The term "arsenoblast" refers to a type of cell that is responsible for producing red blood cells in the bone marrow. Its spelling can be explained using the International Phonetic Alphabet (IPA) as /ɑːsənəʊblæst/. The first syllable (/ɑː/) is pronounced like the "ar" in "car", and the second syllable (/sənəʊ/) is pronounced like "senna" with an "o" sound after it. The final syllable (/blæst/) is pronounced like "blast" with a short "a" sound. Overall, the word's spelling reflects its Greek origin and the specific sounds used in English pronunciation.
