blood
'das Blut' and 'das Plasma' both belong to the topic of the body and medicine. 'Blut' means the whole red fluid that flows through the body. 'Plasma' means only the liquid part of blood without blood cells. Learners may confuse the words because plasma is a component of blood. In everyday language, you usually say 'Blut', for example when talking about an injury or a blood sample. 'Plasma' fits better in medical or biological contexts.
