Intro to Blood

What are antigens?

substance the body sees as foreign

What are antibodies?

“recognizers” present in plasma

what is agglutination?

the binding of antibodies that causes RBC’s to clump together

What group types is blood split into?

A, B and O

What are Blood Groups types based on?

the two antigens a person inherits

What are the two types of antigens a person can inherit

Type A and Type B?

Type O has the-

absence of A/B antigen

Type AB has the-

presence of both A/B antigens

Type A has the-

Only the A antigen

Type B has the-

Only the B antigen

A blood groups have-

A antigen on the surface of RBC and B antibodies in plasma

B Blood Groups have-

B antigen on surface of RBC and A antibodies in plasma

AB Blood groups have-

A&B antigens on surface of RBC and NO A or B antibodies in plasma

O Blood Groups have-

NO A or B antigens on surface of RBC and A&B antibodies in plasma

Is the ABO gene autosomal?

No,

is the ABO gene present on either sex chromosome?

No

Is O type recessive?

Yes

are type A and B dominant?

Yes

what is the Rh factor?

an inherited protein found on the the surface of the red blood cell

\+ type blood means

Rh protein is present

\- type blood means

Rh protein is not present

what is the primary function of the erythrocytes

to carry oxygen in blood to all cells of the body

Leukocytes are what type of cell?

White Blood Cell

True or False: White Blood Cells are the only complete cell in the body?

True

granulocytes are:

type of immune cell that has granules with enzymes

granulocytes include

neutrophils, eosinophils, basophils

what are the first cells to arrive when experiencing a bacterial infection?

Neutrophils

the presence of eosinophils in the body can indicate what?

parasitic infection, allergen, cancer or inflammation

what is the rarest type of White Blood Cell

Basophils

what is histamine

inflammatory chemical that makes blood vessels leaky and attracts other WBC to the inflammatory cite

what is the largest type of WBC

monocytes

what is the function of monocytes

to migrate into tissues and change into macrophages to help fight chronic infections.

What are the 3 phases of hemostasis

1. vascular spasms occur 2. Platelet plug forms 3. Coagulation events occur

What happens in the step of “Coagulation events occur”

thrombin clauses clotting and converts fibrinogens to fibrin and then fibrin forms mesh that straps RBC and platelets

what are damages or dead RBC recycled by?

Phagocytes

what is hematopoiesis

the production of blood cells and platelets
