Abstract
Many would believe that respiration for life and speech are the same, however they are actually very different. In this composition, you will discover these differences. You will find the definition of respiration, what muscles are used in respiration, how these muscles are used, lung volumes and capacities, and how these are all used in life and speech. Respiration is the oxygenation of blood and the removal of carbon dioxide while breathing. It also helps in the production of speech sounds (phonation) for communication. Inhalation is the process in which the diaphragm lowers in order to let the lungs expand to draw air in the lungs to equalize pressure. Exhalation is the process by which the diaphragm is pressed against …show more content…

Efficiency of respiration depends on how an individual may control the muscles they use for respiration. Speech production is made possible only by the force made by respiration. You inhale and exhale through your mouth. In speech production inspiration is faster and expiration is more extended than respiration for life. We actively think about it. Inhaling takes about 10% of the cycle and exhaling takes about 90% of the cycle. The vital capacity depends on how loud you are, usually about 20-25%. (quizlet.com) In passive expiration, the system is restored to resting position after respiration. Torque, gravity, and elasticity are the driving forces of this action. In active expiration, there is muscular effort, muscles reduce the size of the thorax, the abdomen is compressed, the rib cage is pulled down, and air is pulled out of the …show more content…

The spinal column includes 12 thoracic vertebrae, 7 cervical vertebrae, 5 lumbar, sacrum, and coccyx. Intervertebral cartilages and ligaments join the vertebrae. Cervical vertebrae have transverse foraminae for vertebral arteries and veins. The basis for respiratory structure is provided by the thoracic vertebrae. The point of attachment for posterior fibers of the diaphragm are the lumbar vertebrae. The sacrum is fused sacral vertebrae. The coccyx is fused coccygeal vertebrae. The pectoral girdle consists of the clavicle and scapula. The pelvic girdle is paired hip bones along with the sacrum and coccyx. The rib cage is composed of 12 pairs of
