Vitamins and Minerals involed in maintains healthy blood
Vit K sources
-bacterial synthesis in gut -green leafy veggies -cabbage type vegetables
Iron Deficiency
-microcytic hypochomic: smaller, lighter red than normal cells -fatigue: tiredness, apathy, decreased concentration, sleeplessness, orneriness
Folacin function
-needed for synthesis of DNA and RNA for PROTEIN SYNTHESIS -helps prevent neural tube defects
B12 functions
-needed for utilization of folic acid (they work together) -needed for nervous system
Factors affecting absorption
1. pregnancy and growth 2.form of iron: -heme: (ferrous) iron in hub best absorbed (meats) -non heme: (ferric) not absorbed as well 3. Acidity in stomach (HCl) 4. vitamin C enhances absorption (meats best sources) 5. bran physic acid, oxalic acid, coffee, panic acid- interferes with iron absorption
vitamins and minerals involved in maintaining healthy blood
B12, folate, iron, vitamin K
Folacin Deficiency
Megaloblastic or macrocytic anemia: large immature RBC
Iron controlled by
absorption -rarely excrete it
B12 deficiency
anemia of folacin deficiency -vegans must be careful
Iron sources
animal products: liver, meat, fish, poultry, eggs, legumes
B12 sources
animal products: meat, fish, poultry, eggs, milk, liver
why do newborns get vit K shots
bc their gut is sterile to start the vit K stores
Vit K function
blood clotting
B12
cobalamin -water soluble
Vit K deficiency
decreased blood clotting
Where is most absorption of iron
duodenum
Vitamin K
fat soluble vitamin (stored in liver)
life of RBC
first: large immature RBC later: small mature RBC
Folacin
folic acid, folate -water soluble vitamin
Iron functions
hemoglobin: transport oxygen to body tissues myaglobin: hold oxygen muscles have a store
anemia
immature RBC or not enough RBC or low hemoglobin
B12 requires an...
intrinsic factor- protein synthesized by stomach and binds to B12 and protects it moving from GI tract to ileum, B12 released from Intrinsic Factor and absorbed in ileum
Where do we store Folacin
liver (even though its water soluble)
where is B12 stored
liver (even though water soluble)
Folacin Sources
liver, mushrooms, leafy green veggies, oranges
blood
major transport system of body, carries nutrients and oxygen
Iron
micromineral
B12 Deficiency
pernicious anemia
2 parts of blood
plasma: mostly water blood cells: RBC
how is iron transported
transferrin: protein that helps transport iron to cells in liver, spleen, bone marrow
how long do RBC last
wear out every 120 days
