,*what category of anemia does anemia caused by ACUTE blood loss fall
under*? - 🧠ANSWER ✔✔NORMOCYTIC & NORMOCHROMIC
*after 5-7 days of getting anemia caused by ACUTE blood loss, what
compensatory mechanism is stimulated*?
what 2 things does this cause to occur? - 🧠ANSWER ✔✔compensatory
*increase in ERYTHROPOIETIN LEVELS*
this stimulates:
1. *RBC production*
2. *reticulocytosis* (immature RBCs)
what is the *main effect of anemia caused by CHRONIC blood loss*?
what are the *4 clinical manifestations that this can lead to*? - 🧠ANSWER
✔✔*IRON STORE DEPLETION*

1. *pallor*
2. *fatigue*
3. *jaundice*
4. *growth retardation*
*what category of anemia does anemia caused by CHRONIC blood loss fall
under*? - 🧠ANSWER ✔✔*MICROCYTIC & HYPOCHROMIC* (since iron
deficient)
what is *iron's role in erythropoiesis*? - 🧠ANSWER ✔✔*necessary for
normal erythropoiesis & hemoglobin synthesis*:
- stored (ferritin) in the liver until needed
- transported to the bone marrow by transferrin (transporter protein)
- iron moves into bone marrow cells, forming part of RBCs (RBCs contain
hemoglobin. heme contains 4 iron capable of binding to oxygen)
