How to Say "Blood Vessel" in Japanese

血管

kekkan[ke̞k̚kã̠ɴ]

The English phrase "blood vessel" is 血管 (kekkan) in Japanese.

血管 is a noun used to refer to a component of the circulatory system that carries blood.

Meaning: component of the circulatory system that carries blood (noun)

What does it mean word for word?

The word is composed of the kanji 血 (blood) and 管 (tube/pipe).

The romanization is kekkan.

Japanese speakers use the word 脈 (pulse/vessel) to describe 'connections' between people, such as 脈がある meaning there is a 'chance' or 'connection' in a romantic sense.
In Japanese pop culture and anime, the phrase 血管 is often used metaphorically when a character is so angry that a vein 'pops' or 'bulges' on their forehead, often depicted as a cross-shaped symbol.
The kanji 管 in 血管 is also used in the word 管轄, which means 'jurisdiction' or 'control'. This connects the physical idea of a pipe to the abstract idea of managing a specific area.
