輸血

1. Origins, structure, and basic meaning

• Structure: The written form is 輸血, read ゆけつ. Elements for transfer and blood combine to name the medical procedure of supplying blood to a patient.
• Basic usage: 輸血の目的 treats the procedure as a subject of study, while 輸血を受ける states that a patient received it.

2. Common pitfalls and similar expressions

• Learning the concept
  • The sentence concerns general principles—purpose and blood-type relationships—rather than one treatment event. Example: 授業で輸血の目的と血液型の関係を学んだ。 — In class, we learned about the purpose of blood transfusions and how blood type relates to them.
• Receiving the procedure
  • With the patient as subject, the construction says that the patient received the transfusion. Example: 物語の患者は手術中に輸血を受けた。 — The patient in the story received a blood transfusion during surgery.
