The Digestive System are organs that work together to make food into energy. So the basic nutrient enters the body. There are six major functions of the Digestive System:1. Ingestion of food:
When you eat and then you swallo the food. The stomach are responsible for the storage of food and waiting to be digested.
Interesting fact: storage capacity allow your body to eat a few times each day and injestion more food than it can process at one time.
2.Secretion of fluids and digestive enzymes:
Our digestive systems fluids knows as saliva, mucus, hydrochloric acid, enzymes and bile. Saliva- This fluids have their own functions Saliva contains salivary amylase that moistens our food. Mucus- found inside the Gastro intestinal tract that is like an oil used to protective barriers.
Hydrochloric acid- Is so amazing that protects our body killing bacterias that may be found in food. Enzymes- Small biochemical machines that break down large macromolecules for example protiens, carbohydrates in their smaller form. Bile- changes a large volume of lipids into tiny droplets that are easy to digest.
3.Mixing and movement of food and wastes through the body:
their are three main processes Swallowing is the process of the smooth and skeletal muscles in the mouth, tongue, and pharynx to push food out of the mouth, through the pharynx, and into the esophagus. Peristalsis is a muscular wave that travels the length of the GI tract, moving partially digested food a short distance down the tract. Segmentation occurs only in the small intestine as short segments of intestine contract like hands squeezing a toothpaste tube.
4.Digestion of food into smaller pieces:
This breakdown of large pieces of food to smaller pieces. A process that starts when we eat our food and goes down to our stomach and intestines.
The process is a chemical method breaking down large molecules to smaller ones. Our pancreas secretes strong digestive fluidl known as pancreatic juice, which is capable of digesting lipids, carbohydrates, proteins and nucleic acids. When the food duodenum its been reduced to its chemical building blocks—fatty acids, amino acids, monosaccharides, and nucleotides.
5.Absorption of nutrients:
This absorption process starts in our stomach with simple molecules like water. Plus our bloodstream directly absorbs alcohol which is another starting process. The wall of our small intestines is where most of the absorptions takes place. At this wall is whee our food is digest in our system.
Lymphatic vessels in out intestinal wall will carry the rest of the
Small blood and lymphatic vessels in the intestinal wall pick up the body. Feces will leave our body through the large intestins once water , vitamins B&K are absorbed.
6.Excretion of wastes:
Defecation is the final process that waste is excreted from our digestive system. This phase anything that is indigestible so it doesn't stay inside our stomach. This is a voluntary action that is controlled by our brain.
