Forward control and homeostasis initiation of a response in anticipation of the stimulus: ex/ sight, smell or thought of food initiate salivation and digestion, ex/ beginning an exercise (not during) increased breathing. Describe biological hierarchy of organization in the context of compartments (molecules cells tissues organs organ systems organism) Compartments are separated by membranes (i. e. pericardial membrane around the heart, made of a layer of flattened cells supported by connective tissue, each cell has their own membrane made of phospholipid bilayers)
