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
