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.
