Peristalsis is: a) the rhythmic contraction of the smooth muscle in the gut wall to push food along b) the secretion of bile into the small intestine when a fatty meal is eaten c) the churning movement of the stomach to mix its contents d) the rhythmic contractions of the diaphragm to produce hiccups 2. Arrange the following parts of the digestive system in the order in which food passes through on the

Where food enters the body. Chewing and salivary enzymes in the mouth are the beginning of the digestive process (breaking down the food). Teeth: Used to break food down by (chewing) into smaller particles. Tongue: is used to manoeuvre food that is being chewed. Pharynx: tube-like structure that connects oral and nasal cavities to the larynx; provides passageway for respiratory and digestive tracts. Located in the back of the oral cavity. Esophageal opening: The entrance to

First the Homo sapien will be insert the food into its alimentary canal. It will then chew the food creating a bolus of food‚ which is caused by the enzymes in the saliva which break down the food making it ready for swallowing or deglutition. The bolus of food goes through the larynx‚ which is the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals. The bolus of food passes through the oesophagus. The oesophagus is a muscular tube which

days ANALYSIS: The Digestive System- THE MOUTH: 1. Teeth: Pigs teeth have to be sharp and pointed so they can chew their food well so it can be transferred to the stomach. Hard Palate: The hard palate has to be hard and rippled so they food can be broke down easier‚ while it’s being chewed it will hit the hard palate and break down easier. Tongue: It’s supplied with a number of muscular valves. That control and direct the amounts of food through the Digestive tract. Epiglottis: The Epiglottis

organisms. Throughout the digestion process‚ food is broken down into small molecules‚ where it can be absorbed easily. There are many organs that aid in this complex task. Ingestion‚ digestion‚ and absorption are the three necessary steps of the digestive process. First‚ food is ingested. Ingestion takes place in the mouth. Once food enters the mouth‚ teeth chew it. The salivary glands produce saliva‚ which is mixed with food while chewing. Saliva helps break the food into smaller pieces. These

Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

membrane. The alimentary canal walls have four basic layers or tunics. These are the mucosa‚ the submucosa‚ the muscularis externa‚ and either a serosa or adventitia. Each of these layers has a predominant tissue type and a specific function in the digestive process. The mucosa is the wet epithelial membrane abutting the alimentary canal lumen. The major functions of the mucosa are secretion‚ absorption of digested foodstuffs‚ and protection. The submucosa’s major function is nutrition and protection
