2. General review Organs When two or more tissues combine in such a manner as to exhibit functional unity they form an organ. By definition and organ is somewhat independent part of the body that performs a special function.

3. Systems When two or more organs combine in such a manner as to exhibit functional unity they are commonly called systems. There are at least nine recognized systems in the body: 1.Skeletal system 2.Articular system 3.Muscular system 4.Digestive system 5.Vascular system 6.Nervous system 7.Respiratory system 8.Urinary system 9.Generative or productive system 10.Endocrine system 11.Integumentary system

4. Intro to Speech Mechanism Speech production consisting of four phases: respiration, phonation, articulation, and resonance. These four parts are most closely associated with speech production include the lungs, trachea, larynx, nasal cavities and the oral cavity.
