A&P Theory Exam 1. Define life and the key components necessary for living systems to exist: PG 3 - Responsiveness: also known as irritability, this is how your body responds to harmful reactions (moving your hand away from a hot stove) organisms respond to changes in their immediate environment. Another example would be animals migrating in colder weather, winter coats being grown by animals to provide them better insulation in the winter. The capacity to make these adjustments is termed adaptability. - Growth: Organisms increase in size through the growth or addition of cells. Single celled creatures grow by getting larger. More complex organisms grow by increasing the number of cells. As such multicellular organisms develop, individual cells become specialized to perform particular functions, this specialization is known as DIFFERENTATION. - Reproduction: Organisms reproduce, creating new generations of similar, but not identical organisms. - Movement: Movement can be internal (transporting food, blood, or any materials within the body) or movement can be external (moving through the environment) - Metabolism: Organisms rely on chemical reactions to provide the energy required for responsiveness, growth, reproduction and movement. Metabolism is all the chemical operations in the body. Identify the relationship between Anatomy and Physiology and their subdivisions - Physiology is the Study of the function of the human body and how living organisms carry out their vital functions. (PG 4) o Cell physiology- The study of the functions of living cells, includes events at the chemical or molecular levels, chemical processes both within and between cells. o Special physiology- The study of the physiology of specific organs (Ex: kidney function and heart function) o Systemic physiology- Considers all aspects of the function of specific organ systems, respiratory and reproductive physiology are examples. o Pathological physiology- Study of the effects of the diseases on organ or system functions. - Anatomy: The study of internal and ext
