BIO 342 HUMAN PHYSIOLOGY
• PHYSIOLOGY: The study of the function of cells, tissues, organs, and organ systems.
• THE TEXT: Widmaier et al. 2011 (12th ed.) & 2014 (13th edition)– Chapter 2-5 review of other courses– Using your textbook– Using chapter questions from
Website
The Syllabus (on the course website
http://webs.wofford.edu/davisgr/bio342/)and Moodle Site for Grades and Electronic Assignments
• Office & cell phone numbers• E-mail (davisgr@wofford.edu)• Lecture topics by week
– Text chapters in parentheses– Read in advance of lectures– Check Moodle site 3x/wk at least
LABORATORIES• May shift topics due to availability of animals• One Lab Report in the form of abstracts
– very concise, based on lab data– Incorporate statistics– With revision and resubmission
• No separate lab tests; lab material included on lecture tests
GRADING• 3 lecture tests = 60%
– multiple multiple choice (choose all correct answers)– Some short answer in the space provided– Rarely fill in the blank– Sometime create or complete graph or diagram– discussion question(s) from a list
• Cumulative final exam = 20%• Other work = 20%
– Abstract = 10% – 1 Question Quizzes (1QQs) and other assignments = 10%
Honor Code
• All worked is “pledged.”• Issues of plagiarism to be handled by the
Honor Court.• Work together, but submit your own work.
ODDS AND ENDS
• Limited use of electronics in classroom & lab– Only for class/lab-related activities
• NO FOOD or DRINKS in Lab • BE ON TIME, READY TO GET TO WORK• DON’T ASK ABOUT LENGTH OF LAB• BE READY TO START ON TIME• RECORDING LECTURES BY PERMISSION WITH LIMITS
Study Questions & Quizzes
• Questions provided for each chapter (On the website!)
• Read the book and answer the questions PRIOR to class meeting
• Class time is used to deal with problematical topics and reinforce the major concepts
• Be ready for 1QQs
Study Questions & Quizzes
• Rationale for this format:– See what Dr. Davis thinks you ought to emphasize– Writing helps to consolidate memory and recall– Greater effort results in better retention and
understanding– Students are engaged learners– Able to cover more information
Improve MCAT, DCAT and GRE scores
Sample 1QQName on top edge, back side of paperAnswer on blank side of paper.
1.The 200+ cell types in the human body can be classified into one of 4 cell types or tissue types. List the 4 types and their distinguishing characteristics.
2.List the 4 modes of heat exchange and provide an example of one of those modes.
3.What is the difference between an organ and a tissue?
Cognitive Domain (Revised Bloom) Description Action verbs Original Bloom’s term
1.Remember (LOCS)** Retrieve relevant knowledge Recognize, identify, recall, list, label Knowledge
2. Understand (LOCS) Describe meaning Interpret, exemplify, classify, summarize/explain/describe in own words
Comprehension
3. Apply (LOCS/HOCS) Use/apply procedures or info in novel context Execute, predict Application
4. Analyze (HOCS) Infer relationships between components or parts and bigger picture Differentiate, organize, link, attribute, infer, interpret, diagnose, compare/contrast, conclude, speculate Analysis
5. Evaluate (HOCS) Make judgments based on evidence, criteria, and standards Verify, critique, assess merit Evaluation
6. Create (HOCS) Piece together info to form novel whole; create original product Generate, plan, build, produce, design, model Synthesis
A Taxonomy of Cognitive Skills for Developing Student Assignments and Assessments**SC SDE (Pat Mohr). Adapted from Lorin W. Anderson, David R. Krathwohl et al (Eds.) A Taxonomy for Learning, Teaching, and Assessing: A Revision of Bloom’s Taxonomy of Educational Objectives 2001; modified by Ellen Goldey, Wofford College, to incorporate “Biology in Bloom,” Crowe et al., 2008, CBE – Life Sci Edu., 7: 368-381. **HOCS = higher order cognitive skills, LOCS = lower order cognitive skills.
More stuff
• Arrive early for lecture and lab• Pay attention (no cell phones, email, Facebook, etc.
during lecture or lab)• Take notes on what is said….don’t wait for
boardwork.• Powerpoints usually posted AFTER lecture• Drop by the office for a visit!• Complete the Personal Information Sheet on the
Moodle site and submit it electronically to Moodle.

Even More Cell Types ( page 3)

densa• Chromaffin cell of the
adrenal medulla
• Parafollicular cell of the thyroid
• Cell of the collecting duct in the kidney
• Secretory cell of the zona glomerulosa in adrenal cortex
• Secretory cell of the zonal fasciculata in adrenal cortex
The Human Body:A Society of Cells
• Imagine you are a cell. Ask yourself:• Which category of cell am I? (Epithelial, Connective, Nervous, or Muscle)• What are my special characteristics and functions that distinguish me from
all other cell types? (This is what makes me unique!) • What do I do for the person in whom I reside? What are my contributions
to the whole organism? To homeostasis? • What do I need to survive?• In what ways do I depend on other cells?• What governs my actions? • Where did I come from? How long will I live?• What would happen to the organism if I along with all the other cells of my
type were to fail to function properly?
Answer as many of the above questions as you can and provide your sources. Submit your essay to the Moodle Site by midnight Sunday, Sept 8.
Bring a printout to class on Monday, Sept 9th.
O2
Cell Membrane: selectively permeable
Capillaries: highly permeable except to proteins
Homeostasis:
• The relative constancy of the internal environment
• Steady state vs. equilibrium

First section: the importance of temperture….. thermoregulation
Second second: the importance of fuel molecules …. Glucose homeostasis
