which affect the system with a special focus on asthma. A BRIEF HISTORY OF THE STUDY OF RESPIRATION Hippocrates "counted air as an instrument of the body" just as food was eaten. Galen (129-200) felt that respiration served a triple purpose: 1) breathing cooled the heart‚ 2) air needed for production of vital spirits 3) respiration got rid of the friligimous or products of the innate fire burning in the heart. Basically Galen’s ideas were followed for many centuries until the era of the 17th century

HOW TO GO FROM STRESSED ~ TO UNSTRESSED! FEELING STRESSED? YOU’RE NOT ALONE “Stress” is our body’s normal‚ automatic response to change in our lives. The change may be negative‚ positive‚ or imagined. When we feel unable to cope with a new demand‚ we begin to feel stress. Stress is highly individual ~ what may be very relaxing to one person may be stressful to another. Not all stress is bad. We need a certain amount of stress in our lives because it stimulates and energizes us. At low levels‚

Bowel injury is associated with potentially life threatening consequences if not promptly recognized and treated. Immediate intraoperative repair is recommended because diagnosis of an unrecognized bowel in postoperative period is difficult. Early imaging with computerized tomography (CT) of the abdomen and pelvis is vital‚ and immediate surgical exploration is required when a bowel injury has been identified. Bishoff et al. performed a retrospective review in 915 patients who underwent laparoscopic

these passes is to make the muscles weak or paralyzed in surgery. Neuromuscular blockers can be used in many surgical procedures‚ like inserting an endotracheal tube‚ by relaxing the jaw muscles. They are also useful for relaxing the diaphragm and intercostal muscles (responsible for respirations) so that the patient can be manually ventilated. Neuromuscular blockers also aid in relaxing any muscles around the surgical site so that retracting for exposure is made easier. Broadly speaking‚ neuromuscular

he Respiratory System Fig 4. Horse’s respiratory system The functions of the respiratory system are to provide the body with oxygen‚ to remove carbon dioxide from the body‚ to control temperature (breathing out warm air and breathing in cool air)‚ to eliminate water‚ to communicate (Voice production) and sensory input (Smell/ touch- nose hairs). The respiratory system consists of the nostrils‚ pharynx‚ larynx‚ Nostrils The nostrils expand to allow air to enter the respiratory system‚ hairs within

The respiratory system provides life giving oxygen to cells through inspiration of air; at the same time‚ it removes carbon dioxide waste from cells through expiration‚ which can be lethal if not ventilated properly. This process is called pulmonary ventilation and is facilitated by three major components of the respiratory system: airways‚ lungs‚ and muscles; all of which play a vital role in the respiratory cycle and homeostasis. The respiratory cycle begins in the airways and during inhalation
