Q

Haephestin

A

Possibly oxidizes Fe2+ into Fe3+ on the basolateral side of the duodenal epithelium, so that the Fe3+ can bind to plasma apotransferrin

Q

What factors affect iron uptake in the duodenum?

A

Proteins and amino acids (increase absorption)
Vitamin C (increase absoprtion)
Phytates and Oxalates (components of food) (decrease absorption)

25
Q

Transferrin

A

iron transport molecule in the circulation

26
Q

Ferritin

A

Iron storage molecule, found intracellularly in splenic macrophages

27
Q

Hepcidin

A

protein made in the liver in response to high iron uptake, inflammation, and infection. When increased, it slows uptake of iron, decreases plasma transferrin iron concentration, and decreases RBC production. This mechanism is disrupted in anemia and hypoxia. When upregulated, it degrades ferroportin, increasing intracellular iron stores and also ferritin bound iron

28
Q

Erythrocyte concentration in blood

A

~5E6 per uL of blood

29
Q

Platelet concentration in blood

A

150-400,000 per uL of blood

30
Q

White Blood Cell concentration in blood

A

4,500-10,500 per uL of blood

31
Q

Neutrophil % in differential

32
Q

Eosinophil % in differential

33
Q

Basophil % in differential

34
Q

Monocyte % in differential

35
Q

Lymphocyte % in differential

36
Q

Intrinsic Factor (IF)

A

Secreted by the GI tract, binds to Vitamin B12

37
Q

Pernicious anemia

A

Vitamin B12 deficiency anemia, caused by the autoimmune destruction of the gastric parietal cells that secrete intrinsic factor (IF)
