PPT-DRUGS AFFECTING THE RESPIRATORY SYSTEM

Dr AShyam Sundar Associate Professor in Pharmacology University of Nizwa Sultanate of Oman OVERVIEW Asthma is a reversible obstructive disease of the lower airway With asthma there is increasing airway obstruction caused by bronchoconstriction inflammation and edema of the lining of the bronchioles and the production of thick mucus that can plug the airway.

Oxygen . to the cells and remove the waste product . Respiratory System. Air sac. air-filled spaces in the body. alveoli. very small air sacs; where air breathed in goes. Respiratory System. Bronchial tubes. two tubes at the end of the trachea, brings in air from trachea and helps clean lungs; one tube goes to right lung, one to left. Transports air into the lungs and facilitates the diffusion of oxygen into the blood stream. Receives carbon dioxide from the blood and exhales it. Organs of the Respiratory system. Slide 13.1.

List drugs used in the treatment of respiratory disorders. Recall vital information about the drugs used in respiratory disorders. Chapter 14 Drugs Affecting The Nervous System The nervous system controls, directs and coordinates bodily functions 2 main divisions of the nervous system: Central Nervous System (CNS) - brain and spinal cord I.

Alteration in respiratory function. Living cells need energy for maintenance, growth, defense & replication. Human cells obtain that energy through aerobic mechanisms that require oxygen & produce carbon dioxide.. Humans respiratory exchange surfaces are confined to the inside of the lungs (in a warm, moist, protected environment) under these conditions, diffusion can occur between the air and blood.. By. Dr..

Birds having relatively small lungs plus nine air sacs that play an important role in respiration .
