximately the same diameter as a single red blood cell is a capillary.
The digestive system features lumen in the gastrointestinal tract. Absorption is the passage of digested end products from the lumen of the GI tract through the mucosal cells into the blood or lymph.
Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.
hemolysis occurs due to the needle lumen being too small (ie a larger gauge). The larger the needle (or lower gauge), the less likely it will damage the cells and cause hemolysis. Avoid 25g and smaller needles.

the gauge is the measurement of how big around the stud or needle is
The 21 gauge is a smaller needle.
Yes, the larger the gauge the smaller the needle size.
Yes, a 30 gauge needle would be tiny, while an 8 guage needle is huge.
A round gauge with a needle to point at the measure.
Yes it is smaller in terms of diameter. Explanation: 25 gauge refers to a needle having an inner diameter of 1/25" (1/25 inches) and 22 gauge refers to a needle having an inner diameter of 1/22" (1/22 inches). Thus the 25 gauge needle has a smaller inner diameter than a 22 gauge needle.
