Intro to Hematology

Cells that are in the blood

Erythrocytes
Leukocytes
Platelets

PPE when working with blood

Gloves

PPE when working with stains

gloves and goggles

Erythrocyte (RBC=Red blood cell)

The msot abudndant blood cell, contain hemoglobin

Transport O2 throughout the body

Thrombocyte (platelets)

Function- Hemostasis (clotting) stop bleeding by sticking to damaged vessels and clumping together, release proteins that help form a clot.

Leokocytes (WBC=White blood cell)

Colorless (white) cells capable of movement that provide body defense

Five Types -

Granulocytes-have granules in cytoplasm

1Neutrophil

2. basophil

3. Eosinophil

Agranulocytes -no granules in cytoplasm

1. Lymphocute

2. Monocyte

Neutrophil

Funnction- to stop or slow down forgein organisms

• They work by 🇦

-Phagocytes- to eat bacteria and dead cells

-Bacteriocidal- to kill bacteria

Basophil

Functions

-phagocytosis-

-act against allergic reactions

-produce heparin and histamine

Eosinphoil

Function

-moderate the inflammatory response

-phagocytosis

Lymphocute

plays a vital role in immunity

-T cells (memory cells); cells are sanitized to an antigen,remembers tht antigen and fight it off next time

B-Cell; divide to form many cells to fight an antigen

Monocyte

largest blood cell, irregular shaped nucleus

-function is phagocytosis
