Term
Transportation system, Heat Regulation, Immunity, Storage Site
Definition
State 4 general functions of blood.
Term
glucose (sugar), amino acids, fatty acids, nucleic acids, salts, vitamins, hormones, oxygen, water
Definition
State 4 "good" things blood carries to cells.
Term
ammonia, CO2, urea, H+, toxins, lactic acid
Definition
State 3 bad things blood takes away from cells.
Term
Plasma, WBC's and platelets, and RBC's
Definition
Blood splits into 3 layers when centrifuged. What are they?
Term
5 liters
Definition
How much blood does the average person have?
Term
Tissue demand. If a tissue is active and using lots of nutrients, the blood will be directed to it.
Definition
What determines where blood is delivered in the body?
Term
proteins, minerals, ions, nutrients (sugar, amino acids,. . ), hormones, vitamins, wastes
Definition
What types of things would be found in plasma?
Term
Fibrinogen
Definition
A protein that is stored in the blood that causes blood to clot.
Term
Gamma globulins
Definition
Proteins stored in blood that are antibodies to fight infection.
Term
Biconcave disk-
It allows them to be more flexible through tiny capillaries and it increases the surface area for holding gases.
Definition
What shape do blood cells have and why do they have that shape?
Term
Hemoglobin
Definition
What is the pigment molecule in RBC's that binds the O2 and CO2?
Term
Iron and Vit. B12
Definition
What nutrients from our diet are necessary to build healthy RBC's?
Term
Nucleus
Definition
What are RBC's missing that other cells have?
Term
120 days
Definition
How long do RBC's live?
Term
25 trillion
Definition
How many RBC's are in the body?
Term
Kidney and Liver
Definition
What two organs monitor blood O2 levels?
Term
erythropoietin
Definition
What is the hormone that targets red bone marrow to make blood cells?
Term
Kidney and liver
Definition
Where is erythropoietin produced?
Term
liver and spleen
Definition
What two organs monitor the health of the RBC's and destroy them when they're old?
Term
All of them b/c they all originate from the same stem cell in the bone marrow.
Definition
If stems cells in the bone marrow were damaged from radiation, which blood component would not be made correctly?
Term
Anemia
Definition
What do we call disorders/ diseases caused by defective RBC's?
Term
They don't have a nucleus?
Definition
Why can't RBC's do mitosis or cell division when they get old or damaged?
Term
Macrophages in the spleen and liver
Definition
What cells phagocytize (eat) the RBC's ?
Term
The decomposed products are recycled mostly. We reuse the heme and iron to build new RBC's
Definition
What happens to the phagocytized RBC's?
Term
hematopoiesis or erythropoiesis
Definition
What do we call the formation of blood?
Term
erythrocyte
Definition
What is the name of a RBC?
Term
Oxygenated Hemoglobin is bound to many O2 molecules and it appears scarlet red.
Deoxygenated HB is missing O2 and looks maroonish.
Definition
How is oxygenated hemoglobin different from deoxygenated hemoglobin?
Term
Sickle Cell Anemia
Definition
What disease is genetic and causes people's blood to be crescent moon shaped?
Term
liver, spleen and yolk sac
Definition
Where is blood made in a fetus?
Term
They are torn as they pass through the tiny capillaries.
Definition
How are RBC's damaged?
