1st defense against microorganisms, phagocytic, and attract more neutrophils.
What percent of WBCs are eosinophils?
2-4%.
Characteristics of eosinophils?
Bi-lobed nucleus and red granules.
Functions of eosinophils?

1%.
Characteristics of basophils?
S-shaped nucleus and blue granules.
Functions of basophils?

20-30%.
Characteristics of lymphocytes?
Mature in lymph organs, smallest, and non-phagocytic.

Specific immunity: focuse on a single pathogen, produce antibodies, and destroy abnormal tissue.
What are the types of lymphocytes?
T-cells, B-cells, and NK cells.

What is blood?
Hi beautiful you probably did not get this answer exactly right but that is ok. I just wanted to leave a little surprise for you to see at some point. You have absolutely how much I LOVE YOU!!! you mean the world to me and when I am with you nothing else matters to me!!!! I am pretty sure time stops when I am holding you in my arms and I love it!! Until my next surprise bebe I love you mwahhhh mwahhhh!! Now quit procrastinating and continue to study.

The formation of WBCs.
Where do granulocytes complete their development?
Red marrow.
How long do neutrophils last?

When do monocytes complete development?
When they exit the circulatory system.
Where do immature lymphocytes go?
Bone marrow and thymus.
Where do lymphocytes mature?
Spleen, tonsils, or lymph nodes.
How long can lymphocytes last?
For several years.
RBC plasmalemma has what?
Surface antigens.
What are antigens?
Usually glycoproteins or glycolipids.
How is blood type determined?
By genetics.
What determine your blod type?
A,B, and Rh.
What antigens can people have?
A, B, AB, or none.
What do you produce antibodies for?
All antigens you do not have.
What happens when foreign antigens are introduced into your bloodstream?
You produce antibodies to destroy them.
What type of blood can AB patients receive?
Any blood
What type of blood can A patients receive?
A or O, and produces B antibodies.
What type of blood can B patients receive?
B or O, and produce A antibodies.
What type of blood can O patients receive?
Only O, produce both A and B antibodies.
What is the Rh group named after?
Rhesus macaque.
Reasons why you love KT???
There are way too many reasons to put on this flashcard silly! You just do, so accept it and give her a kiss
If you have Rh antigen you are?
Rh+.
If you have no antigen you are?
Rh-.
What is the Rh antigen somtimes referred as?
The D antigen.
When do Rh- people produce antibodies?
Only when exposed to the Rh antigen.
When does this usually occur?
When someone receives and Rh+ transfusion or pregnant with Rh+ baby.
What happens when an Rh- mother is pregnant with a second Rh+ baby?
The Rh- mother may reject the Rh+ baby.
Hi Katie!!!!!
I love you!!!!
