Physiology The mechanical and chemical digestion of carbohydrates starts in the mouth. Chewing also termed as mastication ensures that the carbohydrates crumble down into smaller pieces. There are salivary glands within the oral cavity that secrete Continue Reading...
Chemical reactions occur when atoms, molecules, and ions interact with one other to form new substances. Chemical bonds are broken and new bonds are formed. Chemical bonds between atoms follow rules based on patterns of electron distribution within t Continue Reading...
The blood and lymph systems are also vital to digestion's efficacy, transporting nutrients to the cells of the body where they are needed (Smith & Morton 2001). Again, most of the "action" of the accessory organs and their products takes place i Continue Reading...
Chemical Digestion When the body can not break down food by the physical means it has, the body must therefore use chemical digestion to help finish the job. Chewing food with teeth is an example of physical digestion, but that is just the beginning Continue Reading...
Nutrition-Health-Science The Digestive System Mechanical digestion begins the process of digestion. Otherwise known as chewing, it "involves mixing, grinding, or crushing large pieces of food into small pieces" (Lab: Mechanical and chemical digesti Continue Reading...
Lipids and Proteins Lipids Lipids are fats and they are important to our health. When chemically digesting these lipids or fats, these molecules are broken down into smaller ones that can be more readily passed through the digestive system and into Continue Reading...

This chemical process happens all along the digestion track. Yet, eating the carrot provides a different digestion response than eating a greasy piece of pizza. When one digests a carrot, a plant food source, one is consuming mainly starch-based nu Continue Reading...
Proteins are often called the building blocks of life. In fact, the very word "protein" implies their importance in the body: it is a Greek word meaning "first place." Approximately fifty percent of the dry weight in animal cells is comprised of prot Continue Reading...
living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant Continue Reading...

Experimental Design for Hypothetical Research Study Recent research has emerged which suggests that the ingestion of chocolate may lead to improved cognitive function within the realm of memorization and retention of information. Establishing a conc Continue Reading...
Chronic Liver Disease With a number of functions -- including detoxification, protein synthesis, and the production of chemicals that are necessary for digestion -- the human liver is vital. It is reddish brown and has four unequal sized lobes; usu Continue Reading...
The amount of carbohydrates, rather than the source, is the primary concern. Blood glucose levels are influenced by the food preparation process, the amount of food, sugar absorption and the combination of foods. Carbohydrate counting assigns certa Continue Reading...

When DNA is damaged, cells can react through cell cycle checkpoints which allows repair to begin before further division can occur. There is also the prokaryotic SOS response which changes gene expression in bacteria as a result of DNA damage. This Continue Reading...
There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the func Continue Reading...
Phylum Annelida Annelids are members of the Superphylum Lophotrochozoa. The division of the Phylum is in three classes Hirudineans (leeches), Oligochaetes (earthworms) and Hirudinean (Polychaetes and leeches). They inhibit marine aquatic with Parapo Continue Reading...
There are, of course, other methods that have been developed for the reduction of destruction to agricultural crops from pest insects such as the Manduca sexta, including the use of aqueous vermicompost solutions as fertilizers for plant growth (Ed Continue Reading...
However, treatments can be used to reduce, if not nearly completely diminish, symptoms and minimize any other complications. Here are the conditional means: Therapy: People with cystic fibrosis need a way to physically remove thick mucus from thei Continue Reading...
healthy Nutrition: A Chemistry View Point Chemistry is a branch of sciences that deals with the compositions of matter and helps in identifying the substances that form matter. Living as well as non-living bodies are formed with substances. These s Continue Reading...
It is also at this point that other organs begin to play a major role in the digestive process. The pancreas, located adjacent to the small intestine, secretes several enzymes that variously break down carbohydrates much further than they were broke Continue Reading...
Cellulase helps to digest cellulose, which is the main component of fibrous diets. In patients with yeast overgrowth (Candida symptoms) the use of cellulase enzyme can be very effective. Yeast cell membrane contains a chemical known as chitin, which Continue Reading...
