Leukocytes

Question 6

What are erythrocytes?

Answer 6

Red Blood Cells

Question 7

What are thrombrocytes?

Answer 7

Platelets

Question 8

What are leukocytes?

Answer 8

White Blood Cells

Question 9

What do RBC’s do?

Answer 9

RBC’s (erythrocytes) make up about 40-45% of the blood volume. They carry oxygen to your body and bring CO2 back to your lungs.

Question 10

What doe Plt’s do?

Answer 10

made in bone marrow, platelets form clots and stop the bleeding. (Blood stuf comes from stem cells in our bone marrow)

Question 11

What do WBC’s do?

Answer 11

defense system, they attack foreign objects

Question 12

What percent of your blood is plasma?

Answer 12

about 55% - More than half the blood is made of plasma.

Question 13

What percent of your blood is RBC?

Answer 13

about 45%- RBC makes up just under half of the blood.

Question 14

About what percent of your blood is Plt or WBC?

Answer 14

Plt and WBC combined make up less than 1% of your blood, and platelets outnumber wbc by about 30 to 1

Question 15

What is there more of: RBC, Plt or WBC?

Answer 15

The ratio of RBC to Plt to WBC is about 600:30:1. For every 1 WBC, there are 30 Plt and 600 RBC

Question 16

What is RBC? What does it measure?

Answer 16

The number of red blood cells in a microliter of blood (usually about 5,000,000)

Question 17

What are PLt? What does it measure?

Answer 17

The number of platelet cells in a microliter of blood (usually about 250,000)

Question 18

What is WBC? What does it measure?

Answer 18

The number of White blood cells in a microliter of blood (about 8,000)

Question 19

How do RBC, PLt and WBC compare to eachother in the blood?

Answer 19

It’s about 600:30:1 ratio.

Question 20

How can you use the 600:30:1 ratio to help you find a normal count?

Answer 20

MULTIPLY BY 8k. 600:30:1 x 8k= 4800k : 240k : 8k. Or 4.8milliion : 240k : 8,000

Question 21

How big is a mcL? A microliter?

Answer 21

Well, a cc, cubic centimeter (1cmx1cmx1cm), is a ml (about the size of a sugar cube). If you break that cube into 1000 little sugar crumbs, that is a mcL

Question 22

Give an example of someone with “normal” RBC, PLT and WBC counts:

Answer 22

in each mcL, you would expect about 4,800,000 RBC and 240,000 Plt and 8,000 WBC in mcg (one tiny little spec of sugar).

Question 23

What is the normal range for RBC?

Answer 23

4-6 million cells/mcL

Question 24

What is the normal range for Plt?

Answer 24

150k to 450 cells/mcL

Question 25

Wht is the normal range for WBC?

Answer 25

5k to 10k cells/mcL

Question 26

is the % of blood the same as g/dL

Answer 26

About. A dL of blood weighs about 100g. So each g/dl is about 1%

Question 27

Wht is hemoglobin? Where is it? What does it do?

Answer 27

Hemoglobin is the protein in the RBC that carries 02 and C02.

Question 28

How much of the red blood cell is made of hemoglobin?

Answer 28

About 1/3 of the RBC is Hgb.

Question 29

What percent of the blood is hemoglobin?

Answer 29

Since RBC is about 45% and Hgb 1/3 or that, about 15% of the blood is Hgb.

Question 30

What is Hct? What does it measure?

Answer 30

Hct is Hematocrit. It measures the PERCENT (not g/dL)of your blood that is composed of RBC. Which should be about 45%

Question 31

What should we expect for ah Hct measure?

Answer 31

Since RBC is about 45% of your blood you expect 45%. Remember that hemoglobin is about a third of that (or 15%)

Question 32

What is Hgb? What does it measure?

Answer 32

Hemoglobin count.It measure the the amount of hemoglobin in the blood in g/dL (close to percent)

Question 33

What is Hgb measured in?

Answer 33

It is measured in g/dL (but that is pretty much percent)

Question 34

What should we expect for an Hgb measurement.

Answer 34

15 g/dL. Since RBC is about 45% (or 45 g/dL) of blood and Hgb is a third of that, you expect about 15% of blood to be hemoglobin (OR 15 g/dL)

Question 35

What is the normal range for Hgb

Answer 35

(avg is 15) range is 12-18 g/dL (remember hgb is about a third of hct)

Question 36

What is HCT measured in?

Answer 36

Hematocrit is measured in percent.

Question 37

How are Hbg and HCT measured differently?

Answer 37

HematocriT is measured in percenT (they both have a t). Hemoglobin is measured in g/dL (no t’s)
