4_Epiglottis Function (700 words) The epiglottis is located above the larynx. The function of the epiglottis is to protect the respiratory system from foreign particles‚ such as food. During swallowing‚ the epiglottis is depressed over the larynx. When breathing‚ it is open to allow air to travel freely. This article seeks to explain the function of the epiglottis and problems that may be associated with it. Epiglottis Function and Anatomy The epiglottis is formed by elastic cartilage and is

EFFECT OF ATMOSPHERIC PRESSURE ON THE ENVIROMENT THE BIOSPHERE Variations in atmospheric pressure can present special problems for the respiratory systems of animals because atmospheric pressure affects the exchange of oxygen and carbon dioxide that occurs during animal respiration. Normal atmospheric pressure at sea level is the total pressure that a column of air above the surface of the Earth exerts (760 millimetres of mercury‚ or 1 atmosphere)

courtney mcgregor THE RESPIRATORY SYSTEM The respiratory system is the biological system that introduces respiratory gases to the inside of the body and performs a gas exchange (o2 → CO2) through externaal respiration for bodily fuctions to operate. In humans and mammals‚ the anatomical features of the respiratory system include airways‚ lungs and plenty of muscle‚ nose‚ pharyngeal regions‚ larynx‚ and trachea. Five disorders that relate or effect the respiratory system are: Pulmonary HypertensionChronic
