We all have to eat food to survive when the average person eat food we don’t think about all the things your body have to do just to digest what we ate this short essay I will explain to you the process of how we digest food. Digestion times vary between people but on the average it takes 24-72 hours for our body’s to digest food. The first process with digestion is ingestion which means the chewing process while we chew food it’s broken up in the mouth with saliva and forms into a ball for swallowing called bolus the amylase in our saliva starts to breakdown starches and simple sugar from there the food go down the esophagus to the stomach. When your food hit your stomach hydrochloric acid breaks the food down more turning the food into chyme once this process is over the chyme is released into our small intestines a little at a time. When the chyme hit the small intestine this starts the real digestion process the pancreas, gall bladder and duodenum release digestive enzymes to break down the food even more and turn it into a chemical component and the chemical elements of the food are absorbed in our blood stream this process alone can take up to 6 hours. When the food leaves the small intestine it moves to the large intestine water and minerals are removed from the chyme making it solid so it can turn into fecal matter and it prepares the body to get ready for elimination the colon is approximately 5-6 feet long and it could take 30-40 hours for food to pass through. This is the entire process of food going through our body daily some foods are different and can be processed before others because our digestive system digest at different rates for different foods most carbohydrates process faster and is eliminated first.

The process of digestion has many stages with the first starting in the oral cavity. Within the system, food passes through a tube called the alimentary canal, more commonly known as the gastrointestinal tract. The tract is made up of the oral cavity, pharynx, oesophagus, stomach, small intestines, and large intestines. To provide energy and nutrients to the body, major functions take place in the digestive system which include; ingestion, secretion, mixing and movement, digestion, absorption and excretion.…

The digestive system is the physical ad chemical breakdown of food. Following ingestion, food and fluids are processed by the digestive organs so that nutrients can be absorbed from the intestines and circulated around the body. Any residue of food that is not digested is solidified and eliminated from the body in the form of feces. (P.207)…

The digestive system is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After food is chewed and swallowed, it goes down the esophagus and enters the stomach, where it is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesn't need or can't digest is turned into waste and is eliminated from the body.…

The Digestive System is the name given to the sequential process that our bodies perform when ingesting food, and the breaking down of macromolecules into micromolecules so that the body can absorb it’s nutrients into the bloodstream and it’s cellular system to obtain energy for cellular respiration, and the excretion all indigestible waste products. This happens within the digestive tract, which starts at the Mouth or Oral cavity and ends at the Anus. (Reference Appended image 1,’ The Human digestive system and associated organs). The molecules of food that we eat are generally Polymers, i.e., large, complex Molecules that are composed of long chains of Monomers. Polymers are insoluble and therefore cannot be absorbed into our bloodstream and need to be assimilated into different absorptive products. Polymers have to be hydrolysed into smaller, soluble molecules. This process happens during the process of digestion. Food is broken down by mechanical or chemical means (Hydrolysis) and this process is aided by Enzymes. Enzymes are biological, process catalysing Proteins which massively speed up the breaking down of compound molecules into micromolecules to allow nutritional absorption. All digestive Enzymes are Hydrolytic, i.e., a water molecule is added to allow compound molecular breakdown and separation. All Enzymes have a unique shape to their ‘active site’ allowing only the target substrate to bond for biological processing. Enzymes have optimum operating requirements and can denature if the temperature becomes too warm or the environment too acidic or alkaline. Digestive Enzyme secretion is regulated by both the nervous and the hormonal systems. Hormones are a chemical substance signalling system that communicates from one set of cells to another set, the target cells, which will then trigger enzyme secretion.…

As most of us know the digestive process begins as soon as food enters into our mouth. Saliva begins to break down sugars and starches, while our teeth grind the food into what is called bolus. The bolus enters into the esophagus and is than swallowed. From here it than enters into the stomach for further breakdown from stomach acids. Very little food is actually digested in the stomach. It is just broke down a little so that it can be easier for the digestive process that will take place in the intestines. Our food starts to break down into a thick paste known as chyme, it moves past the pyloric sphincter and into the small intestine. The pyloric sphincter is what protects food from re-entering into the stomach.…

The way that the digestive system works is pretty simple to remember. First you bite on something eatable, then the enzymes in your saliva start digesting the carbohydrates. Once the food bits are in your stomach, they are drowned in gastric juice, which is made up of the enzyme called pepsin and a acid called hydrochloric acid . The enzyme and the acid start to break down the food and by doing that, nutrients are released. Digested food then from the stomach is pumped into the small intestine, which the gets flooded by fluids and enzymes from the liver , or better know as the bile , and from the pancreas.…

The beginning of the digestive process starts with the smell and sight of food which activate the salivary glands. The mouth is the point at which food enters the digestive tract and continues the digestive process by chewing food. The food is then broken down into pieces and moistened by salivary glands which turn food into a bolus. The bolus goes down the pharynx into the esophagus which connects the pharynx to the stomach. The stomach is an organ that mixes food and secretes gastric juice. The bolus, once in the stomach, is mixed into a semiliquid mass called chime. The stomach is close together with the liver and pancreas but does not get assistance from these organs. The chime then enters…

The digestive process starts with saliva. Saliva begins with the scent or sight of food. Food enters the digestive system starting at the mouth. Food is broken into smaller pieces by your teeth. The broken up pieces of food mix with saliva and break down into a substance called bolus, which is a ball of chewed food. Bolus then passes through the pharynx, which helps us swallow, into the esophagus and into the stomach. The stomach further breaks down the bolus with highly acidic stomach secretion and is turned into a semi liquid mass called chyme. This process could take 2 to 6 hours depending on the amount of food and type of food. The chyme then moves to the small intestine. The small intestine is 20 feet long and takes 3 to 5 hours for chyme to move through the small intestine. This is where most of the nutrients are absorbed. While moving through the small intestine additional secretions are produced from the liver, gallbladder and pancreas to assist in the digestive process. The chyme that is not absorbed is then deposited into the large intestine through a sphincter. The sphincter prevents any substances from reentering the small intestine. The large intestine is 5 feet long and the break down process can take 24 hours. The large intestine is the last chance to absorb any leftover nutrients. As chyme travels through the colon some left over water, vitamins and minerals are absorbed. Any substances left are moved to the rectum and stored until it moves to the anus for…
