the respiratory system

1. the respiratory system

2. Humans breathe air into paired lungs through the nose and mouth during inspiration. Whilst air is in the lungs gaseous exchange takes place; in this process oxygen enters the blood in exchange for carbon dioxide. During expiration, air containing less oxygen and more carbon dioxide leaves the body. The oxygen obtained through gaseous exchange is required by body cells for cellular respiration, a process that releases energy from food.

12. Clinical Aspects of Respiration

13. Pneumonia is caused by several different microorganisms, most commonly bacteria and viruses. • Pneumonia is also applied to inflammation of the lungs caused by noninfectious causes, such as asthma, allergy, or inhalation of irritants. • Tuberculosis Infection disease caused by bacili causing small lesions in the lungs or other ogans Pneumonia

14. Attacks of asthma result from narrowing of the bronchial tubes. This constriction, along with edema (swelling) of the bronchial linings and accumulation of mucus, results in wheezing, extreme dyspnea (difficulty in breathing), and cyanosis. Asthma

15. Chronic irritation and inflammation caused by inhalation of dust particles Thisis an occupational hazard seen mainly in people involved in the mining and stoneworking industries. Pneumoconiosis

16. Respiratory distress syndrome of the newborn, also called hyaline membrane disease, occurs in premature infants and is the most common cause of death in this group. It results from a lack of surfactant in the lungs, which reduces compliance. Respiratory Distress Syndrome (RDS)

17. Pleurisy, also called pleuritis Is an inflammation of the pleura, usually associated with infection. Pain is the common symptom of pleurisy. Because this pain is intensified by breathing or coughing, as the inflamed membranes move, breathing becomes rapid and shallow Pneumothorax As a result of injury, infection, or weakness in the pleural membrane, substances may accumulate between the layers of the pleura. When air or gas collects in this space, the condition is termedPneumothorax Hemothorax Presence of blood in the pleural space Disorders Of The Pleura

18. Cystic fibrosis (CF) is the most common fatal hereditary disease among white children. The defective gene that causes CF affects glandular secretions by altering chloride transport across cell membranes. Thickening of bronchial secretions leads to infection and other respiratory disorders. Other mucus-secreting glands, sweat glands, and glands of the pancreas are also involved, causing electrolyte imbalance and digestive disturbances. Cystic Fibrosis

19. Chronic Obstructive Pulmonary Disease (COPD) Any of a group of chronic, progressive, and debilitating respiratory diseases, which includes emphysema, asthma, bronchitis, and bronchiectasis. Atelectasis Incomplete expansion of a lung or part of a lung; lung collapse. May be present at birth (as in respiratory distress syndrome) or be caused by bronchial obstruction or compression of lung tissue (prefix atel/omeans “imperfect”) Other Respiratory Diseases

20. Emphysema A chronic pulmonary disease characterized by enlargement and destruction of the alveoli • Acidosis Abnormal acidity of body fluids. Respiratory acidosis is caused by abnormally high levels of carbon dioxide in the body. • Alkalosis Abnormal alkalinity of body fluids. Respiratory alkalosis is caused by abnormally low levels of carbon dioxide in the body.

21. Mr C is 56 years of age and has a long history of chronic obstructive pulmonary disease (COPD). He began smoking at the age of 14 and until 6 years ago smoked approximately 25-30 cigarettes per day but now only smokes 2 or 3 per week. Five years ago he developed a squamous cell carcinoma and had a right upper lobectomy. Chronic Obstructive Pulmonary Disease

22. Mr C has had two acute exacerbations of bronchitis in the past year. His wife says that over the last few days he has become increasingly out of breath and has difficulty in walking, speaking and eating. He was seen in casualty with increasing dyspnoea , cyanosisand a productive purulent sputum.

23. On examination he had a degree of bronchospasmand was showing signs of hypoxia and hypercapnia. • His serious condition required his immediate transfer to the intensive therapy unit (ITU) for mechanical ventilatory support. • An arterial catheter for blood gas sampling was inserted via the left radial artery, and he was asleep. • He was given a muscle relaxant intravenously to enable tracheal intubation and commencement of intermittent positive pressure ventilation (IPPV).

24. acute symptoms/signs of short duration • carcinoma malignant growth from epidermal cells/a cancer • catheter a tube inserted into the body • chronic lasting/lingering for a long time • exacerbations acute increased severity of symptoms • intravenous pertaining to within a vein • intubation insertion of a tube into a hollow organ in this case the trachea • productive producing e.g. producing mucus/sputum • purulent resembling pus/infected • sedated state of reduced activity usually as a result of medication • sputum material expelled from the respiratory passages by coughing or clearing the throat • squamous pertaining to scale-like/from squamous epithelium Word Help
