Question

                           [ Select ]                       ["Increases in pH", "Vasoconstriction", "Vasodilation", "Depletion of manganese"]         increases the resistance to blood flow, through capillaries of                             [ Select ]                       ["the brain", "arterioles", "heart", "the medulla"]         .

When you have a meal, iron is absorbed into                              [ Select ]                       ["tracheal endothelial", "intestinal epithelial", "colonic endothelial", "colonic epithelial"]         cells, where it may be secreted (in the form of ferritin) into the                             [ Select ]                       ["plasma", "lymph", "CSF", "stomach"]         . Because of                            [ Select ]                       ["men's increased muscle mass", "a woman's menstruation", "differences in hormones"]         , the iron requirements of men and women differ.

1. VASOCONSTRICTION increases the resistance to blood flow through capillary of HEART.

2. INTESTINAL EPITHELIUM cell where it may be secreted into PLASMA.

3. Because of WOMEN'S MENSTRUATION the iron requirements differs.
