Presentation Transcript

  1. Blood lab

  2. Blood composition • Plasma – fluid, gives volume contains antibodies • Platelets – helps in clotting of blood • White blood cells – used in defense against foreign invaders • Red blood cells – carry oxygen Blood after it has been centrifuged

  3. Blood Genetics • In blood type genetics*, there are: ____________ genes OR alleles that Produce ____________ blood proteins that Result in ____________ blood types that Establish ____________ genotypes THREE TWO FOUR SIX *See wkst #4

  4. TERMS TO KNOW • Protein- antigen (ag) or agglutinogens • Antibodies- agglutinin- fight against foreign particles • Coagulation: Blood clotting • Agglutination: Blood clumping • RBC = Red blood Cell

  5. RBC Has Antigens

  6. Blood Groups Are Based On RBC Antigens (Ag) ‘A’ Ag Rh+ Antigen

  7. Blood Groups: B+ and B- ‘B’ Ag Rh+ Antigen

  8. Blood Groups: AB+ and AB- ‘A’ Ag ‘B’ Ag Rh+ Antigen

  9. Blood Groups: O+ and O- Rh+ Antigen

  10. Plasma Has Antibodies http://www.lrc.arizona.edu/courses/mmiweb/lake/immunology_modules/hemagglutination/hema2.html

  11. Remember RBC Has Antigens

  12. Antibodies Can Bind To Antigens

  13. Clumping of Blood

  14. YES NO NO NO YES YES NO

  15. RECIPIENT DONOR + - - + - + + - - + + + - - - -

  16. Rh Factor RR, Rr rr yes no anti Rh no Moms that have Rh negative blood will have antibodies/ fight against a baby with the Rh protein (positive).

  17. 1st Baby Is Rh + ; Mom is Rh - Baby’s blood enters mom’s blood, transferring Rh+ Antigens to mom

  18. 1st Baby Is Rh +; Mom Is Rh - Mom Makes Antibodies against Rh+ Antigens In Her Blood

  19. 2nd Baby Is Also Rh + Mom’s Antibodies Attack The RBC’s In The 2nd Baby

  20. Erythroblastosis Fetalis

  21. Anti Rh + Antibodies (Rhogam)

  22. Rhogam Destroys Rh + Antibodies In Mom

  23. 1st Baby Is Rh + Rhogam prevents Mom From Making Antibodies against Rh+ Antigens

  24. 2nd Baby Is Also Rh + With Rhogam, Mom’s Blood Does Not Attack The RBC’s In The 2nd Baby

  25. Jaundice in Infants • Complications Due to ABO Incompatibility Are Rare!

  26. RXN NORXN TYPE O TYPE A TYPE B TYPE AB http://waynesword.palomar.edu/aniblood.htm
