Absorbing Food

Actually there are small finger-like projections in the small intestine which helps in absorbing the nutrients from the food material. The small intestine is the part of the stomach that connects to the large intestine. The small intestine consists of an elastic and soft tube which is made up of muscles and membranes, these are tightly contorted in the abdominal cavity.

Cutting down food

When the food is chewed it enters the stomach where the gastric juices make it liquid which can be easy to digest than comes the role of the intestine, liquid food is easier to absorb by the small intestine.  This mixture of food is then pushed forward by the peristaltic movement which contracts from duodenum toward ileum.

These movements are not felt by our body but in the condition of overeating, you will feel the sensation of pain and also in case of food poisoning we will fell pain and spasms. Generally, toxic food causes diarrhea and vomiting due to irritation of the stomach and intestine.

Acidic Characteristic

Let us tell you some more interesting facts about intestine. The stomach contains acid-like chlorhydric acid and some more digestive enzymes which make the food extremely acidic but the small intestine contains bicarbonate and alkaline chemicals which neutralizes the acidity of the food.

These secretions are synthesized by the pancreas, gut’s wall, and liver. The general function of these chemicals is to break down food in small particles which will be easily absorbed by blood and circulate all over the body. The walls of intestines are thin but as they are folded thus there surface is large.

How intestine work

Nutrients that are absorbed from the food go into the blood vessels which are collected by a large vein attached to the liver, from here the nutrients get distributed to different parts of the body but the fat does not pass into the blood, but it passes into the lymph. It also does not pass through the liver.

The large intestine is 5feet long. It consists of six different parts in it such as cecum, ascending colon, and rectum.

Function of the large intestine

The main function of the large intestine is to absorb water from the food material and excrete the solid waste material. Here also peristaltic movement works which pushes the food material rather waste material forward to excrete it out of the body. Usually, the waste material is solid because most of the water is absorbed by the intestine while food material travels through it.

Some more interesting facts about intestine are here like if we imagine small intestine as a simple tube then it will have the surface area of only ½ square meter but due to the presence of small figure like projections which are known as villi its surface area is 200 square meters which can be a size of a tennis court.

Small as well as large intestines consist of muscle in them which are called smooth muscle which helps to move the food through the intestines. The names of these two intestines are according to their width but not according to their length as the length of the small intestine is larger than the large intestine but the large intestine is wider than the small intestine.
