erythroblastosis fetalis
Baby is Rh positive Mother is Rh negative
Sicled red blood cells have an abnormal shape and do not tend to form stacks of cells. What does this do to sedimentation rate?
Decreases.
How is ESR useful in female patient suffering from severe abdominal pains?
Elevated ESR could indicate PID.
Which hormone, secreted by the kidney, is responsible for increased production of RBC's
Erythropoetin
4 ways the body uses cholesterol
Forming cell membranes Making bile salts Making steroid hormones like estrogen and testosterone Making vitamin d
Connection between high blood cholesterold and atherosclerosis?
High cholesterol can idicate atherosclerosis.
Why do Hemoglobin values rise in COPD?
In COPD there is inadequate 02 in the blood. The kidneys respond to this condition of hypoxia by releasing a hormone called erythropoietin. Erythropoietin stims the production of red blood cells, which contain hemoglobin.
The blood of a cancer patient is given an ESR test. The results show a slower ESR from the previous month. What might this indicate?
Less inflammation = improvement in pt cancer
Atherosclerosis risk factors
Lipid deposits on the walls of large arteries
Most cholesterold is made by what organ?
Liver
Why are hematocrit values lower in women?
Meunstration, hematocrit is inversely proportional to bodyfat, androgens (in males) stimulate Rbc production.
If you have type O blood, which antigens are present on your red blood cells?
Neither a or b
Is the ESR test a specific test used to diagnose a disease?
No
Why does high altitude result in increased hematocrit?
There is less oxygen in the air at higher elevation. The kidneys respond to hypoxia by secreting the hormone erythropoetin, which stimulates RBC production.
Each heme group contains an atom of the element
iron
Most american are Rh
positive
Healthy female hemoglobin
14 g/100 ml blood
Healthy male hemoglobin
16 g/100 ml blood
High blood cholesterol
200 mg/100ml
Least common ABO blood type
AB
High density lipoproteins transport cholesterol from the ______ to the ______.
Peripheral tissues Liver
Hemoglobin values decrease in renal disease. Give a possible explanation for this
The kidneys respond to hypoxia by secreting the hormone erythropoietin, which stimulates red blood cell production. If the kidneys are damaged in renal disease, they may not be able to secrete sufficient erythropoitin.
What is the most common ABO blood type in the US
Type O
Anemia
a decrease in the oxygen-carrying ability of the blood
Pernicious anemia
lack of mature erythrocytes caused by inability to absorb vitamin B12 into the bloodstream
LDL's transport cholesterol
to the peripheral tissues of the body, maing it available for membrane or hormone synthesis.
Male with polycythemia
20 g g/100 ml blood In polycythemia, there are above-normal numbers of red blood cells. Hemoglobin molecules fill red blood cells. So, more red blood cells reults in more hemoglobin.
Each heme group can transport _________ molecules of 02?
4
How many polypeptide chains form the globin portion of the molecule?
4
What color is oxyhemoglobin?
4
how many heme groups are contained in one molecule of hemoglobin
4
the female with iron-deficiency anemia
8 g/100 ml blood In iron-deficiency anemia, there are not enough atoms of iron for the body to use in manufacturing hemoglobin.
If your blood agglutinates with both anit-a and anti-B sera, your blood type is
AB
High/fast ESR
Active inflammation in the body
Gene allele
dictates trait
Agglutinins
Antibody to agglutinogens, found pre-formed in the blood plasma.
What causes low density lipoproteins
Cigarettes Stress Coffee
Long term athletic training will cause a person's hematocrit to
Increase
How does deficiency of intrinsic factor lead to pernicious anemia?
Intrinsic factor, made in the stomach, is necessary for the absorption of vitamin B12 from the diet.
Why would a diet deficient in iron lead to anemia?
Iron is an important element in hemoglobin. Without adequate iron, the body cannot manufacture enough hemoglobin to fill RBC's.
What increases levels of high density lipoproteins?
Regular aerobic exercise.
Lipoproteins
clusters of lipids associated with proteins that serve as transport vehicles for lipids in the lymph and blood
Anemia causes hematocrit to
decrease
Blood type O is the universal donor. However, if transfused into blood type B, what is important to remember?
You must separate the blood into packed cells and remove the plasma. The type b person will attack the 0 type plasma.
Agglutinogens
antigens on the surface of the RBC that is the basis for blood typing
Which antibodies are present in your blood if you are a type 0
both anit-A and anti-B
