Document Summary
Pekn 1p90 lecture 2 organization of the human body and homeostasis. Physiology is the study of how the body functions. How do we explain events that happen in the body: teleological approach why. Explains functions in terms of meeting a bodily need. To help warm up: mechanistic approach how. Explains function in terms of sequences of physical and chemical processes. Temperature-sensitive nerve cells detect a fall in temperature then signal to the brainetc. We know why things happen (teleological) because of observation, but we need to learn how (mechanistic) with experimental approach. Chemical (molecules) organelles - cellular tissue organ body system organism. Atoms (oxygen, carbon, nitrogen, and hydrogen = 96% of the body) Molecules (proteins, fats, cho, and nucleic acids) Cells the basic unit of structure and function in the body the smallest unit capable of carrying out the processes associated with life. The body is made of many types of cells, each with a specialized function.
