However the main function of the small intestine is the absorption of the small food particles resulting from digestion. It contains many villi which increase the surface area for absorption. The large intestine moves the material that has not been digested from the small intestine and absorbs water.
Respiratory failure caused by botulism can result in death. About 50 years ago half of all patients with botulism died, compared to just 8% today. Patients with severe symptoms may need a breathing machine, intensive medical and nursing care for several months. Fatigue and shortness of breath may linger for many years.
Botulism is a serious illness that causes paralysis or muscle weakness, including weakness in muscles needed for breathing. It is caused by a poisonous nerve toxin released by bacteria named Clostridium botulinum. Most of the time, botulism bacteria live in an inactive form called spores. Inactive botulism spores are found widely in soil, dust, and honey. A hard coating helps the spores survive heat, drying, and radiation for long periods of time.
