Blood (hematopoietic system)

RBC

AKA: Erythrocytes, they are differentiated cells that derive from
hemocytoblast stem-cells located in the red bone marrow.

WBC

AKA: Leukocytes, combat invading microbes and other foreign materials, including dead cells breakdown products

BASOPHIL : secrete histamine (inflammation) and heparin (clotting)

EOSINOPHIL: two-lobbed nucleus; occur in allergic reactions to modulate inflammation (i.e., histamine destruction

NEUTROPHIL: a multi lobbed nucleus; phagocytize bacteria, Non-granulocytes

MONOCYTE: largest WBC; form macrophages to remove bacteria and debris

LYMPHOCYTE: smallest WBC; migrate to lymphatic tissues

HEME —→ HEMOGLOBIN

PLATELETS:

-small cell fragments that are formed from disk-shaped
plasma membrane and a small amount of cytoplasm

-They are formed in the blood plasma from megakaryocytes in the red bone marrow, with specific glycoproteins that allow attachment to collagen and connective tissue; they are primarily used for..

-Agglutination – binding to tissues to form a clot

-Adhesion - ‘stickiness’ factors that allow platelets to bind together in a net

-Aggregation – accumulation of platelets into a mass

Megakaryocyte

Hemocytoblast aka hematopoetic

Hematopoetic stem cell aka hemocytoblast

myeloid stem cell

sickle cell
