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
