BIOS10162 Lecture Notes - Lecture 1: Veterinary Medicine, Comparative Physiology, Heat Stroke
Document Summary
The study of organs and organ systems: today. Populations, organisms, organ systems, organs, cells, organelles, membranes, behavior, development. Why study non-human, non-mammalian species: to gain evolutionary perspective. Show how it got the way it is. Help people understand how it works and why: basic knowledge of how nature works, mammals are a small portion. Insects equal 70% of species: therefore, we should use comparative physiology, the krogh principle . For every physiological problem, there is an animal optimally suited to yield and answer. Understanding physiology of your research organism is imperative. Respiratory and vascular physiology, etc, of many different animals. Organ systems: cells, tissues, organs, and physiological systems, cells grouped together with the same characteristics or specializations are called tissues, the four basic types. Nervous: an organ is composed of all four types of tissue. Viii. neural tissue: neurons and glial cells, neurons. Lungs: external environments, varies a lot, terrestrial. Temperature, gas content, humidity, water, mineral, light: aquatic.
