Important Homework announcements

Due at the beginning of class, written by hand (paper and pencil or pen).

Read ahead

Before class, you can prepare by reading the following materials:

  1. Monday and Wednesday we will finish respiration and Friday begin osmoregulation.
  2. The Symmorphosis paper is a very interesting and important paper. It will be useful for design3 respiration.
  3. In Lab this week you will measure your own brain waves using EEG. Have fun! [manual]!

Announcements/Reminders

  • Due Monday at the start of class– Homework 5 [schedule]
  • Due Friday at midnight - Design 3 draft
  • Please do your peer review for design 3 over the weekend
  • Do discussion TEAMMATES eval, released each Friday, due by Monday.

Monday - Finish aerial respiration questions 2, 3, 5

  • Reading assignment: Withers pp. 609-631 OR HWA chapter 23 + Withers 626-632, skip invertebrates
  • [discussion pg 4:2,3,5] [slide deck2]
  • Aerial Respiration Topics:
    • Air flow patterns of vertebrates
    • Lung Volumes
      • Lung Volume (VL or VT)
      • tidal volume (Vt)
      • Dead space volume (VD)
      • Alveolar ventilation volume (VA or Va)
      • Alveolar Minute Volume (VAE)
    • Breath Rate (BR)
    • Oxygen Extraction and Pulmonary Diffusing Capacity

Respiration the Movie

Wednesday - Symmorphosis

  • Reading assignment: Symmorphosis: Weibel, Taylor, and Hoppeler (1991) The concept of symmorphosis: A testable hypothesis of structure-function relationship. PNAS 88:10357-61 Respiration Papers folder
  • In class discussion

Friday - Begin Osmoregulation

  • Reading assignment: Withers skim beginning Ch. 16 for definitions in list below, also read Water & Ion Budgets pp. 788-790, Vertebrates pp. 798-803, Terrestrial Environments pp. 806-812, Terr. Verts. 822-827. Withers is actually very readable on this topic, and some of it will be familiar to you already:).
  • [discussion] [slide deck] [slide deck 2]
  • definitions:
    • solutes,
    • osmosis,
    • osmolarity/osmolality,
    • ionoregulation,
    • osmoregulation/osmoconforming,
    • compatible solutes,
    • perturbing solutes,
    • counteracting solutes,
    • osmotic permeability (&formulae)
  • The components of Water Budgets (input/output) as well as Ion Budgets
  • The water and ion challenges of freshwater, marine, and terrestrial environments
