Description Building on the underlying physical and chemical principals/laws that define physiology, this unit from both a systems (e.g. Respiratory) and environmental (e.g. Marine) perspective, seeks to compare the functional physiology of organisms at all levels of organisation. Particular attention will be paid to respiration, temperature tolerance & regulation, living in water, sensory and neurophysiology. Students will have the opportunity to carry out a defined research project.

Learning Outcomes

On successful completion of this subject, students should be able to:
  1. Describe and compare between the different respiratory, excretory and circulatory systems utilised by organisms and discuss how physiological adaptations allow organisms to inhabit extreme environments (eg. deserts & freezing habitats).
  2. Explain the mass scaling laws with a particular focus on metabolism.
  3. Describe the physiological adaptations that organisms exhibit living in water with reference to osmoregulation, buoyancy and diving.
  4. Explain the similarities and differences with phyla in terms of their neurophysiology and sensory organs.
  5. Explain how different organisms achieve locomotion (movement) and obtain their nutritional requirements (feeding).
  6. Conduct both independent and group investigations safely and ethically in the field and laboratory, using sampling methodology correctly to obtain valid data.
  7. Use spreadsheets and statistical tools in analytical programs to enter, analyse and graph data, as to draw appropriate conclusions from data.
  8. Communicate findings correctly in oral or in written form using an appropriate style, as well as accessing the scientific literature to place the findings in context.

Subject Content

1. The integrative (multidisciplinary) nature of physiology and its determination by basic physical and chemical principals/laws;
2. The diversity of respiratory (including respiratory pigments) and circulatory systems;
3. Nutrition and the different modes of feeding that exist;
4. Scaling laws and metabolism;
5. The physiological adaptation of organisms to extreme environments (deserts & freezing habitats) including the role of torpor;
6. Comparison of nitrogenous excretion across the phyla (ammonia, urea & uric acid);
7. Movement: types of skeleton, muscle and motility;
8. The adaptation of animals to living in water (buoyancy, osmoregulation & diving);
9. Neurophysiology & the diversity of sensory organs and structures exhibited by animals.
