How long a shower should last depends upon the flow rate of your shower. If you have the hot water turned high, it won't last very long. Typically, the average shower consumes about 15-25 gallons of hot water. Try replacing your shower head with a low-flow type. If your water heater is electric, one of your heating elements might be burned out or you could have a bad thermostat. A plumber should be able to diagnose and correct the problem for you.

The small intestine is the location in the body where the majority of the nutrients from ingested food are absorbed. Whereas the stomach is responsible for the churning and mechanical breakdown of food, the small intestine is very important for absorption.he ileum is preceded by the jejunum. This section of the small intestine is approximately 6 to 12 feet (3.5 meters) long. The ileum absorbs mainly vitamin B12, other water soluble vitamins, bile salts, and nutrients that were not absorbed in the jejunum.
The Absorption of Food by the Human Body. Some nutrients begin breaking down in your mouth. Digestion and absorption begins in your mouth and ends when waste exits your colon. Food is fuel for your body and provides nutrients, which are broken down and absorbed during digestion. Components in foods, including carbohydrates, protein, fat, vitamins and minerals, each have their own function in your system and are metabolized in different ways.
