Q5. Digestion begins in the mouth, where the food is cut and chopped up by your teeth. The tongue helps digest the food with a juice called saliva, which is a secreted by glands in the mouth. Saliva is important because you need it to digest food and it keeps your teeth strong. Q6.…
The circular muscle around the outside of the oesophagus is also smooth. Your swallow forces the food toward the stomach. Step 3. Once it reaches your stomach the cheeseburger is broken down even more, the amylase that went to work on the food in your mouth is taken down by acid.…
• The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called reggae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine. Small intestine: • The small intestine or small bowel is the part of the gastrointestinal tract between the stomach and the large intestine, and is where most of the end absorption of food takes place.…
The process of food moving down to the esophagus is called peristalsis. Peristalsis uses a coat of muscles in the intestines and esophagus. These muscles then therefore calm down and relax and become into a wave motion to let the food pass straight forward. The next…
Food enters through the mouth, and travels via the esophagus. The food goes into the stomach where is broken down in the stomach acids, following through to the first part of the small intestine(duodenum). Then it enters the pancreas,…
The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract. The human digestive system is the organ system responsible for extracting nutrients from consumed food items and absorbing the nutritional molecules into the bloodstream. Doing this requires breaking food into smaller pieces mechanically and chemically, so that nutritional molecules are isolated and can be absorbed. This process involves the help of the muscular system.…
It is it then carried to the stomach through the action of peristalsis (a wavelike motion) so the substance doesn’t fall too quickly. In addition the epiglottis flaps over to…
The digestive system is made up of the digestive tract, the pancreases, liver and the gall bladder. Track refers to hollow organs joined from the mouth all the way to the anus. Food is ingested in the mouth and moves along the digestive tract to the anus where waste is excreted. Along the digestive tract, food is digested and broken down into smaller food components that can be absorbed and utilized by the body. Nerves, blood, bacteria and the organs work together to complete digestion task.…
The study of anatomy and physiology. Anatomy is the scientific term for the study of the body structure and physiology is the term for the study of the function of the body’s organs. During the class, we dissected a pig. We did it to compare the human body and its organ systems with the pig body because they are similar in function. We defined each system and the organs that belong to each one.…
The digestive enzymes lab covers the basic information needed to know to be able to understand the background information of the digestive system. The main function of the digestive system is to break down certain molecules. These molecules must be broken down small enough so that can enter the blood stream. In order for these foods to be broken down three separate digestions must take place.…
Chewing food starts the beginning stages of digestion. From here it goes into the small intestine. As the food passes through the GI tract it mixes with digestive juices causing large molecules to break down into smaller molecules. The small molecules then absorb through the walls of the small…
The digestive system is made up of the alimentary canal which include the mouth or oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines including the accessory organs of digestion which involve the teeth, tongue, salivary glands, liver, gall bladder and the pancreas. The alimentary canal and the accessory organs perform the following functions which include; ingestion, secretion,…
74-75) explained that an integral factor in enzymatic digestion is the pH of individual sections of the digestive tract. The highly acidic pH of the stomach’s gastric juice is needed to not only prevent bacterial growth, but to create an optimal environment for it’s enzymes to digest the food (now chyme) received through the cardioesophageal sphincter. The small intestine cannot handle such high pH, therefore when the stomach releases chyme into the small intestines, a signal is sent to the pancreas to release an alkaline substance called “sodium bicarbonate” to neutralize the chime’s acidic pH. Once neutralized, enzyme-rich pancreatic juices (neutral pH) work together with the enzymes of the cells found in the intestinal wall to facilitate digestion of the “three energy nutrients”. Bile (neutral pH) is secreted into the duodenum from the gallbladder (or liver-if someone is without the gallbladder) to emulsify fat for later absorption.…
Along with the different functions that follow while food is being digested into the body. Among the many things that the digestive system has to offer it also has it’s not so good perks like symptoms & disorders. I have chosen to research about how an infected appendix can affect anybody without a single warning. I will also discuss how it affected a very well-known solo artist and his ordeal behind his Appendicitis.…
The digestive system of a dog is composed of; the mouth, esophagus, stomach, small intestines, and large intestines but also requires help from organs such as the pancreas, and liver. The digestive systems roles are: digesting of food absorbing of nutrients Dog's digestive systems work differently to that of a human, for instance the digestion process begins in the stomach for dog's and in the mouth for humans. It is important for owners to have some idea of how the digestive system works in dog's so they can look out for symptoms that may signal the dog is unwell. The process of digestion begins after the food has passed through the mouth and traveled down the esophagus. The food then enters the stomach, and is broken down…
