red blood cells, white blood cells and platelets
where are the formed elements of blood produced in?
bone marrow
What is the process of formation of blood cells
hematopoiesis
What is the basic foundation of blood?
Plasma which is chiefly made of water
What are erythrocytes?
red blood cells
What gives blood its dark, red color?
red blood cells
what’s main function is to deliver oxygen to the body and remove waste products?
RBC
What is it when hemoglobin binds with oxygen called
oxyhemoglobin
what does red blood cells contain millions of molecules of
hemoglobin
what is the process of generating red blood cells in the bone marrow called
erythropoiesis
When does the the spleen and liver destroy rbs?
after 120 days
White blood cells are called what?
leukocytes
What is the main function of WBC’s
defend against infection and foreign invaders
what is an increase in the WBC count indicator?
an infection
What are the two types of WBC?
granulocytes and agranulocytes
Which WBC cells have a granular apperance?
granulocytes
What are the type of granulocytes in WBC?
neutrophils, eosinophils, and basophils
what are neurtrophils?
Cells that respond to bacterial infections such as pneumonia or urinary tract infections by eating the bacteria
What are eosinophils in WBC granulocytes?
involced in allergic reactions to food or drugs. help fight infections by parasites
Basophils
they are involved in process of inflammaiton
Agranulocytes
do not have a granul apperance
What are two types of agranulocytes?
lymphocytes and monocytes
what do lympocytes produce
antibodies against foreign particles such as microorganism, drugs, cancerous cells and cells form transplanted organs
what are monocytes?
phagocytic cells, main functions is to eat other cells and pathogens
What are platelets also known as
thrombocytes
What are thrombocytes
the cells that act as a plug to a cut, and stops it from continuing bleeding out
how much of plasma is water?
92%
what are the most important proteins in plasma?
fibrinogen, albumin, and globulin
In plasma, what is the protein that is bloodclotting made in liver
fibrinogen
what protein in plasma made in liver, and maintains pressure needed to pull water from tissues back into blood vessels
albumin
what protein in plasma are formed in liver and lymph system and can be found in diff forms in plasma, helps form antibodies, and blood coagulaiton
globulin
what is the term for blood clottin
coagulation
what is a drug that promotes coagulation
pro coagulation
what is a substance that inhibits coagulation
anti coagulant
How is blood type defined?
by genetic markers and blood proteins called agglutinogen
what is agglutinogen
the antigen on the surface of red blood cells
which blood disorders can be severe
in bone marrow
what is define as low RBC
anemia
Which disorders can be caused by blood loss, destruction of the RBC, or inadequate blood cell production
anemia
Who are people who often pale, weak, shortness of breath, and low enegery
anemia

dificiency in vitamin B12 and folic acid
What can anemia be also caused by
kidney disease, cancer and HIV
what hormone is producted in the kidneys and stimulates rbc production
erythropoietin
which anemia is a result of decreased rbc survival time due to excessive hemolysis or destruction of rbc
hemolytic anemia
yellowing of the skin is a sign of hemolytic anemia
jaundice
what anemia is caused by condition of the bone marrow known as aplasia
aplastic anemia
What anemia, is it when the bone marrow cells fail to develop.
aplastic anemia
what treatment is used when infections cause increase of wbc?
antibiotics
a form of wbc disorder
cancer
what is neuropenia
the decreased neurophil count
what can neutropenia cause
increase risk in infections due to neutrophils defending foreign pathogens
what is the disorder that bone marrow produces an extreme abundance of wbc
leukemia
what occurs in leukemia
when the production of wbc goes unchecked and can destroy other blood cells
