Explanation / Answer
1). D) The liver becomes less able to detoxify blood.
One of the primary functions of the liver is detoxification. The toxins are metabolized in the liver and converted into inactive products and excreted. This detoxification ability of the liver decreases with age, so there are more chances for the accumulation of toxins. Due to this reason, dose modification of pharmaceuticals is also needed for geriatric patients.
