Etymology
The adjective 'tubal' is a modern scientific formation, directly constructed from the English noun 'tube'. The root 'tube' itself entered English from French in the 17th century, tracing back to the Latin 'tuba', which originally denoted a straight trumpet or war-horn, a meaning derived from its hollow, cylindrical shape. The Latin suffix '-alis', signifying 'relating to', was adopted into English as '-al' to form adjectives from nouns. Thus, 'tubal' logically builds on the core concept of a hollow cylindrical structure, applying it specifically in anatomical contexts to describe anything pertaining to such a tube, most notably the fallopian tubes in human biology.
Analysis
tub (from Latin 'tuba', meaning 'tube' or 'trumpet'); al (from Latin '-alis', an adjective-forming suffix meaning 'pertaining to').
