The break down activities that

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

6 primary functions of digestive system: 1. Ingestion- food intake 2. Secretion 3. Digestion- mechanical & chemical breakdown of food Mechanical Mastication- first step. Enables mixing with saliva to form bolus to be swallowed. Regulated by CNS. Deglutition Mixing/Churning Peristalsis- movement of muscles within GI tract that facilitates movement of food Chemical- Hydrolysis (using H2O) of macromolecules into monomers (residues) carried out by digestive enzymes produced by salivary glands

Parts of the digestive system The digestive system consists primarily of the alimentary canal‚ a tube that extends from the mouth to the rectum. As food moves through this canal‚ it is ground and mixed with various digestive juices. Most of these juices contain digestive enzymes‚ chemicals that speed up reactions involved in the breakdown of food. The stomach and the small intestines‚ which are parts of the alimentary canal‚ each produce a digestive juice. Other digestive juices empty into the alimentary
