Homeostasis and Osmosis Study Guide
Compiled by Pat Bowne, Sherry Dollhopf,and Justin LaManna, 2007-11
Human physiology and anatomy deals with the structure and function of the human body. Physiology in particular is the study of how the human body maintains homeostasis. We will begin our study by examining mechanisms of maintaining homeostasis. We will also begin to look at osmosis and membrane transport at the cellular level and how they are important in maintaining body fluid levels.
|Before class, make sure you:||
Can describe the general structure of eukaryotic cells and their membranes.
Can explain the difference between solutes and solvents
Can define lipids, proteins, and sugars
|Tutorials and reading assignment:||
Review the basics of osmosis by doing the: |
Osmosis tutorial Hole Chapter 3, pp. 101-103 (diffusion and osmosis)
Chapter 1, pages 16-19 (homeostasis)
|What you should know for the assessment:||
Be able to explain homeostasis, negative feedback mechanisms, and positive feedback mechanisms.
Be able to DESCRIBE and DIAGRAM the events involved in negative and positive feedback mechanisms.
Be able to USE the concept of osmosis to predict the movement of water and/or solutes across cellular membranes in human physiology examples.
Be able to MODEL the movement of water around the body as solutes move between compartments
Be able to APPLY osmosis to explain specific situations in case studies
1. ANSWER these questions for a situation in which there is too little water in the blood.
