Dead Space Ventilation: Function, Tasks, Role & Diseases

Pulmonary respiration-also called ventilation-is composed of two components: alveolar ventilation and dead space ventilation. Dead space ventilation is the portion of the respiratory volume that is not involved in the exchange of carbon dioxide (CO2) for oxygen (O2). Dead space ventilation occurs because the volume of air that is in the upstream system of the … Dead Space Ventilation: Function, Tasks, Role & Diseases

Retraction Force: Function, Tasks, Role & Diseases

The term retraction force refers primarily to the lungs or thorax and means their tendency to contract when stretched, creating the intrathoracic negative pressure. Lungs get their retraction force from elastic fibers and surface tension of alveoli. The retraction force of the lungs is crucial for respiration, especially in the sense of expiration. What is … Retraction Force: Function, Tasks, Role & Diseases

Respiratory Rest Position: Function, Tasks, Role & Diseases

The respiratory rest position exists when the opposing retractive forces of the thorax and lungs reach equilibrium and the compliance or distensibility of the lungs is at its highest. In the respiratory rest position, the lungs contain only their functional residual volume. When the lungs are overinflated, the respiratory rest position changes in a pathologic … Respiratory Rest Position: Function, Tasks, Role & Diseases
