Smoking affects breathing system‚ facts and diseases. The major health problems caused by smoking affect the nicotine delivery system: the airways‚ blood vessels and lungs in the human respiratory system. During normal breathing‚ air is ingested through the nose or mouth and travels through the bronchial tubes to the lungs. There‚ the oxygen collects in the alveoli‚ or air sacs‚ and diffuses into the bloodstream‚ to be pumped by the heart to the brain and body. Cigarette smoking upsets this balanced

corresponds with lungs via pleurae; parietal pleura adheres to the thoracic wall and superior diaphragm and visceral - clings to the lungs. Normally the pleurae can glide against each other but resist separation because of surface tension created by the lubricant - pleural fluid. Therefore when healthy thoracic cavity expands‚ the lungs are stretched out and opened up and when healthy thoracic cavity decreases in size lungs spontaneously recoil. The opposite forces created by inward pull of lungs (naturally

injury to the lung which is a common result after a blunt chest trauma from incidents such as vehicular accidents and assaults or after penetrating chest trauma from explosions or shock waves (Ganie et al‚ 2013). Also‚ although it is more commonly associated with chest traumas such as pneumothorax‚ rib fractures or hemothorax‚ pulmonary contusion is also related to trauma to the abdomen and nervous system (Sutyak et al‚ 2007). After a blunt force trauma occurs‚ lacerations develop in the lung parenchyma

Edge of the medial border of scapula is at the midline of lung field in AP. * Inspiration: Count the visible ribs. Lung fields should extend to about the 10th or 11th rib. * Exposure: If the film is penetrated enough‚ you should be able to make out the spinous processes "inside" the vertebrae.

Red blood cell contains haemoglobin that transports oxygen molecules from the lungs to other parts of the body. On the other hand‚ haemoglobin has higher affinity to carbon monoxide as compared to oxygen. This shows that less oxygen reaches the brain‚ muscles‚ heart and other organs Hydrogen cyanide The lungs have tiny hair that help in

In some patients that has COPD it cause by tobacco smoke‚ later in life patients considered by moderately reversible airflow limitation that result to lung function and can lead to premature death. These two diseases are described by the physiological and anatomic extremes of COPD and asthma that
