Step-by-step explanation:
Sediments in the urine consisting of clumps of blood cells, epithelial cells, and crystals are called casts.
Cast formation in urine occurs when substances in urine, such as red blood cells, white blood cells, or crystals, clump together and form solid deposits. These deposits can vary in composition and appearance depending on the specific substances present in the urine.
In the case of clumps of blood cells, epithelial cells, and crystals, they are referred to as casts. These casts can provide important diagnostic information about kidney function and potential underlying conditions or diseases.
