Document Summary

Homeostasis, signal pathways, feedback loops, osmosis, tonicity, body fluid: why is physiology exciting basic science for medicine explains diseases, suggests treatment for diseases, frontier of biomedical research, tells us how cells communicate, exercise and sports. Organ systems that will be covered: urinary/reproductive, endocrine, nervous, musculoskeletal muscle physiology, circulatory system. Le chatelier"s principle (law of mass action: if a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure then the equilibrium shifts to counteract the imposed change and a new equilibrium is established. Homeostasis (stability of the body"s internal environment: claudie bernard, mid 1800s. Conditions inside the body are different than conditions outside the body. Sum of conditions inside the body is called milleu interior . In different compartments inside the body conditions are different from other compartments: water and cannon, 1929. Maintenance of relatively constant conditions inside the body is called homestasis homeostasis does not mean equilibrium. Keeping a constant difference = homestasis mmol/l.
