Natural Antibodies
Definition
anti-A and anti-B antibodies, because they naturally occur without exposure to the correspondig antigens

Definition
when they react with incompatible serum antibodies, agglutination, or clumping and sticking together of RBCs occurs
Term
Antigen
Definition
  • Marker molecules which identify cell types
  • form the basis of the immune response protection against viruses and bacteria
  • produce protein antibodies that are specific for that particular type of non-self antigen - which will hopefully neutralize the invading microbes

 

Term
Cardiac Output
Definition
  • a measure of blood flow - volume of blood pumped by the heart each minute

 

CO = HR x SV

 

Cardiac output = mL of blood/minute

Term
Flow
Definition

The movement of blood through the circulatory system.

Directly proportional to pressure and inversely proportional to resistance

Term
Rh Factor
Definition
  • Presence or absence of the Rh, or D, antigen
  • RBCs with the D-antigen are Rh+
  • RBCs lacking the D-antigen are Rh-
  • not natural antibodies

The anti-Rh antibodies only appear in the blood of Rh- individual after exposure to Rh+ RBCs
