Document Summary
Physiology is going from a organism level to a molecular level goal: explain physical and chemical function in how the body functions. Medical physiology or pathophysiology: abnormal physiology as a result of disease. Comparative, animal, or integrative physiology: how animals adapt to abnormal environments or life histories. Looking at heart failure due to insufficient oxygen supply. Animals can live at altitudes 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)connective tissue cells: connect and physically support body structures ex// bone, collagen, cartilage, fat cells blood: connects oxygen to the rest of your body: epithelial cells: secretion and absorption; protective roles. Exocrine glands: salivary glands (secrete to an external environment) Endocrine gland: adrenal gland (act on different systems internally via neurotransmission) Renowned french physiologist claude bernard was the first to use blind experimentation to remove bias.
