Respiratory SystemBy: eduardo, jesus, stephanieStructure and function
  • Respiratory system consists of the lungs and air passages
  • System responsible for taking in oxygen (gas needed by all body cells and removing carbon dioxide
  • Body has 4-6 minutes to supply oxygen so the respiratory system must be continuously working to prevent death.
  • Nose
  • Two openings called the nostrils through which air enters. A wall of cartilage (nasal septum) divides the nose into hollow spaces called nasal cavities.
  • Nasal cavities are lined with mucous membrane.
  • Mucus produced by mucous membranes moistens the air and helps trap pathogens and dirt
  • Pharynx Lies directly behind the nasal cavities Air leaves nose and enters pharynxDivided into 3 sections Nasopharynx is the upper portion located behind the nasal cavities Oropharynx is the middle section behind the oral cavity (mouth)Laryngopharynx bottom section. Esophagus carries air to and from lungs off laryngopharynxLarynx
  • Voice box. Lies between the pharynx and trachea
  • 9 layers of cartilage
  • The largest (thyroid cartilage) called Adams apple.
  • Two folds called the vocal cords
  • Air leaves lungs, vocal cords vibrate and produce sound.
  • Epiglottis closes opening into larynx during swallowing
  • Trachea
  • Trachea carries air between Larynx and bronchi
  • Center of the chest
  • Trachea divides into two bronchi near center of the chest. Right bronchus and left bronchus
  • Bronchi Each bronchus enters a lung and carries air from trachea to lungIn the lungs the bronchi continue to divide into smaller and smaller bronchi until divided into the smallest branches bronchioles Smallest bronchioles called terminal bronchioles end in air sacs called alveoli Alveoli Resembles a bunch of grapesAdult lung contains 500 million alveoli Contain rich network of blood capillariesAllow carbon dioxide to be exchanged between the blood and lungs Inner surfaces of lipid substance called surfactant to help prevent from collapsing Lungs Right lung has 3 sections; the superior, the middle, the inferior Left lung has 2 lobes; superior and inferior Left lung is smaller because the heart is located towards the left side of the chestEach lung enclosed by a membrane called pleuraThe pleuraConsists of two layers: a visceral attached to the surface of the lung, and a parietal pleura attached to the chest wallPleural space located between the two layers is filled with a thin layer of pleural fluid that lubricates the membranes and prevents friction of lungs during breathing Both of the lungs, heart and major blood vessels are located in the thoracic cavity External respiration The exchange of oxygen, and carbon dioxide between the lungs, and the bloodstream. Oxygen, breathed through the Respiratory System, enters the alveoli.Oxygen concentration in the alveoli is higher than oxygen concentration in blood capillaries, Oxygen leaves the alveoli and enters the capillaries, and bloodstream.Carbon dioxide concentration in the capillaries is higher than the carbon dioxide concentration in the alveoli, carbon dioxide leaves the capillaries and enters the alveoli.Internal respirationExchange of carbon dioxide and oxygen between the tissue cells and the bloodstream.Oxygen is carried to the tissue cells by the blood. Oxygen concentration in the blood is higher than oxygen concentration in tissue cells, Oxygen leaves the blood and, enters the tissue cells.Carbon dioxide concentration in the tissue cells is higher than carbon dioxide concentration in bloodstream, carbon dioxide leaves the tissue cells and enters the bloodstream.Cellular respirationCells use the oxygen and nutrients to produce energy , water, and carbon dioxide.DiseasesAsthmaAsthma is a disorder that causes the airways of the lungs to swell and narrow, leading to shortness of breath, chest tightness, and coughing. Caused by a sensitivity to an allergen such as dust, pollen, an animal fur, or food.Can also be caused by stress, and overexertion.BronchitisAn inflammation of the branch and the bronchial tubes.It is usually caused by infection, and is characterized by a productive cough, dyspnea , chest pain, and fever.EmphysemaNoninfectious, chronic respiratory conditionOccurs when the walls of the alveoli deteriorate and lose their elasticity.Epistaxis (Nosebleed)Capillaries in the nose become congested and bleed.It can be caused by an injury or blow to the nurse.PneumoniaAn inflammation or infection of the lungs characterized by exudate in the alveoli.Caused by bacteria, viruses, or chemicals.ProfessionsInternistInternal medicineYuri O.
