  «Respiratory system»
  

• 2 слайд

  The human respiratory system is a set of organs and tissues that ensure the exchange of gases between the blood and the external environment in the human body.
  

• 3 слайд

  The cells of the human body require a constant stream of oxygen to stay alive. The respiratory system provides oxygen to the body’s cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate.
  

• 4 слайд

  There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.
  

• 5 слайд

  The lungs act as the functional units of the respiratory system by passing oxygen into the body and carbon dioxide out of the body.
  

• 6 слайд

  The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.
  

• 7 слайд

  Finally, the muscles of respiration, including the diaphragm and intercostal muscles, work together to act as a pump, pushing air into and out of the lungs during breathing.
  

• 8 слайд

  The pleura is a thin, smooth and moist, serous membrane rich in elastic fibers that covers each of the lungs.
  

• 9 слайд

  Respiratory system function:
  oxygen entering the body;
  removal of carbon dioxide from the body;
  removal of gaseous metabolic products from the body;
  thermoregulation;
  synthetic: some biologically active substances are synthesized in lung tissue: heparin, lipids, etc.;
  hematopoietic: mast cells and basophils mature in the lungs;
