factor/protein/antigen in blood named for the Rhesus monkey
What does Anti-B serum contain?
What blood type is indicated if agglutination occurs in Anti-B serum?
Blood type B or AB
clotting cascade results in fibrous network trapping blood cells
platelets become "sticky," cling to fibers, attract more platlets
platelets release serotonin; blood vessels narrow
What is Hemostasis?
the stopping of the flow of blood
The 3 Phases of Hemostasis (in order)
1) Platelet plug formation
2) vascular spasms -> narrowed blood vessels
3) blood coagulation
What blood type has A agglutinogens (antigens)?
Blood type B has what kind of antigens (agglutinogens)?
If you have a type A blood, what agglutinins (antibodies) do you have?
What blood type has A antibodies (agglutinins)?
True or False?
Blood type AB has AB agglutinogens and O antibodies
False; Type AB has AB agglutinogens and no antibodies
True or False?
Blood type O has O antigens and AB antibodies
False; Type O has no antigens and AB antibodies
Blood type A can only GIVE blood to groups...
A or AB
Which blood type can RECEIVE blood from AB, A, B and O?
Blood type AB
Blood type O can receive blood from groups...
This blood type can GIVE to groups B and AB, and RECEIVE from groups O and B
Blood type B
What blood groups can type O GIVE?
Types A, B, AB and O
How many types of antigen surface markers exist that identify the Rh blood type group?
One; the D- antigen
True or False?
There are 3 types of antigen surface markers that exist to identify the ABO blood type groups
False; There are two
What determines if your blood type is positive or negative?
If the Rh factor ( D-antigen) is present, then your blood type is positive. If it's not present, then you're negative.
What antibodies are present in your blood plasma if you have Type O blood?
What antibodies are present in your blood plasma if you have Type A blood?
What antibodies are present in your blood plasma if you have Type B blood?
What antibodies are present in your blood plasma if you have Type AB blood?
What is the Y shaped structure called?
If the antibody and the antigen are matching (same letter), would agglutination occur?
No, only if it's not matching. Ex: B antigen and A antibody would clump.
If a recipient has type B+ blood and the donor has O+ blood, would they clump?
No, because the recipient has A antibodies and the donor doesn't have any antigens for it to match up with to cause agglutination.
If a recipient has type AB- blood and the donor has type B+ blood, would they clump?
Yes, because recipient is AB- he/she will have an Rh antibody since it's not present in the antigen. And since the donor is B+, he/she has a Rh antigen for the recipient's Rh antibody to match up with to cause agglutination.
abnormal widening or ballooning of weak area in artery wall
blood clot breaks away from origin; travels in bloodstream; eventually clogs vessels
blood disease cause by Plasmodium parasite; infects/destroys RBC
bone marrow cancer, increased number of WBC
clot in unbroken blood vessel; can be deadly in heart or brain
decrease in O2 carry capacity; lower than normal RBC; deficient hemoglobin
hereditary; normal clotting factors missing; takes long time for blood to clot
inherited; abnormal hemoglobin; RBCs become sickle shaped (misshapen)
sickle cell anemia
living cells portion of blood
liquid matrix of blood; carries dissolved substances
What is another name for RBCs?
What is another name for WBCs and what does it function in?
Leukocyte; function in defense
What particle is needed for blood clotting?
What is the common blood stem cells?
What is the blood stem cells that become B-cells and T-cells?
What is the blood stem cell that become most of formed elements?
What aids in the process of hemostasis?
What is the primary function of blood?
Transport nutrients, heat, waste, gases
What role does blood play in cooling the body?
vasodilation; blood cooled near skin
What is vasoconstriction?
It's how blood heats the body, by pooling blood towards torso
clotting of blood, defense (antibodies), lipid transport
The less dense liquid that's about 55% of the blood volume
Blood is scarlet red in color when loaded with what?
These fragments are to form platelets
The least numerous leukocyte is the?
The most numerous leukocyte is the?
Where does hematopoiesis take place?
Red Bone Marrow

What is the primary multipotent stem cell in hematopoiesis?
What is hemoglobin?
iron containing protein that binds to oxygen
What is the leukocytes blood levels?
normal is 4,000-11,000 cells/mL
What is it called if you have over 11,000 leukocytes?
What is it called if you have under 4,000 WBCs?
What is granulocyte?
(stained) granules in cytoplasma
What are the 3 different granulocytes and their function?
1) Neutrophils - multilobed nucleus; phagocytes at site of infection
2) Eosinphils - large red granules; allergies & parasite worms

What is an agranulocyte?
It has no visible cytoplasmic granules
What are the 2 types of agranulocytes?
