The digestive system is a 9 meter long tube that breaks down food starting in the mouth. It’s first chewed (mechanical digestion) then is swallowed down the throat and enters the stomach. The food in the stomach is mixed with mild acids (chemical digestion) then is made into a paste that slowly progresses’ into the small intestine. Foods that cannot be broken down further in the small intestine then exit through the large intestine out of the body. The digestive system is very important because without it there is no other way the food could be broken down and made into energy and digested, which every human needs to survive.
Food enters the mouth. In the mouth the food is chewed and mixed with saliva that starts to break the food down. The food goes down the throat and the esophagus into the stomach. In the stomach, stomach acid and the food mixes and breaks down into smaller particles then it goes in the small intestine. In the liver, bile is made and stored in the gallbladder. Bile digests the fats we eat when it is released in the small intestine. Secretions from the pancreas also help digest food in the small intestine. The small intestine stretched out would be as long as a football field. The food is further broken down in the small intestine so it can be absorbed through the lining of the intestine into the bloodstream to travel to the cells. The leftovers or waste from the small intestine go to the large intestine where water is absorbed into the body and feces is formed. The feces goes into the rectum to be stored until it is released through the anus.
One of the organs in the digestive system is the stomach. The stomach is an organ because it is made up of many different tissues. One of the tissues is epithelial tissue, and epithelial tissue is made up epithelial cells. Another example is the kidneys. Inside the kidneys, there is muscular tissue, which is made out of muscle cells.
Eat Healthy: Eating healthy is key in maintaining a healthy digestive system. Foods that are high in fiber such as fruits and whole grains can easily pass and be digested through the digestive system. Also be cautions about how much fat you are consuming. High fat content in your diet can be harmful to your digestive system and may cause aggravate diseases and also heart disease. Be sure to drink lots of water. When you drink water it breaks down nutrients and helps the passage of wastes
Eat slowly, regularly and moderately: To avoid putting to much stress on your digestive system try to not eat large portions at a time, have a plan with what you are going to eat at meal and snack time. When you are chewing food don’t rush it, relax and take a while to chew to make sure food is broken down properly.
Physical activity: Exercising regularly decreases sluggishness. When you exercise you strengthen your abdominal muscles which helps contents push through your digestive system smoothly.
Reduce Stress: When people are Stressed it effects the nerves of the digestive system and can confuse the digestive system. When stress levels are high in some people it can slow the process of digestion, cause bloating, pain and constipation.
An adult stomach can hold
about 1.5 litres of material
Cooking destroys food enzymes, forcing the body to make is own, which can cause possible indigestion.
We produce about 1.7 litres of saliva each day.
In the mouth, food is either cooled or warmed to a more suitable temperature.
The esophagus is approximately 25cm long.
