Document Summary

Bioa02h3 lecture 1 (module 2): animal form and function. Physiological systems from a non-human perspective: very simple (basic to more complex neural networks, nervous and endocrine systems (command and regulation, circulatory (transport), respiratory (fluid regulation/defence) lymphatic (gas exchange) Physiological systems from a human perspective: muscular system (movement), skeletal system (support), integumentary system (defence, circulatory system (transport), lymphatic system (fluid regulation/defence), respiratory system (gas exchange, digestive system (digestion/absorption), excretory system (osmotic/ionic regulation) General themes in physiology: structure: function relationships, acclimatisation and adaptation, feedback/feedforward control systems, conformity and regulation. Structure: unction relationships: how does a structure or anatomy of an organ allow it to fulfill its physiological function, example: the fish gill is optimally designed for gas exchange. It is much more efficient than the mammalian lung. Feedback control systems: a physiological response to changing conditions (usually internal) to restore homeostasis, example: insulin release in response to high blood glucose (sugar) or glucagon release in response to low blood glucose.
