...Checkpoint: Reflections on Nutrition As I reflect on what I have learned about science nutrition, using the assignments that I have completed up to this point as a reference I would say that now I understand how the body transforms everything from cheeseburgers to vegetables into energy that we can use and need to operate daily functions of the body. I have also learned how changes such as aging, illnesses, and exercise can affect the body’s digestion process and growth process. The chapter in the textbook has introduced me to the latest research and the benefits and possible dangers of antioxidants. The assignment: Healthy Eating Plan Comparison and the assignment: Three Day Activity Analysis has influenced me to become more aware than ever that food is my body's main fuel source. Which means the nutrients in food gives my body's cells the energy and other substances it needs to operate that is why I need to be very mindful as to what I put in my body. I understand the digestion process and why it such a vital part the body. The digestion process breaks down the nutrients into the simplest forms so the body can metabolize the necessary vitamins, proteins, carbohydrates, fats, sugars. I think without digestion the body could not use the food in the form it is ingested. I am now very conscious of the common digestive problems and ways to alleviate them. If I had to choose one assignment that I enjoyed the most it would be the Checkpoint: Nutrition Needs Presentation because...

...This is where the digestion first begins when the food is chewed and swallowed. The esophageal and cardiac sphincter contract and migrate the food down to the stomach. The sphincter aid in preventing reflux of food back to the mouth. The stomach muscles turn and mix the bolus with the gastric juices. The small intestine work with its two layers of muscles in removing and absorbing all the minerals, nutrients, and vitamins from the bolus. The large intestine contract and expand to move the mass to its final destination and is expelled through the anus. (Understanding Nutrition,...

...Metabolism Assignment 1 - 15% of final marks How does the digestion system of your chosen animal break down food i.e. conversion of food protein to animal protein? Nutrition and Metabolism of the Cow: Digestive System of the Cow. Proper nutrition is the foundation for a productive and profitable cow herd. Unaccompanied with good nutrition, cattle can’t express their full potential including reproductive efficiency. Cattle are classed as ruminants, they have four compartments to their stomach and chew their cud. The cattle digestive system evolved to be able to handle large volumes of material. Dairy farming is a crucial part to Australia’s rural industry. On farm efficiency is on an increase through the improvement of pasture and feed and also herd management techniques. Supplement the cattle diet with grains and other legumes is becoming increasingly common, the Australia’s dairy industry remains predominantly pasture based. State’s of Australia, Victoria foremost, have attainable milk productions, supplying fresh milk to nearby cities and towns. The industrial value increases through the processing of milk to produce fresh lines such as butter, cream, cheese and yogurt. Bulk milk and specialised powdered milks are also significant. (Crampton, E.W, Harris, L.E (1969) “A Series of Books in Agricultural Science - Animal Science” (W.H Freeman and Company - San Francisco)) Cattle feed can be classed as either roughages (high fibre plants / the fibrous part...

...Digestive system P2 The Digestive system is a bodily system that converts food into energy, nutrients and cells for the repair of the body. The digestive system consists of a number of organs; the Stomach, Liver, Gallbladder, Pancreas, small Intestine, large Intestine and many more. Digestions Digestion is the process that turns food into its component chemicals. This starts off with mechanical digestion, this is the physical breakdown of big pieces of food into smaller pieces, chewing in your mouth then continues with the mixing of the muscular organs stomach and small intestines. At the same time chemical digestion is occurring, this breaks down more larger, complex molecules into smaller molecules that are easier to absorb. Chemical digestion also started from the chewing process in the mouth where food is mixed with saliva, saliva splits complex carbohydrates to simple carbohydrates. It continues in the stomach with enzymes and acid but the rest happens in the small intestines. The pancreas produces pancreatic juice that has digestive enzymes that break down complex molecules like fats and proteins. Absorption...

... Human Digestive SCI/241 Nutrition November 22, 2012 Mr. Brain Oddi By: Lenicia Ridley The Human Digestive System Human Digestion 1. How long does it take for food to go through the digestive system? Salivary glands begin the digestive process at the sight and smell of food. After, food enter the mouth and is moistened by, saliva and chewed by the teeth, it transforms into a bolus. Once the bolus leaves the mouth, it moves into the pharynx where it can be swallowed. The bolus then moves from the pharynx into the esophagus, which connects the pharynx to the stomach. Once the bolus reaches the stomach, it is mixed with acid secretions to transform the bolus into chime, a semiliquid food mass. Food is partially digested into the stomach, and chime usually empties from the stomach in 2 to 6 hours. This timeframe is determined by the size and type of meal ingested. 2. How does digestion occur in each of the following parts of the digestive system? Digestive system occurs in the mouth through salivary glands at sight...

Parotid Salivary Gland- These glands are found under and behind the tongue and beneath the jaw as well. The way I will remember this is because the middle word reminds of me Saliva so I know the gland is mostly where your saliva is at. 2. Pharynx- The pharynx is basically located in your throat. I’ll remember this because it is located in your throat and I know it will be right before the Esophagus 3. Esophagus- This is a long tube that is right after the pharynx and passes through your chest and into your stomach. I will remember this because of the long tube I will always remember that it is after the pharynx. 4. Stomach-The stomach, known as the “pouch-like organ”, makes sure to store the food as well as to mix up and churn the nutrients from the food. It is located on the right hand side of the liver right after the Esophagus. I will remember the stomach because I know it is attached right after the esophagus and it looks like a pouch. 5. Liver- The liver is located to the left of the stomach right after the Esophagus. I will remember the liver because I will know that this is one of the first organs that pop up in our body on the left hand side. 6. Pancreas-The pancreas is located right under the liver really small...

...P2 There are many nutrients that are required for a balanced, healthy diet, five of which are: carbohydrates, proteins, lipids, vitamins and minerals. Carbohydrates: Carbohydrates is a micronutrient, alongside fat and protein which all provide us with energy quickly. A carbohydrate is a sugar and is composed of hydrogen, carbon and oxygen. It helps digestion and provides energy. Carbohydrates are divided into 3 groups: starch, fibre and sugar, which all help digestion. Protein: Protein is found in foods such as eggs, meat, fish and cheese. A source of protein is formed when a group of amino acids are joined together in chains. Each chain is called a polypeptide, eight of them come from the different foods mentioned previously. In terms of its...

...Esophagus. The esophagus secretes mucus and transports the food to the stomach via peristalsis. C.) Why might reduction of the side of Chloe’s stomach reduce her acid reflux? Her stomach will not hold much food, so the acid produced will be reduced. With part of her stomach stapled, there are less gastric glands that produce the acid. Also the pressure on the valve at the top of her stomach, the lower esophageal sphincter is reduced. D.) How will protein digestion be affected by Chloe’s surgery? The digestive process is altered. The stomach does not produce as much acid. Acid is necessary to denature protein. RNYers may have difficulty breaking protein down into its constituent amino acids. Protein cannot be absorbed whole; it can only be absorbed in amino acid form. Hydrochloric acid, pepsinogen, and normal churning can be reduced or eliminated. The pancreatic enzymes that would aide in normal protein digestion are redirected. E.) Which pancreatic enzymes would Chloe need to break down the fats in her nutrition drink? The enzyme that the body uses to break down fat is lipase. This splits fatty acids from triglycerides and phospholipids. CHLOE’S STORY 2 F.) Why might Chloe be at risk for gallstones (crystallized cholesterol which can block the flow of bile from the gallbladder)? Do to the increased weight loss so fast, the bile was already stored from her high fat diet that she was eating...

...iLab week 1 Essay SCI 228 Nutrition, Health, and Wellness iLab Week 1 Essay There are 14 parts of the digestive system. They include the salivary glands, tongue, pharynx, esophagus, stomach, liver, pancreas, gall bladder, small intestine, large intestine, appendix, rectum, and the anus. Food we eat first enters our mouth, which is where you find the tongue. We know it’s in there because it tastes the food we put in our mouth. You will find the salivary glands in 2 spots, under your tongue and behind your tongue. The best way to remember that it’s located there is to known that it releases saliva and there is always saliva on your tongue. Our pharynx is found in the back of the mouth. To remember it is located there I use the first half of the word which sounds like far, and then use that as a saying. The Pharynx is the start of a far travel. This is down the esophagus. The esophagus starts at the back of your mouth and runs down into your stomach. I remember it’s located there because I feel food go down my esophagus when I touch my neck. Our stomach is located underneath our heart. Most people love food. I use that to remember where our food goes after we swallow, under the heart into the stomach. The pancreas is located behind the stomach. It’s located behind the stomach because it needs to use the blood streams coming out of the heart to add enzymes it made. After the stomach, food will go into the small intestine. The best way to remember that the small intestine...

...Reflections on Nutrition SCI/241 4/4/2011 Summer Groff Week 9 Checkpoint Reflecting on what I have studied so far on nutrition, using my assignments completed up until this point is that I have come to the knowledge of how the human body works from the moment food enters the mouth through digestion and coming out as waste. I have also obtained knowledge about how the body changes through aging, and how diet and exercise can actually help the body’s digestion and growth process. I have learned through doing research throughout my course on nutrition, which has helped me gained understanding on what to do to stay healthy as I age. The assignment that I enjoyed throughout this class is the three day activity analysis. After completing the analysis I became aware of what I was eating and made me aware that food is the body’s main source of fuel, which means that nutrients in food gives the body cells energy to function. I am now cautious and made changes of what I eat. Making healthy decisions and adding daily exercise to my life style has improved my health. Another assignment I enjoyed was week 5 on dehydration. I learned much about the importance of water and how the body needs water to function adequately. Water washes away and cleanse out toxins, it also assists the cell functioning, and is the primary aid of the ear, nose and throat functioning. Water also bathes the cells in the body and serves as a lubricant; it cleanses both external and internal surface...
