Translation guide
In English, 'capillary' refers to the smallest blood vessels in the body. In Japanese, the most common and natural term is 毛細血管 (もうさいけっかん). The shorter form 毛細管 (もうさいかん) is used in technical or physics contexts (e.g., capillary tubes).
The smallest blood vessels connecting arteries and veins.
Standard medical and everyday term for blood capillaries.
毛細血管は、動脈と静脈をつなぐ非常に細い血管です。
Capillaries are very thin blood vessels that connect arteries and veins.
毛細血管の壁は薄く、物質交換が行われます。
The walls of capillaries are thin, and substance exchange takes place.
Can refer to blood capillaries, but more commonly used for capillary tubes in physics or engineering. In medical contexts, 毛細血管 is preferred.
毛細管現象により、水が細い管の中を上昇する。
Due to capillary action, water rises in a thin tube.
A very thin tube, often used in scientific instruments or referring to capillary action.
The standard term for a capillary tube in physics and engineering.
この実験では、毛細管を使って液体の表面張力を測定します。
In this experiment, we measure the surface tension of the liquid using a capillary tube.
Loanword from English, used in some technical contexts, but 毛細管 is more common.
毛細血管 specifically means blood capillaries. 毛細管 can mean blood capillaries but is more often used for non-biological capillary tubes. In medical contexts, always use 毛細血管 to avoid ambiguity.
キャピラリー電気泳動は、DNA分析に用いられる。
