The Vietnamese word "bộ lòng" refers to the internal organs of animals, particularly when discussing the edible parts. It is commonly used in the context of food, especially in Vietnamese cuisine, where various animal parts are prepared and served in dishes.
While "bộ lòng" primarily refers to the entrails of animals in culinary contexts, in a broader sense, it can refer to the concept of using all parts of an animal in cooking, which is a practice that promotes sustainability and respect for the food source.
