what does blood contain?

ECF (extracellular fluid)

protein molecules (ex: antibodies)

blood hormones

RBC, WBC, and platelets

erythrocyte

red blood cell

where are erythrocytes produced?

red bone marrow

why do erythrocytes have a short life span?

lack a nucleus and mitochondria

what is the fancy term for the shape of erythrocytes?

biconcave

spectrophotometer

an instrument that reads the density of blood samples, finding the glucose and hemoglobin ranges in blood

normal glucose range

70-99 mg/dL blood

pre-diabetic glucose range

100-125 mg/dL blood

diabetic glucose range

126+ mg/dL blood

normal hemoglobin range

12 to 18 g/dL

what is a hematocrit?

separates blood sample into different components

hematocrit equation

hematocrit average range

38% - 48%

hemacytometer slide

a specialized microscope slide that contains a grid pattern

average RBC count

4.5 million - 6 million RBCs/uL blood

-osis

too much

-penia

too little

erythrocytosis

elevated RBC count

erythrocytopenia

deficiency of RBCs

erythropoiesis

production of red blood cells

what causes erythrocytosis?

bone marrow disorders, low O2, blood doping

blood doping

artificially raising RBC count; increases rates of cellular respiration and creation of ATP

why is blood doping dangerous?

leads to blood viscosity and forces heart to work harder, which can cause a heart attack

what should blood doping be used for?

chemo, kidney failure

what causes erythrocytopenia?

anemia
