C. Calculus Formation Relationship with Plaque: * Calculus is formed by the deposition of calcium and phosphate salts in bacterial plaque. These salts are present in salivary and crevicular fluids. * Plaque mineralization begins within 24-72 hours and takes an average of 12 days to mature. * Calculus contributes to the disease by providing foci for plaque accumulation. It is not the causative or etiologic factor‚ plaque is. * Calculus is porous and can act as a reservoir or nidus

DIGESTIVE ENZYMES AND THEIR FUNCTIONS Mouth -the oral cavity or the mouth contains salivary glands that secrete a wide range of enzymes to aid the first step of metabolism of food. The salivary gland secretes the enzyme lysozyme which has an antibacterial action. The enzymes secreted by the mouth mainly provide protection against bacteria. Betaine helps to maintain a fluid balance inside the mouth. The lists of digestive enzymes secreted by the oral cavity are mentioned in the table. Enzymes

Observation of Digestive and Circulatory System Introduction/Background: This week’s lab is about digestion and the circulatory system. Students will be learning about the different types of digestion and circulatory systems for different types of animals. Students will learn not only about the mechanical and chemical components of digestion‚ but also the complete and incomplete digestions. The lab will also teach the open and closed‚ single and double‚ circulation patterns. Several different models

Your Inner Fish Your Inner Fish by Neil Shubin‚ delves into the questions of why the human body looks the way it does. Looking at the earliest forms of vertebrate life on land and even to the earliest forms of life on Earth we can trace the evolution of the human body. The creatures‚ from millions of years ago‚ have left us with a genetic a imprint that reveals how similar we truly are to the other creatures on Earth. Shubin tells the story of evolution by tracing the skeletal features and organs
