3. Circulatory System Functions
Respiratory – O2 and CO2 exchange
Excretory – removes waste from body cells
Protection – clotting, transports white blood cells to infections
Nutrition – carries energy and food throughout the body
Regulatory – helps to maintain pH and temperature
Hormonal – transfers hormones to organs

Structure of Blood
Blood is composed of :
40% cells and %60 plasma
The cells that in the blood are:
Erythrocytes (red blood cells)
Leukocytes (white blood cells)
Platelets
Laboratory Techniques TM

8. Erythrocyte (red blood cell)
The most abundant blood cell
Function – transport O2 throughout the body
Mammals – no cell nucleus
Birds & Reptiles –cell nucleus

9. Laboratory Techniques TM
Neutrophil
Function- to stop or slow down foreign organisms
They work by:
Phagocytosis – to eat bacteria and dead cells
Bacteriocidal – to kill bacteria
Laboratory Techniques TM

10. Laboratory Techniques TM
Basophil
Functions –
Phagocytosis
Mediate allergic reactions
Produce heparin and histamine
Laboratory Techniques TM

11. Laboratory Techniques TM
Eosinophil
Functions –
Moderate the inflammatory response
phagocytosis
Laboratory Techniques TM

12. Laboratory Techniques TM
Lymphocyte & Monocyte
Lymphocyte – plays a vital role in immunity
T-cells (memory cells) – cells are sensitized to an antigen, remember that antigen and fight it off next time
B-cells – divide to form many cells to fight an antigen
Monocyte – largest blood cell
Function is phagocytosis
Laboratory Techniques TM

13. Laboratory Techniques TM
Thrombocyte
Function –
Hemostasis (clotting) – stop bleeding by adhering to damaged vessels and clumping together, release proteins that help form a clot
