卵巣

1. Origins, structure, and basic meaning

• Structure: 卵巣 is read as らんそう and is an anatomical noun for an ovary, the egg-producing reproductive organ in humans and other animals.
• Basic usage: Instructional material uses 卵巣の位置 and 卵巣の構造 to link the organ with its location or structure.

2. Common pitfalls and similar expressions

• Anatomical term in instructional material
  • Both examples concern diagrams and textbook explanation, not diagnosis of a real person.
• Singular and plural translation
  • Japanese 卵巣 can name the organ category without overt number, so English ovary or ovaries depends on what the diagram presents.
