⩥ What is normal hematocrit readings for males?
Answer: 40 to 54%
⩥ Describe the journey of a red blood cell?
Answer: Iron ingested -> absorbed by small intestine -> transferrin in
plasma transport iron to bone marrow -> bone marrow converts iron to
heme to hemoglobin -> red blood cell synthesis -> 120 days life ->
spleen destroys RBC -> hemoglobin converted to bilirubin -> bilirubin
excreted as urine or feces and iron excess recycled in liver as ferritin or
transferrin.
⩥ How long is the typical life of a healthy red blood cell?
