Muscles of ventilation 1. However, during exercise, many other muscles become important to respiration. Respiration can be anaerobic which involves glycolysis where glucose gets converted to pyruvate, creating 2 ATP. This muscle is also responsible for helping in expelling vomit, feces and urine by applying pressure in the abdomen. Answer: Explanation: Muscles of respiration: The muscles of respiration are those muscles that plays role in inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. Contraction of the diaphragm expands the abdomen and the lower part of the rib cage (abdominal rib cage). Even as you sit reading this article, all the cells of your body are producing a baseline level of carbon dioxide; the amount produced in this state determines your normal respiratory rate. (a) Glycolysis (b) Krebs’ cycle (c) Conversion of lactic acid to pyruvic acid (d) Conversion of pyruvic acicfcto acetyl Co-A 2. The act of respiration is involuntary, meaning people are not typically conscious of it. 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.
