Class started with 10 question weekly quiz.
Using a diagram of the large intestine, the anatomy was outlined, including the ascending, transverse, and descending colon along with the appendix.
The physiology of the colon, absorption of water, vitamins and minerals outlined as the main function.
The physiology of defecation explained, along with the voluntary control of the anal sphincter muscle and the stretch spinal cord reflex which initiates the process.
Some disorders of the colon are discussed, along with treatments

Absent.

During today's class, we continued learning about the anatomy and physiology of the urinary system. Lena took her notes and then we watched a short video.

Complete discussion of chemical digestion within the stomach.
Explain what an emulsion is, and an emulsifying agent.
Relate that bile is an emulsifying agent, produced within the liver and stored in the gall bladder. It is released upon hormone stimulus.
Discuss the completed digestion of chyme in the small intestines, the glands involved, the enzymes produced, and the end products of the digestion.
Absorption of digested nutrients is facilitated through the action of villi and micro villi.
Show the structure of the villi using a diagram, and stress the importance of the capillaries and the lacteal.
Introduce how gall stones will block the common bile duct and some methods used to treat.

Continue with the alimentary canal, from the pharynx to the stomach to the small intestine.
Discuss peristalsis and the pyloric sphincter valve which closes off the stomach.
Examine the structure of the stomach's muscular wall, with muscles running circular, longitudinal and oblique. This aids in mechanical digestion.
Outline the chemical makeup of gastric fluid, and which type of cells in the stomach lining produce the enzyme, the acid, and the mucus.
Define chyme and indicate that the chyme will move into the small intestines when it reaches a certain consistency. Briefly indicate the importance of the duodenum in the system

Lab whose aim is to demonstrate how salivary amylase works as an enzyme in saliva, and what complex nutrient is hydrolyzed through its action.

Absent

Quick review of the organs of the alimentary canal and the accessory organs.
Separation of digestion into mechanical and chemical digestion.
Outline the organs of mechanical digestion, and the need for mechanical digestion.
Discuss enzymes as catalysts and their role in hydrolysis of nutrients.
List the major nutrients and discuss the chemical makeup of each one.
Begin with carbohydrates, their chemistry, how they are polymers, and the monomers which compose them.
Show hydrolysis from polysaccharide to monosaccharide, and the need for this organic simplification.
Introduce salivary amylase as the enzyme found in saliva and its main function in digesting polysaccharides into di and tri saccharides.

Review/view video: Once upon a time-"Life"( the brain)
Practice and demonstrate brain exercises.

Administration of the Pearson practice test.
Introduction into the digestive system.
Purpose and definition.
Introduction to the alimentary canal
