Villi of the small intestine shorten and widen with age and,as a result,become less functional,which contributes to malabsorption of nutrients; despite a healthy diet,nutrients are absorbed primarily in the small intestines.The concept of malabsorption is what the nurse uses to plan care; this nursing diagnosis refers to the inability of the body to absorb nutrients as a result of biological factors.Decreased intrinsic factor secretion leads to pernicious anemia as a result of the inability to absorb vitamin B?? in the stomach.Gastric smooth muscle is not present in the intestines.Decreased large intestine motility is an age-associated problem; however,it should have no impact on absorption in the small intestine.
