is a measurement of the total amount of air that the lung can hold; normally it is 6 litters for adult male and 4.2 litters for an adult female. The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. The Residual Volume (RV) is the amount of gas remaining the lungs after a maximal expiration; normally it takes up 20% of the total lung capacity. VC + RC = TLC. The Inspiratory Reserved Capacity (IRC) is the amount of air that can be inhaled

It consists of three parts that consecutively explain the impact of Mohammad’s injuries and habits on his respiratory function‚ hemodynamics and arterial blood gases. Respiratory changes Normal tidal respiration is a two-phasic mechanical process embracing inhalation and exhalation. Inspiration is produced by contraction of inspiratory muscles‚ which increases the size of thoracic cavity

we are laying in bed asleep‚ sitting listening to a teacher‚ or walking down the hallway‚ the cardiovascular and respiratory systems work together to regulate oxygen and waste throughout the body. When an activity becomes strenuous for a prolonged period of time‚ these systems must adapt to increase the capabilities of oxygen and waste management. The main function of the respiratory system is the exchange of gases with

RESPIRATORY SYSTEM WEBQUEST 1. Describe the function of the nasal and oral pharynx for breathing. The ph arynx is a muscular funnel that extends from the back of the nose to the larynx‚ or voice box. The nasal pharynx’s function is to allow air passage through it. The oral pharynx has both respiratory and digestive functions since it serves as a passageway for air‚ food‚ and water. 2. Describe the structure and function of the epiglottis. The epiglottis is one of the nine cartilagous structures

Introduction:Spirometry is the classic pulmonary function test‚ which measures the volume of air inspired or expired as a function of time. It can monitor quiet breathing and thereby measure tidal volume‚ and also trace deep inspirations and expirations to give information about vital capacity. Spirometrymay also be used to measure forced expiration rates and volumes and to compute FEV1/FVC ratios. Spirometry provides an objective measurement of lung function. It will measure the Expiratory Vital
