Nutrition involves vitamins like vitamin A, B, C, proteins, carbohydrates, Zinc, Iron, Sugars, those type of things. Digestion involves your digestive system a.k.a small intestine, large intestine, stomach. Digestion breaks down food in order to get nutrition

Here's one.  http://arbl.cvmbs.colostate.edu/hbooks/pathphys/digestion/stomach/rennin.html\n\nTurn your volume down before going there.\n\nI am only giving a part answer so you will learn better how to use internet search...

im studying the digestive system right now, so i'll have a go at this question (u may want to chec accuracy).\nthe cell gets the carbon it needs via the blood supply. when we eat, all the nutrients are broken down and molecules such as hydrogen, oxygen and carbon are filtered into the blood stream so that they can be passed on to all the cells in th body.\n\ndoes that help?

It's sort of both. Digestion begins when you put food in your mouth. The act of chewing mixes saliva with the food, which starts breaking the food down. Putting food in your mouth is voluntary, because you control it. Once you swallow the food, it becomes involuntary. \n\nThe cerebrospinal system, made up of the brain and spinal cord and their attached nerves, controls all voluntary functions, and some usually involuntary, like breathing. \n\nThe autonomic system, consisting chiefly of a connected series of ganglia lying alongside the vertebral column, controls such vital processes as circulation, digestion, swallowing, respiration, and is subject to influence from the emotions, but not from the will. \n\nThe answer you probably wanted was that it is involuntary.

I agree with the above answer--- proteins.\neverything that we eat is made up of the basic amino acids or protein that is how we are able to digest them or consume them.

As Beare85 said, the matter comes in as nutrients or food. Metabolism consists a series of reactions that happens in the body and in cells, taking in food (potato, beef and so on), brakes them down into the smallest biological molecules (particles such as proteins, carbohydrates, fat, and other minerals and vita mines, while storing the energy of those bonds), then uses them as building blocks for their functions. In the body, a lot of the breaking down happens in the digestive system, and is spread through the body in the blood. Cells absorb nitriente mostly as building blocks already. Cells are mostly proteins, lipids (fat) and water. It all comes from food.

Dietitians relate to biology by understanding how food (healthy and otherwise) interacts with the human body, and how it effects our health and system.

No.Certainly not.If your digestive system is working properly,your daily food will give you what you need. If it is not fuctioning well no supplement will work permanently.\nSo it is best to improve digestion.stick to wholesome diet.

Peristalsis is a method or a occurence that happens when the food goes down the digestive tract. the frequent  relaxation and contraction of the muscles in the digestive tract allow the food to go from the mouth to your stomach\n\nChyme is the food that is partially digested and it is transferred from stomach to the duodenum (the entrance of small intestine)\n\nVilli is something hair-like structure that is present in your small intestine. The major function of villi is to absorb nutrients\n\nIt ususally takes an two and half to six hours for food to be done in the digestive system.\n\nThe function of the large intestine is to absorb water, vitamin and electrolytes\n\nYou mean the digestive tract? about 9 meters.. or 30 feet

In humans, digestion begins in the mouth where food is chewed with the teeth. The process stimulates exocrine glands in the mouth to release digestive enzymes such as salivary amylase, which aid in the breakdown of food, particularly carbohydrates. Chewing also causes the release of saliva, which helps condense food into a bolus that can be easily passed through the esophagus. The esophagus is about 20 centimeters long. The food is pushed down by a movement called peristalsis, which is the wave-like contraction of smooth muscle tissue characteristic of the digestive system.\nThe food enters the stomach upon passage through the cardiac sphincter. In the stomach, food is churned and thoroughly mixed with a digestive fluid, composed chiefly of hydrochloric acid, and other digestive enzymes to further decompose it chemically for a few hours. As the acidic level changes in the stomach and later parts of the digestive tract, more enzymes are activated or deactivated to extract and process various nutrients.\nAfter being processed in the stomach, food is passed to the small intestine via peristalsis. It passes through the pyloric sphincter and enters the first 10 inches of the small intestine, the duodenum, where it is further mixed with 3 different liquids, which are bile (which helps aid in fat digestion), pancreatic juice (made by the pancreas), and intestinal juice. They also add several enzymes: maltase, lactase and sucrase, to process sugars. (Bile also contains pigments that are by-products of red blood cell destruction in the liver; these bile pigments are eliminated from the body with the feces.) Most nutrient absorption takes place in the small intestine. The nutrients pass through the small intestine's wall, containing small, finger-like structures called villi. The blood, which has absorbed nutrients, is carried away from the small intestine via the hepatic portal vein and goes to the liver for filtering, removal of toxins, and nutrient processing.\nAfter going through the small intestine, the food then goes to the large intestine. The large intestine has 3 parts: the cecum (or pouch that forms the T-junction with the small intestine), the colon, and the rectum. In the large intestine, water is reabsorbed, and the foods that cannot go thorugh the villi such as fiber, can be stored in large intestine. Fiber helps to keep the food moving through the G.I. tract. The food that cannot be broken down is called feces. Feces is stored in the rectum until it is expelled through the anus.\n\n\nIt's long I know, but it's fairly simple words.

Greens and Protein. Vegatables are loaded with fiber, vitamins, and fill you up. However they break down slowly, and a lot of the energy they give off and used right back up to digest them. for instances, you may consume something with 400 calories, but your body actually requires 100 calories to digest it, total calories obtained is 300. Sugars and processed foods are very easy for your body to break down, and offer tons of energy. If you don't use that energy, it becomes fat.

A medicine is something that is given in minute quantities, usually to treat/heal a particular disease condition. As such, it does not provide nourishment to the body.\n\nFoodstuff is something taken in bulk quantities to nourish the body. It provides one or more of the following: carbohydrates, proteins, minerals, vitamins, fats.\n\nMedicines need testing because they usually contain alien chemicals, the effects of which are unknown on the body. \n\nThere has been in recent times an emergence of class called neutraceuticals. These are mainly high-end nutritional supplements; taking these over a period of time helps in healing the body.

Your body gets energy by metabolising carbohydrates (starches and sugars) and fats (lipids).\nProteins are used for the growth and repair of body tissues.\nVitamins and minerals are essential for the chemical process that make our body work.\nFibre (roughage) - which is all the undigestible parts of our food, mostly cellulose - is needed to allow our gut to  efficiently move stuff through it.\nCreatine is a dietary supplement and is not necessary if you have a normal, healthy balanced diet.\nAthletes improve their stamina by training regularly.\nFor reliable medical/scientific advice on nutrition look here:

MOUTH -  The teeth break food into smaller bits, which are  formed into a soft ball, called a bolus, by the tongue. Saliva lubricates the food and begins chemical digestion.\n \nPHARYNX -, or throat The pharynx pushes the bolus into the   esophagus.\n  \nOESOPHAGUS - The bolus is moved through the 10-inch esophagus by a series of coordinated, wave-like contractions. At the end of the short journey, the opening to the stomach relaxes and opens until the bolus of food passes, then closes again to prevent stomach contents from backing up. \n \n STOMACH - The stomach muscles pummel food and churn it with gastric juices containing enzymes and hydrochloric acid, killing potentially harmful bacteria and microorganisms and continuing the breakdown of food into smaller and smaller pieces. The resulting material is now called chyme. Four hours (longer if a meal includes fatty foods)\n \nSMALL INTESTINE -The duodenum (the first section of the small intestine) adds bile and pancreatic juice to the chyme, which helps the intestines digest and absorb nutrients from the food. Most digestion and absorption take place in the small intestine. Food first spends four hours in the duodenum, then two hours in the rest of the small intestine \n\nLARGE INTESTINE - Sodium and other salts, and most importantly water, are absorbed here. Leftover waste material is slowly pushed through the colon by muscular contractions until it reaches the rectum. Stool is ultimately eliminated from the body during a bowel movement from the rectum.  \n\n\nHOW LONG BOLUS IS DERE ( TIME)\n\nMOUTH- MINUTES OR LESS\n\nPHARYNX- SECONDS\n\nOESOPHAGUS- One to six seconds for liquids  \n            30 to 60 seconds for solids\n\nSTOMACH- Four hours (longer if a meal includes fatty foods)\n\nSMALL INTESTINE-Food first spends four hours in the  \nduodenum, then two hours in the rest of the small intestine\n\nLARGE INTESTINE-14 HRS
