Cystic fibrosis is an inherited disease of the secretory glands that causes persistent lung infections and limits the ability to breathe over time. It causes cells to produce thick and sticky mucus‚ sweat‚ and digestive juices that block airways‚ ducts‚ and passageways. There is no cure‚ but there are ways to manage symptoms. According to the World Health Organization‚ the occurrence of cystic fibrosis varies across

so the more they will smoke. This means that they will be inhaling more toxic substances into their body‚ particularly the lungs‚ and this affects the breathing system as these substances will damage the lungs and cause a reduction in their ability to function properly. Carbon Monoxide One of the main functions of the respiratory system is to provide the body with oxygen so that it can be delivered to vital cells that require oxygen to function. Oxygen is carried in red blood cells by reaction with

40) Describe the structure of a mammalian respiratory system. Include in your discussion the mechanisms of inspiration and expiration. In mammals‚ oxygen first passes through the nasal cavity. The nasal cavity is covered with mucus and cicilia to filter the air. The nasal cavity leads to the pharynx. The pharynx consists of the eustachian tube and the tonsils. The inhaled air then passes to the larynx‚ trachea‚ and bronchi. The bronchi lead to the bronchioles in the lungs. In the lungs the pleural

This experiment was administrated to help us understand better the role of surfactant in the alveolar system. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the alveoli. Surfactant is produced to make it easier for people to breath by reducing the surface
