Pathophysiology Of Homeostasis

The digestive system of a pig is classified as monogastric or non-ruminant, which is having a stomach with only a single compartment, like humans. In addition, the digestive tract of the pig has five main parts, including the mouth, esophagus, stomach, and small and large intestines. Furthermore, the mechanical breakdown of the food begins upon the entrance of the mouth in the digestive tract. Basically, the food is grinded into smaller pieces by its teeth. Next, saliva is produced in the mouth, acting to moisten the small food particles, along with an enzyme that starts the digestion of the starch. Then, the food is pushed towards the esophagus with the help of the tongue. Primarily, the esophagus carries the food from the mouth to the stomach, being a tube, which is carried out with the help of a series of muscle contractions that push the food towards the stomach. Subsequently, after the first of the contractions, swallowing, has taken place, the cardiac valve, located at the end of the esophagus, prevents food from passing from the stomach back to the esophagus. Likewise, the stomach comes next in the digestive tract; it serves as a reaction chamber, adding chemicals to the food. Also, hydrochloric acid and enzymes help break down food into small particles of carbohydrates, protein, and fats. Additionally, some particles are absorbed into the bloodstream, from the stomach, while others cannot be absorbed by the stomach, being passed to the small intestine through the pyloric valve. Moreover, the small intestine aids

The digestive system is a severely underrated part of the human body. For most people, the digestive system is just something that gives them diarrhea after they eat poorly. Little do they know, that the digestive system is the key part to fueling our bodies. The digestive system is how you break down and absorb much needed nutrients. This is how we “fuel” our body. Our body breaks down the food we eat into manageable pieces, and then we are able to absorb it into our bloodstream so that it can be distributed to the rest of the body. In order for this system to succeed in fueling this machine we call our body, all of the parts have to act in unison. If the mouth and stomach can’t break down the food properly, then the small intestine and large intestine are unable to absorbs the proper nutrients to keep the body running. The same goes for the opposite, if the intestines cannot absorb the proper nourishment. Any deficiency in nutrients can lead to many different types of diseases.

In what form are potatoes easiest to digest, raw, cooked, or cooked and cooled? If a potato has been cooked, then it will break down more starch molecules making it easier to digest. The body starts digesting food as soon as it enters the mouth.

The major stages of the digestive system are ingestion, digestion, absorption, and elimination. Ingestion is the process of taking in food and water into the form of swallowing, and digestions is when the food that was consumed begins to breakdown into smaller pieces so it’s easy to be absorbed into the body. Digestion can happen with two phases, when the food is breakdown by teeth and the second phase which is the chemical breakdown, which is the breakdown of food by enzymes. The next stage of the digestive system is absorption, which absorbs the food of the digestions. The nutrients such as amino acids and simple sugars travel in the blood when then goes to the body cells, that can be broken down more or used to build a cell’s large molecule.

Peristalsis is one the most significant mechanical motions of the gastro-intestinal tract. The longitudinal and circular muscle fibres that form part of the oesophagus, stomach, intestines and colon trigger involuntary contractions that are strong enough to propel food matter through their tract. Once the bolus enters the oesophagus peristalsis is the predominant means of mechanically transporting food throughout the remainder of the digestive tract. Peristaltic waves move the bolus through the oesophagus to the stomach, any remaining food in the oesphagus is then propelled by secondary peristaltic waves. ‘One wave travels the full length of the tube in about 9 seconds’ (Britannia.com,2015).

The digestive system is also known as the alimentary canal and is a vast system that is approximately ten meters long. The process of digestion can simply be described as the breaking down of large organic molecules obtained from foods such as carbohydrates, fats and proteins into smaller

The purpose of homeostasis is to maintain a normal balance within the body regarding its temperature, salt concentration, water concentration, and food intake. The human body functions normally with a narrow range of variation for each of these factors. The body has ways of detecting changing levels of these

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). In the mouth is chemical digestion due to the enzymes in the saliva known as amylase (Manley, 83). Peristalsis occurs in the esophagus (phagus = eat) and all throughout the G.I. tract. The smooth muscle tissues contract pushing the food (bolus) down toward the stomach in rhythmic contractions. The epiglottis is a flap that has to close when we eat in order to prevent the food from entering the trachea. At times when we talk or laugh while we eat the epiglottis does not have time to close and we choke (Manley, 83).

For this weeks assignment I chose to write about the mouth. In the case of the digestion system, everything starts in the mouth. The mouth, is where the food in most cases, enters the body and begins to digest. The chunks of food after being in the mouth get chew into smaller chunks, and mix with liquid from the salivary glands and from other food and beverages in order to be swallowed, and to move on down the pharynx. This process is called a bolus. In order to avoid choking the epiglottis shuts the airway, by doing this the food is also able to not enter the lungs.

Homeostasis is the act of mechanisms in the body to keep our body at a constant level.Homostasis can take part in many ways such as regulation of salt, osmoregulation, oxygen and carbon dioxide and many more. Receptor cells allows the control center (usually the brain) to detect a change .The process in the body is affected by homeostasis.

The gastrointestinal system allows for an intake of substance and extracts the nutrients from the food. The substance that is not absorbed by the body is then expelled as waste (Wallace 2013). The Gastrointestinal System starts at the mouth primarily with mechanical digestion. It then follows a hollow tube called the esophagus, which serves as a connecter into the stomach. The stomach continues to mechanically churn the bolus, but also takes part in the chemical breakdown of proteins (Bolus 2016). From the stomach the chyme enters into the small intestine. The small intestine is comprised of three sections: the duodenum, jejunum, and ileum. The small intestine is important for breaking down carbohydrates and fats, but also begins to absorb the nutrients for the body (Gastrointestinal tract 2013). Whatever is not absorbed by the small intestine then moves to the large intestine, where vitamins and water are absorbed. The large intestine is made up of the cecum, colon, and rectum to finally be passed out through the anus (SEER 2016). All wastes are then expelled out of the body.

Digestion is the process of breaking down food into a form your body can use. The digestion process begins in the mouth. Chewing mechanically breaks down food into small pieces while saliva mixes with the food to create a soft, moist mass of food for swallowing called a bolus. Saliva contains enzymes that chemically breaks down carbohydrates. When the bolus is swallowed, it enters the esophagus. Peristalsis, synchronized waves of muscle movement throughout the digestive system, moves the bolus toward the stomach. When the bolus nears the end of the esophagus, pressure from the food signals the muscle at the end of the esophagus to open and the bolus enters the stomach. In the stomach, the bolus is churned by the powerful muscles of

Homeostasis is the phenomenon which is achieved in the human body to maintain a stable and constant internal environment. It is an automatic process which will protect and guard the levels of water and oxygen in the blood, salt, hydration, and temperature in the body to direct and manage them. Bodily systems need to maintain homeostasis because the circulatory system is crucial to the internal environment in that tissue fluid sustains small molecule movement across capillary walls. The digestive system dispenses nutrients to the blood, whereas the excretory system removes waste. Oxygen is taken in and carbon dioxide is excreted in the respiratory

It begins in your mouth where you use your teeth to break down the food you eat into smaller pieces. Your salivary glands release a watery liquid to bind the food into a bolus making it easier for the food to slide down the esophagus. Next the tongues pushes the food upwards and back towards to the palate, occurring rapidly without interruption. Whole swallowing the tongue pushes the food down through the muscular valve called the upper esophageal sphincter, which allows

The gut or the gastrointestinal tract is our digestive system, located inside the body. The digestive system is working round the clock to absorb nutrients from the ingested food, process it and then expel the waste products out of the body. It comprises of mouth, esophagus, small intestine (small bowl) and colon (large bowel or the large intestine). The process of digestion begins in the mouth itself. The movement of food from one part of the intestine to another is called as a bowel movement.
