Document Summary
Physiology is going from a organism level to a molecular level goal: explain physical and chemical funcion in how the body funcions. Medical physiology or pathophysiology: abnormal physiology as a result of disease. Comparaive, animal, or integraive physiology: how animals adapt to abnormal environments or life histories. Looking at heart failure due to insuicient oxygen supply. Animals can live at alitudes of 5000m with o2 levels less than 1/2 of sea level oxygen. Northern elephant can breathhold dive for over an hour. In the brain there are many phenotypes of neurons. 3)connecive issue cells: connect and physically support body structures ex// bone, collagen, carilage, fat cells blood: connects oxygen to the rest of your body: epithelial cells: secreion and absorpion; protecive roles. Exocrine glands: salivary glands (secrete to an external environment) Endocrine gland: adrenal gland (act on diferent systems internally via neurotransmission) Renowned french physiologist claude bernard was the irst to use blind experimentaion to remove bias.
