Document Summary
Gross or macroscopic (e. g. , regional, systemic, and surface anatomy) Overview of anatomy and physiology (e. g. , renal or cardiovascular physiology) Body"s abilities depend on chemical reactions in individual cells. What a structure can do depends on its specific form. Organ: contains two or more types of tissues. Stability of internal environment= condition of a free and independent life . Maintenance of relatively stable internal conditions despite continuous. Involve continuous monitoring and regulation of all factors that can. Nervous and endocrine systems accomplish communication via nerve. 2013 pearson education, inc. impulses and hormones. Responds to stimuli (something that causes changes in controlled variables) Determines set point at which variable is maintained. Response either reduces (negative feedback) or enhances stimulus (positive feedback) Variable changes in opposite direction of initial change. Regulation of body temperature (a nervous system mechanism) Regulation of blood volume by adh (an endocrine system mechanism) Control center in hypothalamus stimulates pituitary gland to release.
