Blood is composed of plasma and blood cells. (1) Plasma Plasma is equivalent to the intercellular substance of connective tissue. It is a light yellow translucent liquid. In addition to containing a large amount of water, it also contains inorganic salts, fibrinogen, albumin, globulin, enzymes, hormones, and various nutrients. Substances, metabolites, etc.

blood
3. Red blood cells
1. Shape: double concave disc shape,
2. Mature red blood cells have no nucleus and the cytoplasm is filled with hemoglobin.
3. Function: Combine and transport oxygen and carbon dioxide
4. Immature red blood cells: reticulocytes
4. The occurrence of bone marrow and blood cells
1. Red bone marrow: the main structural component is hematopoietic tissue
2. Yellow bone marrow: The main structural component is adipose tissue and has hematopoietic potential.
3. Hematopoietic stem cells (multifunctional stem cells)
a. Concept: primitive cells of various blood cells
b. Features:
i. Strong proliferation potential
ii. Multi-directional differentiation ability
iii. Ability to self-replicate
hematopoietic progenitor cells
2. White blood cells
1. Classification
a. {█(Agranulocyte @Agranulocyte)┤
2. Neutrophils
a. Shape: The nucleus is rod-shaped (immature cells); lobed (mature white blood cells)
b. Left shift of nucleus (rod nucleus) - severe bacterial infection
Rightward nuclear shift (aging lobulation) - bone marrow hematopoietic dysfunction
c. Function: Chemotaxis; bactericidal effect
3. Basophils
a. Minimum quantity
b. Function: allergic reaction
4. Eosinophils
a. Morphology: The nucleus is divided into two lobes.
b. Inhibit allergic reactions and bactericidal effect
5. Lymphocytes
a. The highest content
b. LM: The nucleus is round or oval, with a shallow concave on one side, the nucleus is large and basophilic.
c. Function: Main immune cell, involved in immune response
d. Classification: B, T, NK (natural killer cells)
6. Monocytes
a. LM: The largest volume, horseshoe- or kidney-shaped nucleus, basophilic cytoplasm, composed of azurophilic granules
b. Function: Single core-phagocytic system
c. Pass through blood vessels and enter tissues to transform into macrophages (histiocytes)
7. Platelets
a. Source: megakaryocyte fragments
b. LM: Biconvex disc shape, no nucleus, complete organelles and cell membrane
c. Function: Participate in hemostasis and coagulation
