This is known as a long vowel sound, because it says the ânameâ of the letter. The same goes for the other vowels. A short vowel sound is a vowel sound that does not follow this rule. When reading a word that uses a short vowel sound, will say the sound that the letter can make that is not its actual name. So in the case of âA,â the word âmainâ might have a long âAâ sound because we pronounce the âAâ as /Ä/, whereas the word âmanâ has a short vowel sound.
Gill arches supporting the gills in a pike. Branchial arches, or gill arches, are a series of bony loops present in fish, which support the gills. As gills are the primitive condition of vertebrates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arches varies between taxa.
Gill arches bearing gills in a pike. Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of cloth and fabric structures called filaments.These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia.ost fish exchange gases using gills on either side of the pharynx (throat).
