The goat is considered a ruminant animal. The digestive system includes the mouth‚ esophagus‚ four stomach parts‚ a cecum‚ a small intestine and a large intestine. Goats have no upper teeth so they use the dental pad‚ lower teeth‚ tongue and lips to eat their food. The four compartments to the stomach are the rumen‚ the reticulum‚ the omasum‚ and the abomasums. The esophagus is what moves food from the mouth to the stomach. It opens into the stomach at the opening of the rumen and reticulum‚ which

carried out by enzymes. Mechanical digestion: Is the physical breaking down of larger food into pieces to increase its surface area (the higher the surface area‚ the higher the rate of chemical digestion. Peristalsis: the squeezing of the digestive tract that pushes food down in one direction. Bolus: the partially digested food that is swallowed after mastication. Chyme: the partially digested food mixed with the enzymes and acid in the stomach. Bile: The secretion produced by the

Human Digestive System Single-celled organisms can directly take in nutrients from their outside environment. Multi-cellular animals‚ with most of their cells removed from contact directly with the outside environment‚ have developed specialized 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

University of Phoenix Material Animation: The Digestive System Hydrolysis of Sucrose After viewing the animation‚ answer these questions: 1. The enzyme sucrase breaks the disaccharide Sucrose into two monosaccharides: Glucose ‚ or sugar‚ and fructose ‚ or fruclose sugar. 2. Where does this reaction occur? This reaction occurs on the surface of the instetina epithelial (mucosal) cell surfaces. 3. For hydrolysis to occur‚ the sucrose must bind to what part of the

Structure and Function of the Human Digestive System By Caitlin Ong Organs of the Digestive System Mouth Structure: The mouth consists of the upper and lower jaw‚ that contain gums which hold teeth‚ the roof of the mouth is the palate and the tongue occupies the floor of the 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

RT Year 8 Science Body System Investigation My Question: Do plants have or need a digestive system? Some plants have digestive systems‚ but those plants live in marsh areas because they can’t get adequate nitrogen. But most plants don’t have digestive systems. Plants that don’t have digestive live in soils and environments that contain all the nutrients and other things they need. Plants that have a special type of digestive system that is much different to humans live in areas with not enough

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
