Main Translations

English: Capillary

Thai: หลอดเลือดฝอย (Lod Leuat Foi)

Phonetic: [lawt lə̀ʔwàt fɔ̀j]

Detailed Explanation: The term "capillary" primarily refers to a very thin tube or vessel, especially in biological contexts, such as the smallest blood vessels in the human body that facilitate the exchange of oxygen, nutrients, and waste between blood and tissues. In Thai, "หลอดเลือดฝอย" is the most common translation and carries a neutral, scientific connotation. It is widely used in medical and educational scenarios, emphasizing precision and technical detail. For instance, in healthcare discussions, it evokes a sense of microscopic scale and vital physiological processes, highlighting the word's semantic nuance of fragility and essential function in circulation.

Thai: หลอดขน (Lod Khon)

Phonetic: [lawt khɔ̌n]

Detailed Explanation: This secondary translation is more physics-oriented, referring to a thin tube or capillary tube used in experiments involving fluid dynamics, such as capillary action (the ability of a liquid to flow in narrow spaces against gravity). In Thai, "หลอดขน" implies a hair-like structure and is less emotionally charged, focusing on practical applications in science and engineering. Its usage scenarios often involve laboratory settings or technical explanations, where the nuance leans toward mechanical properties rather than biological ones, making it a versatile term for non-medical contexts.
