Cards

Term
What does blood transport?
Definition
Nutrients, oxygen to cells, carbon dioxide away to lungs, hormones to their targets.
Term
How does blood transport CO2 to the lungs?
Definition
Bicarbonate Ion
Term
What is the Temp of Blood?
Definition
38 Celcius
Term
What is the PH of blood
Definition
7.35-7.45
Term
Does blood help with passing fluids, outside of the body?
Definition
No, blood only helps with immunity and clotting. (Prevent loss)
Term
Does clot formation cause blood pressure to rise?
Definition
No, causes it to drop.
Term
What are the three elements of blood?
Definition
Red blood cells, white blood cells, and platelets.
Term
What are the three elements in blood suspended in?
Definition
Yellow-plasma
Term
How much blood is in the average male? (Hint you want to know this number exact).
Definition

5.2 quarts.

So know also 4.6-6.2 million rbcs in male. And 4.2-5.4 in females.

Term
What is the percentage of plasma in a normal human?
Definition
55%
Term
What is the percent of redblood cells in a nomal human? Leukocytes?
Definition
45%, and 1%( your bodies immune system is only 1%!!)
Term
What do we call our erythrocyte level?
Definition
Hematocrit. Hint- Think Ery(means red) cyte(means cell)
Term
Will the formed elements fall below the plasma in a test tube?
Definition
Yes. Plasma is 55% and Formed elements is 45%.
Term
Is a erythrocyte value of 49% normal?
Definition
No 43%-45%.
Term
If your erythrocyte level is 50%, is your blood thicker(viscosity) or thinner?
Definition
Thicker, this will raise blood pressure, slowing rate of flow.
Term
Describe a red blood cells characteristics.
Definition
Binocave, flexible, no nucleus, no mitochondria.
Term
A red blood cell, can reproduce?
Definition
No
Term
A red blood cell consume oxygen?
Definition
No, only carries 4 oxygen.
Term
Red blood cells are made of which protein?
Definition
Hemoglobin, giving it four chains, 4 heme groups, with an iron in each center. The iron(jewel) allows the oxygen to attach to be carried.
Term
Is a hemoglobin (protein making red blood cells) of 9.4 anemic?
Definition
Yes. You are not getting enough oxygen transported to your tissues.
Term
What is Cyanosis?
Definition
Hypoxia, showing bluish color skin. So you are not getting enough oxygen to your tissue.
Term
What is at the center of every heme group?
Definition
Iron (jewel) only this allows for oxygen to then attach.
Term
What three things must be absorbed to make a red blood cell.
Definition
Folic acid, vitamin B12, and IRON.
Term
What does Folic Acid do?
Definition
DNA Synthesis. Basically telling hemoglobulin how to twist and form.
Term
What is the importance of Intrisic Factor. Hint this will be on your exam.
Definition
Produced in stomach juice to bind to B12 to take across stomach wall into blood. Blood then uses this to make red blood cells.
Term
What is the lifespan of a red blood cell?
Definition
120 days. Know 25 trillion red blood cells totalling.
Term
Red blood cells first start as a hemocytoblast?
Definition
True.
Term
What is a Reticulocyte?
Definition
A immature red blood cell that still has organelles. (Red blood cells matured should not have any organelles).
Term
Does a proerythroblast (immature red blood cell) have a nuclei?
Definition
Yes, the nuclei comes from the hemocytoblast.
Term
Does a Normoblast (immature red blood cell) have a nuclei?
Definition
No, after proerythrocyte, they will eject the nuclei to become a (normal) erythrocyte, that has no nuclei or organelles.
Term
Where do red  blood cells go to be degraded?
Definition
The spleen and liver after 120 day lifespan.
Term
How does a phagoctye degrade a old red blood cell.
Definition
They will remove hemeglobulin( protein of amino acids) and splie heme(red portion). Without iron it is now Biliverden(verden-green). Iron is restored in marrow. Biliverden(green) goes to bilirubin(orange) to then go to Bile.
Term
What is the old red blood cells Biliverdin and Bilirubin called in the Small Intestine.
Definition
Stercobilin(brown) bile.
Term
What is polycythemia?
Definition
A high amount of red blood cells, above 45%, meaning sluggish hard blood. However, lots of oxygen transport to tissues.
Term
Platelets are cell fragments from hemocytoblasts that became megakaryocytes?
Definition
True. All cells in general will start from a Hemoblast. (Hint)
Term
Platelets promote clots?
Definition
True, they release serotonin, constricting the vessel to promote less bleeding.
Term
Define Plasma.
Definition
Whole blood minus cells.
Term
Define Serum.
Definition
Plasma (whole blood minus cells) mind clotting proteins.
Term
Serum can clot.
Definition
Falso, has no clotting proteins.
Term
What is the most abundant ion in blood?
Definition
Na. Generally know whats in blood, do not need to know details.
Term
What is the largest protein found in blood? what does it do?
Definition
Albmins , it maintains blood pressure. By increasing concentration in blood more water is being drawn in from the kidneys.
Term
What are gamma globulins?
Definition
Antibodies for immunity.
Term
What are VLDL?
Definition
Transport fat made in liver to fat tissue. Hint high levels are ok to have.
Term
What are LDLS?
Definition
Deliever cholestrol to cells. Hint, high levels are very hard on the heart, and bad to have.
Term
What is the difference between embolism and thrombus?
Definition
Embolism is moving, thrombus is stationary clot.
