11.

Thrombocytes

Fluid portion of blood

White blood cells, fight infection

Another name for platelets that help form clots around wounds

An iron-containing protein in red blood cells that reversibly binds oxygen.

Question 12

12.

Blood Type

Type AB

Determined by the type of antigen present on the surface of red blood cells; inherited from parents

Type OB

Type A

Question 13

13.

Agglutinogens

Fluid portion of blood

Determined by the type of antigen present on the surface of red blood cells; inherited from parents

An iron-containing protein in red blood cells that reversibly binds oxygen.

Antigens on the surface of the red blood cells that is the basis for human blood typing

Question 14

14.

Blood Type A

Type AB antigens

Blood with A antigens and anti-B antibodies; genotype = AA or AO

Type OB antigens

Another name for platelets that help form clots around wounds

Question 15

15.

Blood Type B

Blood with B antigens and anti-A antibodies; genotype = BB or BO

Another name for platelets that help form clots around wounds

An iron-containing protein in red blood cells that reversibly binds oxygen.

Type OB antigens

Question 16

16.

Blood Type AB

Blood type with A antigens and anti-B antibodies; genotype = AA or AO

Blood type with B antigens and anti-A antibodies; genotype = BB or BO

Blood type with OB antigens

Blood with both A and B antigens, no antibodies; genotype = AB

Question 17

17.

Blood Type O

Blood type with both A and B antigens, no antibodies; genotype = AB

Blood with no antigens, A and B antibodies' genotype = OO

Blood type with OB antigens

Blood type with B antigens and anti-A antibodies; genotype = BB or BO

Question 18

18.

Universal Donor

A person with type B antigens and anti-A antibodies; genotype = BB or BO

A person with both type A and B antigens, no antibodies; genotype = AB

A person with no antigens, A and B antibodies' genotype = OO

A person with type O blood; type O blood has no antigens that can be attacked by the host's blood, so it can be donated to anyone

Question 19

19.

Universal Recipient

A person with type O blood; type O blood has no antigens that can be attacked by the host's blood, so it can be donated to anyone

A person with type AB blood; type AB blood has neither A nor B antibodies, so a universal recipient can safely receive a transfusion of any blood type

A person with no antigens, A and B antibodies' genotype = OO

A person with type B antigens and anti-A antibodies; genotype = BB or BO

Question 20

20.

Rh Factor

Refers to the presence or absence of the Rhesus antigen on red blood cells.

Low count of red blood cells in the body

Low count of white blood cells in the body

A person with no antigens, A and B antibodies' genotype = OO

Question 21

21.

Transfusion

The transfer of white blood cells

The transfer of red blood cells

The transfer of blood or a blood component from donor to recipient

The transfer of blood with OB antigens

Question 22

22.

Abbreviation that refers to the analysis of bloodstain patterns

Abbreviation that refers to the analysis of blood spatter

Abbreviation that refers to the analysis of blood droplets

Abbreviation that refers to the analysis of dried blood

Question 23
