Respiratory System Physiology

QuestionAnswer
Model lung. In internal volume of the bell jar (thoracic cage) Diaphragm pushed up decreased and diaphragm pulled down increased
Model lung. In internal pressure Diaphragm pushed up increased and diaphragm pulled down decreased
Model lung. In the size of the balloons (lungs) diaphragm pushed up decreased and diaphragm pulled down increased
Under what internal conditions does air tend to flow into the lungs? (observation of model lung) increase in thoracic volume, decrease in pressure
Under what internal conditions does air tend to flow out of the lungs? Explain why this is so. (observation of model lung) decrease in thoracic volume, increase in pressure. Gases move in the direction that tends to equalize pressure inside and outside the container.
Volume of air present in the lungs after a forceful expiration. (respiratory volume term and normal value) residual volume (1100ml)
volume of air that can be expired forcibly after a normal expiration. (respiratory volume term and normal value) expiratory reserve (1200ml)
Volume of air that is breathed in and out during a normal respiration (respiratory volume term and normal value) tidal volume (500ml)
Volume of air that can be inspired forcibly after a normal inspiration. (respiratory volume term and normal value) inspiratory reserve (2700-2800ml)
Volume of air corresponding to TV + IRV + ERV. (respiratory volume term and normal value) vital capacity (4800ml)
Where are the neural control centers of respiratory rhythm? Medulla oblongata and pons
