Neale SBI3U1 November 6th‚ 2014 Spit and Armpit Lab Partners: Kara Washer and Josh Young Abstract This lab shows the use of salivary amylase with strong and weak starch mixtures to break down complex carbohydrates into simpler sugars. This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It is found that benedict’s

Human Digestion SCI/241 Human Digestion The beginning of the digestive process starts with the smell and sight of food which activate the salivary glands. The mouth is the point at which food enters the digestive tract and continues the digestive process by chewing food. The food is then broken down into pieces and moistened by salivary glands which turn food into a bolus. The bolus goes down the pharynx into the esophagus which connects the pharynx to the stomach. The stomach is an organ

Measles(rubeloa) and Rubella are not the same‚ but they do share similar caracteristics. Rubella is caused by a different virus is not as severe or infectious as measles. Symptoms include low-grade fever‚ nausea‚ swollen glands‚ mild- conjuctavitus. In adult‚ arthrits or joint pain can occur. If a woman is sick and contracts the virus early in her pregnancy‚ there is a ninety percent chance that she will pass the virus on to her baby. Contracting this virus while pregnant

Salivary gland cancer occurs in the glands that produce saliva‚ located in front of and just below each ear (parotid glands)‚ under the tongue in the floor of the mouth (sublingual glands) and below the jawbone (submandibular glands).

structures for obtaining and breaking down their food. The human digestive system is a complex series of organs and glands that processes food. It is a coiled‚ muscular tube (6-9 meters long when fully extended) extending from the mouth to the anus. Inside this tube is a lining called the mucosa. In the mouth‚ stomach‚ and small intestine‚ the mucosa contains tiny glands that produce juices to help digest food. This tube also includes the pharynx‚ esophagus‚ large intestine‚ and anus.

mouth. The salivary glands have ducts that open in the mouth. Function: The mouth is where the first step of digestion begins. Known as mechanical digestion‚ this involves chewing with your teeth to break the food into smaller pieces. The tongue moves the food around to assist chewing and together with saliva‚ the food is lubricated for ease of swallowing. Salivary glands Structure: There are three main parts of salivary glands: the parotid‚ the submandibular and the sublingual glands. Function:

water keeps up your liquid levels. What Happens in Each Organ During the Process of the Digestive System? The Mouth: This is where the digestion of food starts‚ even before you take a bite of a Cheese Sandwich‚ the smell of it triggers the salivary glands in your mouth to create saliva‚ making your mouth water; when the food is in your mouth‚ the saliva increases. The food is broken down into small pieces by chewing‚ which are then small enough to be digested. More saliva is produced to begin the

The beginning and end of a cheeseburger Scott Johnson The process all begins when one begins to bite into a cheeseburger. The lips and cheeks are very important in this process of mastication‚ or chewing. They help manipulate the hamburger and its add-ons within the mouth and hold it in place while the teeth crush or tear it. The incisors and canines primarily cut and tear the hamburger‚ while the premolars and molars primarily crush and grind it. Mastication begins the process of mechanical

How would the answers to the above question change if the question had asked about centromeres and chromatids rather than chromosomes and DNA molecules? 4.
