Quizplus · Accepted Answer

The nervous,cardiovascular,and gastrointestinal tract can all be affected by thiamin deficiency.The central nervous system depends on glucose for energy; if thiamin is not present in adequate amounts,sufficient energy cannot be made for the nerves to perform their functions.The heart muscle depends on thiamin as well.Without adequate thiamin,the heart muscle weakens and heart failure results.Thiamin also is necessary for the gastrointestinal tract to function properly.The cells of smooth muscle and secretory glands must have energy to perform their work,and thiamin is a necessary agent for producing that energy.
