Study Notes
Formed Elements of Blood
- Consist of cells and cell fragments
- Include erythrocytes, leukocytes, and thrombocytes
Erythrocytes (Red Blood Cells)
- Most common of the formed elements
- Function: undefined in the provided text
Leukocytes
- Least common of the formed elements
- Types:
- Monocytes
- Lymphocytes
- Basophils
- Abundance: not specified in the provided text
Monocytes
- Large, irregularly-shaped cells
- Irregularly-shaped nucleus (not segmented or multi-lobed)
- Light-colored cytoplasm, granules not visible
- Some have vacuoles
- Phagocytic when transformed into macrophages
Lymphocytes
- Usually smaller, very round cells
- Darker nucleus occupying most of the cell
- Very little cytoplasm
Basophils
- Large cells filled with deep-purple granules
