Unit 5 Reflection

Fed State Poster

In this unit we learned about the digestive system, metabolism, diabetes, endocrine system and the lymphatic system.  We learned that there are six basic functions of digestion, ingestion, secretion, mixing/propulsion, digesting, absorption, defecation. The digestive system has many accessory organs and we found out the pathway that food takes. ATP is the universal carrier for metabolism and it can be generated by the oxidation of glucose, fatty acids and amino acids. It takes three stages for energy to be extracted from food. We learned more about diabetes and what causes it.  Diabetes is when your body cant properly control blood glucose levels and you body cant make enough insulin, and it cant respond to it. Type 1 diabetes is when the body doesn't produce insulin at all and they must take insulin by injecting it. Type 2 diabetes begins with insulin resistance and is more common then type 1 diabetes.  The endocrine system controls the processes involved in movement and physiological equilibrium.  We learned about the organs in the endocrine system and their hormones. We were taught about the lymphatic system and how it is involved in immunity, lipid absorption and fluid recovery.  Lymph is a clear colorless fluid that flows throughout lymphatic vessels.  The main organs of the lymphatic system are Lymph nodes, thymus, tonsils and spleen. In this unit we did a lab where we measured out our digestive tracts with strings, and we found out that it is a lot longer then we thought it was.
