NTR 108 Study Guide - Final Guide: Iron-Deficiency Anemia, Low Birth Weight, Perinatal Asphyxia
Document Summary
Platelets (blood clotting) formed by via k and ca. Iron - cation - (2+ & 3+: metabolism - very tightly absorption pathways. Function - component of hemoglobin (in rbc) & myoglobin (in muscle), cofactor for energy metabolism. Active absorption by small intestine - 2 to 35% of eaten. If the body has enough then stored in small intestine & lost in feces. Special proteins: ferritin (stored in form of iron) & transferrin (iron transporter) Fair - tofu (beans), whole grains, dried fruits (dried on iron), leafy green veggies (spinach, parsley) Iron cookware - depends on food acidity-more acid the better. Enriched flour (important because so much is eaten) Neural tube defects (spinal bifida) - malformation of the cns - formed by the 4th week of pregnancy - folate deficiency. Vit b12 deficiency - macrocyclic anemia: very large rbc, fatigue, staggering (neural problem, irreversible) minerals involved in electrolyte balance (na+) - primary extracellular ion.
