검증된 단계별 안내1
Understand the components of blood: blood consists of formed elements (such as red blood cells, white blood cells, and platelets) suspended in plasma, which is a liquid matrix.
Recall the definitions of mixture types: a pure substance contains only one type of element or compound; a homogeneous mixture (true solution) has uniform composition throughout; a heterogeneous mixture has visibly different components or phases; a colloid contains particles that are intermediate in size and do not settle out.
Analyze blood's characteristics: since blood contains cells suspended in plasma, these formed elements can settle out if left undisturbed, indicating it is not a true solution or pure substance.
Recognize that blood is a suspension because the formed elements are suspended in plasma and can be separated by centrifugation, which fits the definition of a heterogeneous mixture.
Conclude that blood is best classified as a heterogeneous mixture (a suspension of formed elements in plasma) based on its composition and behavior.
