Question

Quizplus · Accepted Answer

The duodenum and jejunum are the primary sites of nutrient absorption, including vitamins and minerals. The ileum primarily absorbs vitamin B12 and bile salts. The colon absorbs water and electrolytes, but not vitamins and minerals. The absorption of vitamins and minerals primarily occurs in the duodenum and jejunum, which are the first two sections of the small intestine where the majority of nutrient absorption takes place. The jejunum absorbs many nutrients more efficiently than the ileum, which is the last part of the small intestine, and the colon's primary function is to reabsorb water and electrolytes. Therefore, A is the best choice as it accurately identifies the parts of the small intestine where vitamin and mineral absorption occurs.
