ASSIGNMENT 07 H05 Anatomy & Physiology II Directions: Be sure to save an electronic copy of your answer before submitting it to Ashworth College for grading. Unless otherwise stated, answer in complete sentences, and be sure to use correct English, spelling and grammar. Sources must be cited in APA format. Your response should be four (4) double-spaced pages; refer to the "Assignment Format" page located on the Course Home page for specific format requirements. After completing this assignment you will be able to: • • • Explain the basic concepts involved in fluid and electrolyte regulation Explain the different buffering systems of the intracellular and extracellular fluid Understand how homeostasis may be disrupted if the appropriate balance of body fluids is not maintained 1. Describe the differences between intracellular fluid (ICF) and extracellular fluid (ECF) including: a. Location in the body b. Characteristic ions 2. Sodium and potassium are the largest contributors to electrolyte balance in the body. Describe one (1) way in which they each participates in electrolyte balance in the body. 3. The composition of body fluids is extremely important to maintaining homeostasis in the body. Discuss three (3) ways that homeostasis may be disrupted if the appropriate electrolyte levels and pH of body fluids are not maintained. Describe two (2) solutions that are available to return the body to homeostasis. Grading Rubric Please refer to the rubric on the following page for the grading criteria for this assignment. CATEGORY ICF vs. ECF (20 points) Exemplary 20 points Student provides a clear, logical description of the differences between intracellular fluid (ICF) and extracellular fluid (ECF) including location in the body and characteristic ions. Satisfactory 15 points Student provides a mostly clear, logical description of the differences between intracellular fluid (ICF) and extracellular fluid (ECF) including location in the body and characteristic ions. Unsatisfactory 10 points Student provides a partially clear, logical description of the differences between intracellular fluid (ICF) and extracellular fluid (ECF) including location in the body and characteristic ions. Unacceptable 5 points Student provides a partially clear, logical description of the differences between intracellular fluid (ICF) and extracellular fluid (ECF) including location in the body and/or characteristic ions. 8 points 5 points Student provides a partially Student provides a clear, logical description of partially clear, logical at least 1 way that sodium description of at least 1 participates in electrolyte way that sodium balance and at least 1 way participates in electrolyte that potassium participates balance and/or at least 1 in electrolyte balance. way that potassium participates in electrolyte balance. Electrolyte balance 15 points (15 points) Student provides a clear, logical description of at least 1 way that sodium participates in electrolyte balance and at least 1 way that potassium participates in electrolyte balance. 12 points Student provides a mostly clear, logical description of at least 1 way that sodium participates in electrolyte balance and at least 1 way that potassium participates in electrolyte balance. Homeostasis disruption (20 points) 20 points Student provides a clear, logical description of at least 3 ways that homeostasis may be disrupted if the appropriate electrolyte levels and pH of body fluids are not maintained. 15 points Student provides a mostly clear, logical description of at least 2 ways that homeostasis may be disrupted if the appropriate electrolyte levels and pH of body fluids are not maintained. 10 points Student provides a partially clear, logical description of at least 1 way that homeostasis may be disrupted if the appropriate electrolyte levels and pH of body fluids are not maintained. 5 points Student provides a weak or unclear description of at least 1 way that homeostasis may be disrupted if the appropriate electrolyte levels and pH of body fluids are not maintained. Solutions (20 points) 20 points Student provides a clear, logical description of at least 2 solutions that are available to return the body to homeostasis. 15 points Student provides a mostly clear, logical description of at least 2 solutions that are available to return the body to homeostasis. 10 points Student provides a partially clear, logical description of at least 1 solution that is available to return the body to homeostasis. 5 points Student provides a weak or unclear description of at least 1 solution that is available to return the body to homeostasis. Mechanics (15 Points) 15 points Student makes no errors in grammar or spelling that distract the reader from the content. 12 points Student makes 1-2 errors in grammar or spelling that distract the reader from the content. 8 points Student makes 3-4 errors in grammar or spelling that distract the reader from the content. 5 points Student makes more than 4 errors in grammar or spelling that distract the reader from the content. 8 points The paper is written in proper format with only 1-2 errors. All sources used for quotes and facts are credible and most are cited correctly. 5 points The paper is written in proper format with only 3-5 errors. Most sources used for quotes and facts are credible and cited correctly. 2 points The paper is not written in proper format. Many sources used for quotes and facts are less than credible (suspect) and/or are not cited correctly. Format (10 Points) 10 points The paper is written in proper format. All sources used for quotes and facts are credible and cited correctly.
