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.
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
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.

• Speech production phases:
1- Respiration/breathing
2- Phonation
3- Articulation
4- Resonance.
