Blood Types

Question 1

Rh Factor

Answer 1

• second protein marker (antigen) that affects identification of blood
• inherited from parents
• Rh+ = people with Rh proteins in blood
• Rh- = people w/o Rh proteins in blood (may have anti-Rh antibodies)

Question 2

Rh Factor: Anti Rh Antibodies

Answer 2

• anti-Rh antibodies are not always present
• anti Rh antibodies are only present after first exposure to Rh+ blood
• Rh- recipient can recieve Rh+ once
- but this will stimulate production of anti-Rh antibodies
• 2nd transfusion of Rh+ will cause agglutination in Rh- patient (can cause death)

Question 3

Blood Type Compatibility

Answer 3

• blood transfusion: receiving blood into one’s body
• identifying blood type is crucial for blood transfusions
• mismatched blood types cause agglutination (clumping of blood)
• agglutination leads to clogged blood vessels, blocked circulation, damage to body, and possibly death
