PHSI 208 Lecture Notes - Lecture 1: Major Trauma, Feedback, Clearance Rate
Document Summary
Internal environment: dynamic steady state, control systems. Emergent properties = a property of a complex system has, but which the individual members do not have: due to complex, non-linear interactions of different components, e. g. emotions in humans, the genome project. Complex properties cannot be explained by the whole system, you have to break it down. Transport of materials b/w all cells of the body. Conversion of food into particles; elimination of pancreas some wastes. Coordinate body functions through synthesis and release of regulatory molecules. Thymus, spleen, lymph nodes defense against foreign invaders. Coordination of body functions through electrical signals and release of regulatory molecules. Cells need oxygen and the rbcs bring it to them. Oxygen bind to hemoglobin molecules in the rbcs. Translational research = uses the insights and results gained from basic biomedical research on mechanisms to develop treatments and strategies for preventing human diseases (cid:862)(cid:271)e(cid:374)(cid:272)h to (cid:271)edside(cid:863)
