Translucent, Explain the theory of plate tectonics and how they have changed earths surface over time. However, the ability to breathe—to have air enter the lungs during inspiration and air leave the lungs during expiration—is dependent on the air pressure of the atmosphere and the air pressure within the lungs. Muscles of Respiration Various muscles of respiration aid in both inspiration and expiration, which require changes in the pressure within the thoracic cavity (Figure 27-6). Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly to bring in oxygen and flush out carbon dioxide.. All aerobic creatures need oxygen for cellular respiration, which uses the oxygen to break down foods for energy and produces carbon dioxide as a waste product. 1) [11,12,13]. The accessory inspiratory muscles are the sternocleidomastoid, the scalenus anterior, medius, and posterior, the pectoralis major and minor, the inferior fibres of serratus anterior and latissimus dorsi, the serratus posterior anterior may help in inspiration also the iliocostalis cervicis. The elasticity of these muscles is crucial to the health of the respiratory system and to maximize its functional capabilities.

Contraction of the diaphragm expands the abdomen and the lower part of the rib cage (abdominal rib cage). Contraction of diaphragm generates tension within its fibers, displacing the central tendon caudally. The diaphragm and intercostal muscles drive respiration during quiet breathing. These changes in volume result in changes in pressure that during inhalation result in air being pulled in from outside the body and during exhalation result in air being forced to the outside of the body. Consequently: A) pleural pressure falls, allowing air to flow into the airways and alveoli, thereby increasing lung volume; B) abdominal pressure increases, thus pushing the abdominal cavity downward, allowing the thorax to expand; C) the ribcage is lifted upwards and outwards by action of the scalenes and sternocleidomastoid on the sternum, and external intercostal muscles on the ribs. Respiration is the cellular process of breaking down chemical energy (substrates) to make ATP C6H12O6 + 6 O2 6 CO2 + 6 H20 + E Muscles of ventilation 1.
