Bone Marrow:
* Red blood cells (erythrocytes): Responsible for carrying oxygen throughout the body.
* White blood cells (leukocytes): Crucial for immune defense, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
* Platelets (thrombocytes): Important for blood clotting.
Spleen:
* Filters blood: Removes old or damaged red blood cells, white blood cells, and platelets.
* Stores red blood cells: Releases them into circulation when needed.
* Lymphocyte development: Houses lymphocytes, including B cells and T cells, which are essential for immune responses.
In summary:
* Bone marrow is the primary site of hematopoiesis, the process of blood cell formation, producing all three types of blood cells.
* Spleen plays a supportive role, primarily filtering the blood, storing red blood cells, and contributing to lymphocyte development.
It's important to note that while bone marrow is the primary site for blood cell production, the spleen also contributes to some aspects of blood cell development and function.
