what do RBC do?
|
transports oxygen and carbon dioxide
|
|
|
Another name for RBC
|

|
|
|
present at the juction between the erythrocytes and the plasma
|
buffy coat
|
|
|
what does the buffy coat contain

|
The hematocrit (Ht or HCT) is?
|
the % of blood volume that consists of ery/rbc.amount of red cells compared to other cells
|
|
|
The packed cell volume (PCV) can be determined by
|
centrifuging blood in a capillary tube (also known as a microhematocrit tube) at 10,000 RPM for five minutes.[2] This separates the blood into layers. The volume of packed red blood cells, divided by the total volume of the blood sample gives the PCV. Because a tube is used this can be calculated by measuring the lengths of the layers.
|

Each hemoglobin molecule consists of ? chains of amino acids(four polypeptides) each of which bears an iron atom that is the binding site for oxygen molecules.
|
Four chains
|
|

|
Anemia
|
|
|
Pernicious Anemia? many in elderly people.
|
Your body is not absorbing Vit B12 properly. Not that you don't get enough in your body. Your intrinsic factor is not working properly.
|
|
|

what is the difference between Hemoglobin and Hematocrit?
|
Hemoglobin (Hgb) is the iron-containing protein that bonds with oxygen, allowing the red blood cells to transport oxygen throughout the body. Hematocrit measures the portion of blood volume made up by red blood cells.
