Red blood cells are produced by stem cells in the Blank______.Multiple choice question.heartbone marrowlarge intestinekidneys

Break Down the Problem

1. Identify the key terms in the question: "Red blood cells," "stem cells," and the location where red blood cells are produced.
2. Analyze the answer choices: heart, bone marrow, large intestine, kidneys.

Relevant Concepts

3. Understand that red blood cells (erythrocytes) are produced in a specific location in the body through a process called erythropoiesis, which involves stem cells.

Analysis and Detail

4. Evaluate the function of each option:
   • Heart: Primarily involved in pumping blood, not producing blood cells.
   • Bone Marrow: The primary site for hematopoiesis, where all blood cells (including red blood cells) are produced from stem cells.
   • Large Intestine: Responsible for absorbing nutrients and water, not related to blood cell production.
   • Kidneys: They filter blood and produce urine, but they do not produce red blood cells.

Verify and Summarize

5. After reviewing the functions of each option, it is clear that the bone marrow is the correct answer, as it is the primary site of red blood cell production.

Final Answer

Bone Marrow
