Document Summary
Physiology - is the study of the functions of living things- how the human body works. Technological approach: explaining body functions by bodily need: why? or purpose of function. Mechanistic approach: explaining actions in terms of cause and effect with physical and chemical reactions example: shivering; when temperature sensitive nerve cells detect a fall in temperature they signal the area in the brain responsible for temperature regulation. In response, this brain area activates nerve pathways that bring the involuntary, oscillating muscle contractions. Physiologists explain how events occur in the body. It is helpful to think of which body part would be used for certain functions, therefore logically reason what would happen in a situation. Anatomy: the study of the structure of the body. Chemical level atoms, are the building blocks, most common in the body: oxygen, carbon, hydrogen, nitrogen (96%) calcium, phosphorus, and potassium contribute 4 % these combine to form molecules such as proteins, carbohydrates, lipids, dna (nucleic acids)
