What are leukocytes?
White blood cells.
What are the functions of leukocytes?
Defend against pathogens and remove toxins, wastes, & damaged cells.
Do leukocytes function in the circulatory system?
WHY WOULD THEY KIDDO?
Where do leukocytes move from and to?
From blood vessels into tissues.
What is diapedesis?
Squeeing out of the BV's and going to different tissues.
What are the 2 classifications of leukocytes?
Granulocytes and agranulocytes.
Characteristics of granulocytes?
Granular inclusions in cytoplasm.
Characteristics of agranulocytes?
No visible granules.
What are the types of granulocytes?
Neutrophils, eosinophils, and basophils.
What percent of WBCs are neutrophils?
Characteristics of neutrophils?
Lobed nucleus and very mobile.
Functions of neutrophils?
1st defense against microorganisms, phagocytic, and attract more neutrophils.
What percent of WBCs are eosinophils?
Characteristics of eosinophils?
Bi-lobed nucleus and red granules.
Functions of eosinophils?
Attracted to injuries, phagocytize compounds bonded with antibodies, and increase during allergic reactions.
What percent of WBCs are basophils?
Characteristics of basophils?
S-shaped nucleus and blue granules.
Functions of basophils?
Release anticoagulants and release histamine (causes inflammatory response and attracts other WBCs).
What are the types of agranulocytes?
Monocytes and lymphocytes.
What percent of WBCs are monocytes?
Characteristics of monocytes?
Largest cells in blood.
Functions of monocytes?
Recruit mre monocytes, attarct fibroblasts, and pahgocytize foreign material (fuse to form osteoclasts and form free and fixed macrophages).
What percent of WBCs are lymphocytes?
Characteristics of lymphocytes?
Mature in lymph organs, smallest, and non-phagocytic.
Functions of lymphocytes?
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 do T-cells do?
Attack foreign cells directly.
What do B-cells do?
Differentiate into plasmocytes that produce antibodies.
What do NK cells do?
Immune surveillance and destruction of abnormal cells such as cancer cells.
What are thrombocytes?
What are platelets made of?
Smalle, anucleate cell fragments.
Where do platelets come from?
What do platelets do?
Produce proteins for blood clotting.
How long do platelets last?
About 10-12 days.
What is blood clotting called?

Transport of important clotting agents, formations of a temporary patch and clot contraction.
What is hemopoiesis?
All blood cells are derived from a pluripotent stem cell.
What cells are not derived from the resulting myeloid tissue?
Where are all new blood cells produced in adults?
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.

How is blood type determined?
What determine your blod type?
A,B, and Rh.
What antigens can people have?
A, B, AB, or none.

What is the Rh group named after?
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?
