this test they assess 3 things to see the efficacy of the lung; 1- Lungs’ surface area with contact diffusing alveoli which is "alveolar volume". 2- Thickness of alveolar-capillary membrane. 3- blood volume available in the pulmonary capillaries. Physiology: In normal lung the gas exchange occur by passive diffusion of the gas via the alveolar-capillary membrane following Fick’s law of diffusion which is : D = (∆P x A x S ) ÷ (√MW x T) ∆P = the pressure gradient of partial pressure of CO in the

ABSTRACT Background: Pulmonary function testing is a routine procedure for the assessment and monitoring of respiratory diseases. Aim: To estimate the values of peak expiratory flow rate (PEFR)‚ forced expiratory volume in first second (FEV1)‚ forced vital capacity (FVC) and ratio between FEV1/FVC among smoking and nonsmoking students‚ staff and workers at Al-Zarqa

volume is the amount of gas that remains in the lungs and the passageways of the respiratory system even after a full exhalation. This gas never leaves the respiratory system; if it did‚ the lungs and respiratory passageways would collapse. The residual volume has little value for gas exchange because it is not exchanged with air from outside the body. Purpose In this activity‚ you will measure your own respiratory volumes using a device called a spirometer. Materials • spirometer with disposable

The equation of anaerobic exercise is:- Glucose → Lactic acid + Energy Lactic acid is produced as a waste product of anaerobic respiration and is what causes aches in muscles after exercise. The Respiratory System The respiratory system is made up of three major areas. The first is the airway which consists of the nasal cavity‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ bronchi‚ bronchioles and alveolus. The airways job

He is using an inhaled ß2 agonist and theophylline to manage his respiratory disease. At this clinic visit‚ it is noted on a chest x-ray that R.S. has an area of consolidation in his right lower lobe that is thought to be consistent with pneumonia. Discussion Questions 1.

The subject is a non-smoker and although she has never had any respiratory issues‚ asthma does tend to run in her family on the maternal side. The subject does however admit to feeling out of breathe easily when doing intense exercise for an extended period of time. B. Effect of CO2 on Breathing How did the

The cough reflex is a deep and long inhalation that is followed by the closing the glottis‚ this causes a strong exhalation that will push the glottis open and sends the air through the respiratory passage. The coughing occurs when a foreign body is in the larynx‚ trachea or the epiglottis. Cari is coughing because the
