Required Reading in
Biology: Concepts and Connections
(SIXTH edition) by Campbell et al.
Animal Form and Function
(Parts of Chapters 20, 21 and 25)
Give examples of how structure fits function in the animal body, especially
how form fits function
exchanges between animals and their environments (20.13).
Compare and contrast the specialized
structures used for food processing
(ingestion, digestion, absorption and
elinmination) in hydra, worms, grasshoppers, birds and mammals (21.2 and 21.3, Lab Guide Minicourse 1)
Contrast the three
forms of nitrogenous waste
excreted by animals -- ammonia, urea, and uric acid -- in terms of their
toxicity, solubility and chemical composition.
Cite the advantages and disadvantages of excreting each (25.5).
Trace the processing of filtrate through the nephron
of a human kidney, including the glomerulus, Bowman's
capsule, proximal convoluted tubule, descending and ascending portions of the loop of Henle, distal convoluted tubule,
and the collecting duct (25.6).
Describe each structure’s role in filtration, reabsorption, secretion or excretion (25.7 and
Explain the effects on
of antidiuretic hormone (ADH), ethyl alcohol and caffeine (Lecture).
Compare a kidney dialysis machine with a normal kidney (25.9)
What kinds of information about the body are provided by CT scans, magnetic resonance imaging (MRI), and positron
emission tomography (PET) scans (20.11)?
List four things necessary for gas exchange
to occur in multicellular animals and explain why each is required (Lab
Guide, Minicourse 2, p. 2).
Compare and contrast the systems used for gas exchange by various animals (22.2), including insects (22.4).
how the efficiency of gas exchange and transport has been improved
by respiratory pigments, red blood cells,
branched gas exchange surfaces, and internal transport systems (22.10 and 22.11).
Compare and contrast the structural organization and gas exchange efficiency of gills and lungs
availability of oxygen in water and air, countercurrent flow in gill filaments, and the structure of the alveolar sacs in
