The digestive system is made up hollow organs that consists of the mouth, esophagus, stomach, small intestine, large intestine and anus, sequentially. The supplementary organs are the liver, pancreas and the gall bladder.
The food enters first through the (1) MOUTH where mastication or the mechanical breakdown of food particles takes place. After the food is being swallowed it passes through the (2) ESOPHAGUS which is the conduit between the pharynx and (3) STOMACH which secretes acid and enzymes that chemically breaks down food that is termed as chyme. It comprises 10% of the digestion and absorption. The chyme or partially digested food goes to the (4) SMALL INTESTINE where 90% of the digestion and absorption takes place. Its main functions is to absorb the nutrients and minerals from the chyme. (5) The LARGE INTESTINE is where the water from the remaining indigestible food matter is being absorbed. It also transmits the useless waste material from the body where it is excreted through the (6) ANUS

<h3>What is an operon?</h3>
An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule which which is used for the synthesis of multiple proteins.
An example of an operon is lac operon.
