Human Digestion Shaunda SCI/241 05/16/14 Human Digestion From what I have learned from the weekly readings and watching the animated digestive tract. When humans digest food‚ we go through a complex process‚ in which the food eaten is turned into energy that is needed in order to survive. During the digestion process the food eaten becomes waste that has to be eliminated eventually. I will discuss how this process works in each area of mouth‚ stomach‚ small intestine

Thermohaline Ocean Circulation #1- What is The Thermohaline Ocean Circulation concept? The Thermohaline Ocean Circulation is when the circulation of the ocean is caused by heat and freshwater in the sea’s surface. This causes the mixing of heat and salt in the ocean. Thermo is temperature and haline is salt. Temperature and salt are the two factors that determine the sea’s density. The circulation causes differences in seawater density. The circulation also causes warm water from the southern hemisphere

EXPERIMENT NO. 12 DIGESTION IN THE STOMACH ABSTRACT____________________________________________________________________________ Digestion refers to the mechanical and chemical breakdown of food into smaller components that can undergo absorption. The objective of this experiment is to investigate mainly the process of digestion in the stomach. The conditions at which the enzymes responsible for the digestion process were determined. Also‚ the total and free acidity of gastric juice of the sample

Energy in context Introduction Digestion is the breakdown of large insoluble food molecules into smaller molecules so they can pass though the intestinal wall into the bloodstream and be transported throughout the body. There are seven different food groups in a balanced diet which should include Carbohydrate‚ fat‚ water‚ protein‚ fibre‚ vitamins and minerals.

It helps the body grow‚ provide protection from sickness and disease‚ function properly‚ and even live. There are many types and forms of nutrients that each do specific or multiple jobs. They are classified in six main groups. Carbohydrates‚ proteins‚ fats‚ vitamins‚ minerals and water are all the different groups. Proteins are nutrients that help build and

Digestion a. The mouth: salivary alpha enzyme chew food‚ perceive taste‚ moisten food with saliva‚ lubricate food with mucus‚ release starch –digesting (amylase) enzymes‚ initiate swallowing reflex - Enzyme: alpha amylase with cooked starch as substrate – starch digestion enzyme an enzyme that catalyses the breakdown of starch into sugar - The Functions of Saliva - 1. Moistens and lubricates food‚ permitting swallowing 2. Holds taste producing substances in solution and bring them in

The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands. Saliva moistens the food and carries dissolved food molecules to the taste buds. Saliva helps digest food because it contains enzymes that start to break it down. After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that
