When that hump is empty, it loses its firm shape and flops to one side . The purpose of the hump is to serve as a storage place for food.

In the second stomach are the digestive juices and in the third the chewed cud is digested.
In the walls of the first two stomachs, there are pockets for storing water.
Muscles holds these pockets closed when they are full.

and close to let out as much water as it needs. If a camel
travels slowly and with a light load, the water in its stomach
can last anything from six to ten days

How does my memory work
Memory in the ability to store things that you experience and learn, ready for use in the future. Some things are remembered easily, such as dramatic events in our life. However, more ordinary things need to be rehearsed in the mind several times before the 'stick'. There are three
different ways of storing memory. Sensory memory , which
is very brief. tells you what is happening around you and
allows yo to move without bumping into things. Short-term
memory, which lasts for only about 30 seconds, and allows you to remember a phone number and dial it, but after a
minute or so it will vanish. Finally long-term memory, for
things that you have carefully memorized and learned.
