BIOL 2457 Lecture Notes - Lecture 4: Anatomy 2, Cellular Respiration, Integumentary System
Document Summary
Molecular- include proteins, carbs, nucleic acids and lipids. Tissue- collection of cells that have a similar function (epithelium, nervous, muscular and connective tissue) Organ- discrete structure that has at least 2 tissue types (kidneys) Organ system- group of organs that work together to perform a multitude of functions. Organism- collection of body systems that work together to keep the organism alive. 1. complementarity of structure and function: function reflects the underlying structure b. In order to understand physiology, one must understand anatomy. 2. body organ systems interact with each other: most physiological processes depend on interactions between several organ systems. 2. it"s all about homeostasis: deviations from homeostasis can lead to significant changes in physiology, to understand physiology, one must study the physiological responses when homeostasis is deviated from. All body cells are interdependent and, therefore, so are the organ systems. Vital functions: separation of internal/ external environments (skin; helps maintain body temp bc of the keratin keep.
