Blood Cells:
* Red Blood Cells (Erythrocytes): Carry oxygen throughout the body.
* White Blood Cells (Leukocytes): Fight infections and diseases.
* Platelets (Thrombocytes): Help with blood clotting.
Immune System Cells:
* B cells: Produce antibodies to fight infections.
* T cells: Attack infected cells and regulate the immune response.
Other Cell Types:
* Fat Cells (Adipocytes): Store energy and provide insulation.
* Stromal Cells: Provide structure and support for bone marrow.
Important Note: Not all bone marrow is the same. Red bone marrow is where blood cells are made, while yellow bone marrow is mostly fat and can be converted back to red marrow if needed.
