Chapter 19 - Blood Flashcards
Liquid connective tissue that consists of cells surrounded by a liquid extra cellular matrix
Blood plasma
This suspends various cells and cell fragments
Blood plasma
3 general functions of blood
Transportation, regulation, protection
Foreign substances like bacteria and viruses that stimulate the production of antibodies
Antigens
This is determined by the type of chemical substances (antigens) found in the plasma membranes of an individual’s red blood cells
Human blood types
This blood type is determined by the type of sugars attached to the membrane
ABO blood types
This blood type is determined by the type of proteins in the membrane
Rh blood types
4 blood types
A, B, AB, O
Blood type contains A antigens
A
Blood type that contains B antigens
B
Blood type containing both type A and type B antigens
AB
Blood type lacking both A and B antigens
O
Inheritance of ABO blood types is based upon?
Multiple alleles
Instead of just 2 types of alleles for a trait, there are how many? They are?
3 A, B, O
Both A and B alleles are dominant to?
O
Are A and B alleles dominate to each other?
No
There are 6 genotypes possible for inheritance. They are?
AO (type A), AA (A), BO (B), BB (B), AB (AB), OO (O)
Rh positive individuals contain the Rh factor where? Do Rh negative individuals contain the trait there?
In their RBC’s, No
This individual may contain 2 Rh positive genes (++) or 1 Rh positive gene and 1 Rh negative gene (+-).
Rh positive
Which gene is dominant to Rh negative?
Rh positive
This type of individual may contain 2 Rh negative genes (–)
Rh negative
During medical emergencies involving blood loss, this may be given to an individual
Blood transfusions
What happens if an individual is given blood containing antigens he/she does not normally have?
The immune system is stimulated to attack the transfused cells
Rh negative individuals can receive only what kind of blood?
Negative
