Chemical and Physical Process of Digestion Essay

the small intestine and the stomach. It produces chemicals needed as materials move between the two. The pancreas quickly lowers the acidity in the small intestine and breaks down proteins, fats, and starch. The chemicals produced by the pancreas are extremely important for digesting and absorbing food substances. Without those chemicals you would die of starvation even with plenty of food in your system, because your body would not be able to process and use your food for energy. -Liver- Largest internal

separated into groups called Autotrophs and Heterotrophs according to how they consume and make their energy. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy. Heterotrophs cannot synthesize their own food and rely on

turn into fuel for the human body? Using the digestive system and its many organs through the process of digestion and metabolism is how our bodies receive the energy it needs to continue. Chemistry can be seen as food starts its process from entering to leaving the body, through the rate of our

Physiology and anatomy are the two main terms in accordance with study of the human body or living matter. Physiology is defined as the study of how living organisms function, including processes such as movement, nutrition and reproduction. Anatomy is study of the structure of a living organism and all the components; including cells, tissue and organs. (St. Patrick’s, 2017). In response to task 1 I have created a table illustrating each of the 10 body systems and their main anatomical features

Digestion Lab Notebook Due Sunday at Midnight CST Week 6, Worth 100 points, pg. 105 Questions: 60 points Data/Results: 15 points Summarizing activities: 25 points Name: SC 245 Lab Date: Exercise 8 Chemical and Physical Processes of Digestion, pg. 105 Introduction: In this lab, I will learn how the complex digestive system breaks down substrates such as fats, proteins and carbohydrates. Activity 1: Assessing Starch Digestion by Salivary Amylase Data: Chart 1 – Salivary Amylase

digestive system has six main functions: ingestion, secretion, mixing and movement, digestion, absorption, and excretion of food (Tortora & Derrickson, 2009). Alimentary canal Organ Structure Function Diagram Mouth The mouth is made up of the checks hard and soft palates, internally and externally covered with skin. The mouth is where food enters the body and the process of digestion starts via mechanical and chemical digestion. oesophagus The oesophagus is a long tube

In 1972 the Clean Water Act (CWA) was passed, and it established the infrastructure for waste-water management in the U.S. The CWA’s main objective is to ‘recover and preserve the physical, biological, and chemical purity of water. The CWA formed a program that would ensure communities had clean water by limiting the exposure of contaminants in U.S. waterways. Waste-water treatment is essential to the world because it gives people ability to use streams and rivers for swimming, fishing and drinking

down into smaller pieces through chewing, which is a form of physical digestion. The tongue moves it around in our mouth, and the salivary glands produce saliva which mixes with the apple to begin the breaking-down process, which is called chemical digestion. The enzyme in the saliva, called amylase, begins breaking down starch from the apple into sugars such as glucose. There also other enzymes in our mouth that begin the digestion process and these include lipase, which digests the very small amount

acids. When food is broken down energy is released as the foods molecules’ bonds are broken. Then this energy is used to reform the bonds that have been broken so that ATP can be recreated. More energy can be obtained when oxygen is present and the process proceeds on aerobically. The aerobic production of ATP occurs inside the mitochondria in cells. The broken down food molecules then enters the blood stream. Blood is a liquid connective tissue as it is made up of red and white living cells. Oxygen

been treated with pesticides, ionizing radiation, antibiotics and or any foreign substance that can change the way the organism functions. GMO stands for Genetically Modified Organisms and they are the opposite of organic. GMO foods contain many chemicals that can cause some serious and some minor damage to anything. Organic food is better for people to consume than GMO food because of the negative effects GMO’s have on individuals such as; the way people grow, the abundance of GMO side effects
