Spectrin and actin

Cell body spherical, 10-12 microns

nuclear

(Nuclear shift to the left: severe bacterial infection, nuclear shift to the right: bone marrow hematopoietic dysfunction)

The cytoplasm is very light pink and contains granules.

Strong chemotaxis, phagocytosis of bacteria and foreign bodies

After being swallowed in large quantities, they die and turn into pus cells.

Spherical, 10-15 microns

The nucleus is often divided into two lobes

Bright red eosinophilic granules (specialized lysosomes)

Deformation movement (chemotaxis)

Anti-allergic reactions, anti-parasitic

Spherical, 10-12 microns

The nucleus is lobed or S-shaped or irregular

Blue-purple basophilic granules (secretory granules)

Synthesize and secrete leukotrienes

Involved in allergic reactions (same as mast cells)

small lymphocytes

Lymphocytes

large lymphocytes

Ribosomes, lysosomes, mitochondria, Golgi apparatus, rough endoplasmic reticulum

There are mainly small lymphocytes in the blood, some medium lymphocytes, and large lymphocytes are present in lymphoid tissues.

microfilaments microtubules

Special granules (a granules), dense granules, a small number of lysosomes, open tubules, dense tubules
