Big Idea: Organ systems have complex interrelationships to maintain homeostasis
Analyze cause-and-effect relationships Construct, analyze, and interpret graphs, models, and/or diagrams Consider the changes in knowledge over time as tools and technologies have developed
By the end of this lesson, students are expected to demonstrate understanding of the following: Digestive system: Structure and function Structural and functional interdependence Maintenance of homeostasis
Topic: Organ systems have complex interrelationships to maintain homeostasis. Homeostasis is maintained through physiological processes.
Goals Objectives Materials Introduction Development
Students will be able to: Describe the function of the digestive system and its major organs. Describe the relationships between the different components of the digestive system. Explain how the digestive system is interdependent with the circulatory system. Explain how the digestive system maintains homeostasis in the body. After this lesson stude...
Include a First Nations land acknowledgement and ask students to reflect on what respect for animals means to them. Provide an introduction to the apps and models that will be used in class. Provide an overview of how to access 3D Anatomica workbooks if teaching remotely.
In biology, homeostasis refers to the body’s ability to maintain a stable internal environment despite changes in external conditions.
The digestive system is responsible for taking whole foods and turning them into nutrients and energy, which allows the body to function, grow and repair itself. Mouth, esophagus, stomach, small intestine, large intestine, rectum, liver, pancreas, gallbladder. Homeostasis, mouth, salivary glands, salivary amylase, palate, esophagus, pharynx, epiglo...

Chemical Digestion: saliva breaks down carbohydrates/starches 3 sets of salivary glands produce saliva to lubricate and break down the food. Teeth: mix of canines and molars to masticate (tear/bite/grind/crush) the food into smaller pieces. Tongue: muscular organ that mixes the food with saliva and aids with swallowing. Salivary Amylase: enzymes th...
Feces are formed from indigestible food, excreted materials and bacterial cells. Feces leave through the anus. Anus normally held closed by internal (smooth) and external (skeletal) anal sphincters. Functions:
A mucus layer prevents the HCl from eating through Pepsin could digest the stomach pepsin is until it mixes Mucus cells: secrete protective coat Parietal cells: secrete HCl (pH 3) which kill bacteria and help breakdown food Peptic cells: secrete pepsinogen, which forms the enzyme pepsin when combined with HCl. Pepsin is a hydrolytic enzyme that bre...

Produces glucagon: stimulates conversion of glycogen into glucose (glucagon secreted when high glucose levels detected in blood) This regulates blood sugar. glucose level food, insulin is secreted which causes ...

Ask students how they think the different organ systems work together based on what they've learned so far – specific questions can include: How does the integumentary and digestive system interact? How does the muscular system aid in digestion? Does the digestive system produce any hormones ? How do they interact with the body? What does the Hepat...
The skin provides vitamin D, which plays an integral role in the absorption of vitamin C in the digestive tract, and helps protect the digestive tract. The digestive system provides nutrients required by skin, hair, and nails.
Peristalsis is created by smooth muscles, while skeletal muscles aid in voluntary sphincter control, swallowing, and protect and support abdominal organs. The digestive system provides cellular energy (ATP), which is required by muscular cells, from micro-nutrients produced in the digestive tract. Lactic acid build up after muscle activity is metab...
Endocrine hormones aid in secretion regulation in accessory organs and digestive glands; glucose storage in the liver is controlled by insulin and glucagon. Hormones are also produced by the small intestine and stomach.
Blood vessels transport nutrients from the digestive system to various other parts of the body. Nutrients from the digestive system are provided for the formation of blood cells and plasma protein. Plasma proteins are produced by the liver. It also destroys old red blood cells and detoxifies blood.

Inferior Capillary Hepatic Large Capillary bed Small The hepatic portal system is a series of veins that carry blood from the capillaries of the stomach, intestine, spleen, and pancreas to capillaries in the liver. It is part of the body’s filtration system. Its main function is to deliver de-oxygenated blood to the liver to be detoxified further b...
To keep the internal environment in the body functioning properly, maintaining homeostasis is required. The digestive system, along with other body systems, help maintain energy homeostasis.
The formative assessment can be in the form of an exit slip. This involves asking each student at the end of the class to answer 2-3 questions on a sheet of paper and hand it in, with their names on it, to ensure understanding of the main concepts covered.

The digestive system is the group of organs responsible for the digestion of food. They assist in the breakdown of food in order to extract the nutrients the body requires to grow, repair itself, and maintain health.
