Document Summary
Anatomy is the study of the structures of the body. Systemic anatomy is the study of the body by organ systems. Regional anatomy is the study of the body by areas. Surface anatomy uses superficial structures to locate deeper structures, and anatomical imaging is a noninvasive method for examining deep structures. Physiology is the study of the processes and functions of the body. Structural and functional organization of the human body. The human body can be organized into six levels: chemical, cell, tissue, organ, organ system, and organism. The eleven organ systems are the integumentary, skeletal, muscular, lymphatic, respiratory, digestive, nervous, endocrine, cardiovascular, urinary, and reproductive systems (see figure 1. 3). The characteristics of life are organization, metabolism, responsiveness, growth, development, and reproduction. Homeostasis is the condition in which body functions, body fluids, and other factors of the internal environment are maintained within a range of values suitable to support life. Positive-feedback mechanisms make deviations from normal even greater.
