INT1 Task 3 Do more expensive paper towels absorb more water than less expensive products? By: Gregory M. Herrin Project design Plan When consumers are in the store to purchase paper towels, there are numerous options and brands to choose from; all claiming to be the best product with the most absorbency. How does a consumer choose the best option for the best price? The goal of this experiment will be to determine if higher priced paper towels are more absorbent than the less expensive paper

The mouth is the first-place digestion occurs. In order that the surface area is increased, the teeth crush and grind the food into smaller pieces. As the tongue presses the food against the hard palate of the mouth, saliva mixes in and the food is now described as a bolus. Saliva, produced by the salivary glands, contains mucus combine the bolus and lubricate it, lysozymes to kill any bacteria, and amylase that breaks down starch. However, only a minute amount of starch is actually broken down.

beta-glucans) which are resistant to digestion in the small intestine and require bacterial fermentation located in the large intestine. These enables smooth bowel movement, prevent constipation, hemorrhoids, cardiovascular diseases (CVD), type 2 diabetes and diverticular disease. Dietary fibres contain combination of resistant starches, vitamins, minerals, phytochemicals and antioxidants. Since indigestible, it consists of components of cell wall which are resistant to digestion by human digestive enzymes

Body fluid compartment and water balance The human body fluids are divided two major fluid compartments. Fluid compartments are mainly used to compare the situation. It is the intracellular and extracellular fluid. These two fluid compartments are account for total body water. The two main parts of the body fluids are watered and make up the body's tissues. Fluid compartments are a location relative to the membrane of the cells. The intracellular fluid system includes all fluids in cells plasma membrane

PHYSIOLOGY QUESTIONS Diffusion refers to the process whereby molecules move from a high concentration to a low concentration across a semi-permeable membrane. DIFFUSION REFERS TO THE PROCESS WHEREBY SOLUTES MOVE FROM A HIGH CONCENTRATION TO A LOW CONCENTRATION ACROSS A SEMI-PERMEABLE MEMBRANE UNTIL EQUILIBRIUM IS REACHED. Osmosis is the diffusion of water from an area of low osmolarity to an area high osmolarity across a selectively permeable membrane. OSMOSIS REFERS TO THE DIFUSION OF WATER

Signals for starting a meal | Signals for stopping food intake – Meal size | Signals for controlling food intake – Body weight | Pinel (2007)In Western countries, people usually eat to a set schedule, and the digestive system starts to prepare itself by releasing saliva and enzyme just before meal time. This represents a learned response, anticipating the presence of food. | Role of Cholecystokinin CCKThe hormone CCK has an opposite effect to ghrelin. Studies have shown that injection of the CCK

Williams January 7, 2015 SCI/241 Shirlene Small Digestion is movement of breaking down what food you consume in your body through your mouth into molecules so that the body can absorb it. “Proteins, carbohydrates, and fats in our diets must be broken down and later, reassembled in forms useful to our body.” (Carter, 2014) We often eat foods that are hard to digest or we have a problem that won’t allow us to digest foods properly. The digestion process is very important for our bodies to provide

I never knew a little girl could be so brutal. She unwrapped me and took the biggest bite known to man (Ingestion). As I was ingested she kept me in her mouth for thirty seconds before she started breaking me down with her teeth (Mechanical digestion). I was now on her tongue. Her salivary glands begin to produce saliva that moistens me up and break down the carbohydrates I have stored in me, and this enzyme is called salivary amylase. (Propulsion) As she continues to mix me with her saliva
