Term
What is centrifuging?
Definition
spinning
Term
What is an example of a heterogeneous mixture?
Definition
suspension
Term
What form a very thin buffy coat above a thick RBC layer of centrifuged blood?
Definition
WBC and platlets
Term
Since hemocrit is mainly RBC, it is often called what?
Definition
packed cell volume (PCV)
Term
What are RBC's structure?
Definition
biconcave discs with a thin center and a thick outer margin wit a large surface area that allows for quick oxygen exchange
Term
What do RBC not have?
Definition
nucleus or ribosomes
Term
How long do RBC live after traveling about 700 miles?
Definition
about 120 days
Term
What do the alpha and beta chains bind to forming caraminohemoglobin?
Definition
carbon dioxide
Term
oxygen carrying capacity of blood is reduced cut outlaw hematocrit or low blood hemoglobin concentrations causing oxygen starvation, weakness, lethargy, confusion, etc;
Definition
anemia
Term
Macrophages form where monitor the condition of circulating RBCs and engulfs them before they homeless or rupture?
Definition
liver, spleen, and bone marrow
Term
presence of intact RBC in urine (occurs after kidney damage or damage to vessels along urinary tract)
Definition
hematuria
Term
After each heme is stripped of its iron, what is it converted into?
Definition
biliverdin?
Term
What is biliverdin?
Definition
organic compound with a greenish color (bad bruises develop a greenish color due to biliverdin formation in blood filled tissues)
Term
What is biliverdin converted to?
Definition
bilirubin
Term
What is bilirubin?
Definition
an orange-yellow pigment and released to bloodstream
Term
because a lot of free iron is toxic to cells, what does a iron bind to so that new hemoglobin is made?
Definition
trasferrin (a plasma protein)
Term
the only site of RBC production in adults as well as the primary site of WBC production
Definition
red bone marrow
Term
What is the production of RBCs termed?
Definition
erythropoiesis
Term
What produce myeloid stem cells which develop to RBC and lymphoid stem cells which develop into lymphocytes?
Definition
hemocytoblasts in bone marrow
Term
What requires adequate supplies of amino acids iron, and vitamins B12, B6, and folic acid?
Definition
normal erythropoiesis
Term
Where can you get vitamin B12 from?
Definition
dairy products and meat
Term
What does the absorption of vitamin B12 require the presence of?
Definition
intrinsic factor produced in the stomach
Term
Without B12 and intrinsic factor, what results?
Definition
pernicious anemia
Term
state of low tissue oxygen levels
Definition
hypoxia
Term
athletes attempt to elevate their hemacrits by rein fusing packed RBCs that were removed and stored at an earlier date
Definition
blood doping
Term
What is the goal of blood doping?
Definition
to improve oxygen delivery to muscles which enhances performance but elevated blood viscosity increases the workload on the heart
Term
What are substances that can trigger a protective defense mechanism called an immune response?
Definition
antigens
Term
What are the surface antigens your blood has to determine blood type?
Definition
A, B, and Rh (or D)
Term

Definition
Rh+
Term
If there is no Rh antigen present on is what?
Definition
Rh-
Term
What is the universal blood donor?
Definition
O-
Term
What is the universal blood recipient?
Definition
AB+
Term
What ignores the surface antigens called agglutinogens on your RBC?
Definition
immune system
Term
What contains antibodies called agglutinins that will attack antigens on foreign RBCs causing agglutination or clumping?
Definition
plasma
