Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication, or chewing, performed by the teeth. The purpose of chewing

We eat all types of food everyday, we have one important tool that we use to break down food which is enzymes. Digestion starts once food is chewed with saliva found in our mouths. Saliva contains all kinds of enzymes and there are hundreds types of enzymes in terms of breaking down food such as amylase,

Once again we have been miniaturized in the submarine to continue the fantastic voyage of the digestive system. We will be touring a 55-year-old male. The host will be having a hamburger, French fries, and a root beer. We will be tracing lunch through the digestion process. Digestion is the process of turning the food that is ate into energy needed to survive and involves creating waste to be eliminated. (Mohan, 2010). The digestive tract is a long twisting tube that starts at the mouth and ends at the anus, called the alimentary canal. The wall of this tube is fashioned of four layers of tissue. The layers are listed from the inside coat to the outside coat: mucosa or mucus membrane, submucosa, muscularis, and serosa. The hollow space

Explain expediency and benefits of their intake and excretionThe digestion of carbohydrate begins in the mouth, and then the salivary gland moistens the food as the food is chewed. The salivary glands have an enzyme called amylase. The amylase is a catalyst that helps in the breakdown of polysaccharides Carbohydrate food. After eating the carbohydrate food into pieces with the help of amylase, it is swallowed to the stomach (chyme) through the oesophagus, at chyme, no digestion takes place. The salivary amylase stops action, and the stomach produces acid that destroys any bacteria. From the stomach, the chyme enters the small intestine (duodenum), the pancreas releases an enzyme called pancreatic amylase that helps in the splitting of polysaccharide into disaccharide. The small intestine t produces maltase, lactase, sucrose. These are enzymes that aids in splitting the disaccharides into monosaccharides.How did the carbohydrate, fats, and proteins differ in digestion process? Explain suitability and benefits of their intake and excretion. (Atoba, MA 1988) The intestinal bacteria help in digesting carbohydrates that refused to digest like other carbohydrates or excreted with faces.Example of carbohydrate foods are bread,Paste,

The digestive system is the process of turning food that we eat into nutrients that the body uses for energy. This system also creates waste that the body needs to eliminate. We are now going to talk about the journey of food through the digestive system to see how everything works together to reserve the nutrients of the food we take in everyday and how the body removes all the remaining substances from our body.

Enzymes, such as amylase, allow the chemical reactions that take place inside the body of a plant, animal, or human. Some enzymes are dedicated to maintaining the immune system where it protects a person against diseases around them such as tobacco smoke. Enzyme is in the diet and contains enzymes in foods that we have digested and are already in the body. “The digestive glands secrete juices containing enzymes that break down nutrients chemically into smaller molecules that are more easily absorbed by the body” (“Enzymes” Science of Everyday Thing). When amylase enters saliva, the procedure of breaking down carbohydrates into sugars begins to occur. Then the stomach will start to produce pepsin, which helps digest proteins while food is in

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

Digestion begins when one sees food. Upon seeing food the brain sends signals for the salivary glands to release saliva. When food is first placed into the mouth by taking a bite it is masticated and broken down to increase the surface area so that food can be digested faster, as well as allowing it to be swallowed. While being masticated food is moistened with saliva, which contains Amylase, which begins the process of breaking down carbohydrates. Once thoroughly chewed saliva forms the food into a clump, which is called a bolus. Once food is chewed and formed into a bolus the tongue pushes the food to the back of the mouth into the throat so that it can be swallowed. Swallowing occurs by reflexes opening and closing the epiglottis, which

The stomach is an expandable muscular sac that is capable of holding 2-4 liters of food and liquids and breaks them down with the use of pepsinogen, an inactive form pepsin, a protein-digesting enzyme. If the stomach was damaged or dysfunctional, then it would be harder to gradually release food into the small intestine at a rate suitable for proper digestion and absorption and to digest the food because it is not as small or digested because the stomach also assists in the mechanical and chemical breakdown of the food as well as the killing of harmful bacteria due to the high acidic environment due to the hydrochloric acid.

Get ready for the dangerous ride of a banana getting crushed, smashed, and absorbed through the digestive system. “Watch out for the involuntary muscles which they can’t even control and voluntary muscles they can control, but will still use thriving to help get our nutrients by crushing us.” everyone has always said but, that didn’t stop him. Once Banana was ripe enough the farmer has picked him. Banana thought is was chosen for an amusement park. because everyone else says it’ll be like a scary rollercoaster, he took it literally…

The challenges for the field of gastroenterology are many in the new environment of the trend toward the accountable care concept, a concept that exposes this specialty to demands for varied and integrated care in a manner which is economically sound for the consumer yet profitable for the physician. These challenges calls for a concerted effort to streamline office procedures and create a more efficient working environment all while attending to the concerns of the practice and remaining a desired, viable, vital specialty. Extensive and continual educational and training requirements pose further demands on the time and resources of the practice, and can cause a profound delay in the optimal outcomes of

You use your mouth to chew your food, causing it to break down in pieces hence using the process of mechanical digestion, and you also use your mouth to form an enzyme known as amylase, or saliva which breaks down your food chemically, for instance when your saliva touches the bread from your sandwich it begins to form into sugars. Incase you did not know “enzymes are chemicals that are used to break down foods into other chemicals”. Saliva can also help you swallow the food by lubricating and “breaking down the complex carbohydrates into simple carbohydrates.”
