Warm Up (Silent) 9/14 Track a protein through a cell, from where the information is stored to make the protein to where the protein leaves a cell. Include each organelle and the function of the organelle. (Hint: One organelle is used twice)

Reminders: Cell Analogy due in one week! Reading Quiz Tomorrow 9/15, pages

Homeostasis A condition in which the internal environment of the body remains relatively constant despite changes in the external environment. What conditions does your body have to keep in equilibrium?(temperature … what else?)

Cupples Activity Read the short intro and then fill out the ‘Definitions’ and ‘Driving Homeostasis’ sections

Learning Target: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms. Function: Maintaining Homeostasis Topic: The control of Blood Oxygen/Carbon Dioxide content during and after exercise Model: Concept Map

Essential Question: How and why does heart rate increase with exercise? – Class brainstorm: Tell me what you know about the relationship between heart rate and exercise – We will concept map this later

What is a Concept Map? A web of boxed terms/concepts connected by arrows Arrows are labeled with words that describe the connection between boxes Boxes should be connected so that the map can be followed in a logical way to organize ideas Here are examples of good concept maps:

Hyperthermia Heat receptors in the skin Hypothalamus Stress Sensors Control Center Increased activity of sweat glands Increased blood flow to the skin Effectors Effect ed Example: Homeostatic Regulation of Body Temperature through Negative Feedback – YOU ARE OVERHEATING!!! What happens? Stress is reduc shutting down mechanism Perspiration evaporates cooling the skin

Class Concept Map: Let’s generate a list of everything we know about heart rate and exercise and put it on a class concept map Think about how we maintain our homeostasis

Task: Make a concept map on diabetes and how blood sugar is regulated in your body Use our class concept map as a starting point You will read the article “How Diabetes Works” independently Develop a list of key concepts and words that should be included on your map Notes Section
