What is the causes of Anemia?
- Iron-deficiency (secondary to hemorrhage; inadequate
intake; impaired absorption) - Deficiency of vitamin B12 (inadequate intake; impaired
absorption) - Premature RBC destruction (genetic; autoimmune)
- Defective erythropoesis (leukemia and other
myeloproliferative disorders)

- Vascular spasms – immediate vasoconstriction in
response to injury - Platelet plug formation
- Coagulation (blood clotting)

AB
Which blood group can only receive blood from one bloodtype?
O
What antibody contains the blood group B of?
B
What is the main function of the Lymph system? (3st)
- Provide drainage of interstitial fluid
- Transport lipids from the gastro-intestinal canal
- Immune response
What is the organs in the lymphsystem? (5st)
Thymus, Spleen, Tonsils, Peyer’s patches, Appendix
What does the Spleen?
It is the ‘‘blood filter’’
- Removes old red blood cells
- Storage of plates
- Production of blood cells during fetal life
What is the function of Peyer’s patches?
The function of Peyer’s patches is to analyze and respond to pathogenic microbes in the ileum
