Document Summary
4 main types of cells in the body (think: mnec ; 1. 2): Muscle cells: specialized for contraction to produce movement. Nerve cells: generate and propagate electrical signals epithelial">epithelial cells: secretion and absorption (epithelial tissue consists of a sheet-like layer) Claude bernard came up with the idea that mammals have an ability to regulate their. In cold conditions, a mammal will lose heat through the skin as a result, muscle contractions increase (friction produces heat) The maintenance of static or constant conditions in the internal environment . 1. 4 shows a simplified view of the human body. Note that the lungs, gastrointestinal (gi) and urinary tracts are exposed to the external. Mixing between compartments occurs as a result of the semipermeability of cell membranes and epithelial tissues. The following values are for a person weighing 150 lbs. (70 kg): Intracellular fluid (icf): 28 l fluid inside cells. Extracellular fluid (ecf): 14 l all fluid outside cells.
