18 of 44
White Pulp of spleen tissue
Lymphatic tissue, lymphocytes, macrophages contained
19 of 44

22 of 44
Liver of foetus and red bone marrow in adult
Where are blood cells manufactured (2 places)
23 of 44
red blood cells
Have active life of about 4 months before they are phagocytosed and replaced
24 of 44
platelets
Cells that plug the gaps in damanged blood vessels
25 of 44
Granular leucocytes and agranular leucocytes are red or white blood cells
white
26 of 44
Granular leucoytes
eosinphils, basophils, and neutrophils
27 of 44
Eosophils
These granular leucoytes release histamine and phagocytise antigen/antibody complexes and destroys parasitic worms and large particles
28 of 44
Basophils
This granular leucocyte develop into Mast Cells
29 of 44
Mast Cells
Large cells filled with histamin that attract antibody IgE to their surface and when activated they release histamine
30 of 44
Neutrophils
These granular leucoytes kills and ingests bacteria and disposes of dead material
31 of 44
These 3 cells make up the lymphocytes
B, T and NKC
32 of 44
T & B Cells
These 2 lymphocyte cells are involved in production of antibodies
33 of 44
T Cells
This lymphocyte cell destroys bacteria, viruses, fungi and cancer cells
34 of 44
Natural Killer Cells
These lymphoyte cells move freely in the body and destroy bacteria and tumour cells
35 of 44
Monocytes
Carried by the blood into tissue then enlarge into macrophages
36 of 44
Compliment
When this antimicrobial protien is activated it forms a cascade of chemical reactions that enhance phagocytes
37 of 44
Transferrin
this antimicrobial protien inhibits the growth of some bacteria
38 of 44
Interferons
This antimicrobial protien interferes with the ability of viruses to multiply
39 of 44
