Final answer:
Yes, hematuria is the presence of intact red blood cells in urine, and it is a true statement. It is a condition that can indicate various underlying health issues. Hemoglobinuria, which is different, involves only hemoglobin without intact red cells.
Step-by-step explanation:
The statement "Hematuria is the presence of intact red blood cells in urine." is true. Hematuria is indeed a condition characterized by blood in the urine and can be a sign of various medical conditions, such as nephritis, kidney stones, trauma, or urinary tract infections. Hemoglobinuria, on the other hand, involves the presence of hemoglobin in the urine but not intact red blood cells, and can occur in diseases such as malaria and typhoid.
Formation of blood cells, or hematopoiesis, is a separate but related process in which blood cells differentiate from pluripotent hematopoietic stem cells. Conditions that affect the blood cells can indirectly lead to hematuria, as well as affect overall health. For example, disorders like myelofibrosis and thalassemia influence the formation and function of different blood cells, leading to various complications.
