explanation: "arterial blood vessels", "venous blood vessels" and "capillaries" are  all types of blood vessels. "prose", "poetry" and "fiction" are all literary genres, but they are not the whole range of literary subjects. "historical films", "war films" and "science fiction films" are all films, but they are not the only types of themes of film. "dormant volcanoes", "extinct volcanoes" and "active volcanoes"  constitute all types of volcanoes. "sunny days", "rainy days" and "snow days" belong to a juxtaposition, but the three are not the only weather phenomena.
