Study Notes
Major Parts of the Book
- The book is divided into six parts (I-VI), each focusing on specific animal physiological functions.
- Each part also includes an "AT WORK" chapter, using a synthetic approach to understand prominent topics within that part.
Animal Physiology
- Animals are dynamic systems, requiring energy for maintenance.
- Their atomic components constantly exchange with the environment.
- The organization of an animal's molecules is what persists through time, not the individual molecules.
- Animals constantly use energy to maintain their complex organization.
- Most cells reside in the animal's internal environment (e.g., tissue fluid, blood), not the external environment.
Internal Environment
- Animals may conform (allowing internal environment to match external) or regulate (maintain internal, constant environments).
- Regulation is more energy-intensive than conformity.
Homeostasis
- Homeostasis = internal constancy of conditions within an animal's body.
- Important concept related to regulation.
- Historical origins in studies of human blood glucose, emphasizing the importance of internal consistency.
- Key concept for understanding mammal and medical physiology.
Feedback Systems
- Negative feedback: Systems respond to changes in the controlled variable by reversing these deviations from ideal conditions.
- Positive feedback: Systems amplify the change from the set point. Less common in normal animal physiology.
Physiology over Time
- Animals alter their physiology in five time frames:
- Acute changes: Immediate responses to environmental changes.
- Chronic changes: Long-term responses to environmental changes.
- Evolutionary changes: Modifications across generations due to environmental adaptations.
- Developmental changes: Internal changes in an animal during growth until maturity.
- Changes controlled by circadian rhythms: Involving internal timekeeping mechanisms.
Animal Size and Traits
- Body size significantly impacts animal traits (e.g., gestation length).
- Statistical methods (e.g., regression) used to measure these impacts.
- Scaling studies examine predictable relationships between size and various physiological traits.
Environmental Factors
- Key environmental factors are temperature, oxygen, and water.
- Temperature conformity: Organisms whose internal temperatures match external.
- Temperature regulation: Organisms maintain internal temperature, regardless of external changes.
- Animals living in frigid climates often exhibit remarkable adaptation.
- Oxygen availability varies greatly in the environment (air vs. water, high altitude vs. sea level).
- Microenvironments: Local variations within a larger environment (e.g., inside a burrow vs. surface in a desert).
Breathing by Various Animals
- Fish: Rely on countercurrent exchange in gills for efficient gas exchange.
- Amphibians: Have varied respiratory mechanisms (gills, lungs, skin), that change during their development.
- Reptiles: Typically use lungs for gas exchange. The lungs can be unicameral or multicameral.
