Chapter 17 Breathing and Exchange of Gases Class 11 NEET Biology deals with:

  •     The process of exchange of O2 from the atmosphere with CO2 produced by the cells is called breathing.
  •     Breathing is a physical process which is a part of respiration. It involves the exchange of gases between an organism and its external environment.
  •     Breathing is carried out with the help of special organs called the respiratory organs.
  •     Oxygen (O2) is utilised by the organisms to indirectly break down nutrient molecules like glucose, fatty acids and proteins and to derive energy for performing various activities.
  •     Carbon dioxide (CO2) is released during the above catabolic reactions.

Respiratory organs

  •     Lower invertebrates like sponges, exchange O2 with CO2 by simple diffusion over their entire body surface.
  •     Earthworms use their moist cuticle and insects have a network of tubes (tracheal tubes) to transport atmospheric air within the body.
  •     Special vascularised structures called gills are used by most of the aquatic arthropods and molluscs.
  •     Vascularised bags called lungs are used by the terrestrial forms for the exchange of gases.
  •     Amphibians, like frogs, can respire through their moist skin also.
  •     Mammals have a well-developed respiratory system.

Human respiratory system

  •     A pair of external nostrils opens out above the upper lips, which leads to a nasal chamber through the nasal passage, and the nasal chamber opens into nasopharynx, which is a portion of pharynx.
  •     Nasopharynx opens through glottis of the larynx region into the trachea.
  •     Larynx is a cartilaginous box which helps in sound production and hence called the sound box.
  •     During swallowing, glottis can be covered by a thin elastic cartilaginous flap called epiglottis.
  •     Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the level of 5th thoracic vertebra into a right and left primary bronchi.
  •     Each bronchus undergoes repeated divisions to form the secondary and tertiary bronchi and bronchioles ending up in very thin terminal bronchioles.
  •     The tracheae, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings.
  •     Each terminal bronchiole gives rise to a number of very thin, irregular walled and vascularised bag-like structures called alveoli.
  •     The branching network of bronchi, bronchioles and alveoli comprise the lungs.
  •     Two lungs are covered by a double layered pleura, with pleural fluid between them.
  •     The outer pleural membrane (called the parietal pleura) is in close contact with the thoracic lining, whereas the inner pleural membrane (called the visceral pleura) is in contact with the lung surface.
  •     The external nostrils up to the terminal bronchioles constitute the conducting part, whereas the alveoli and their ducts form the respiratory part.
  •     The conducting part transports the atmospheric air to the alveoli, clears it from foreign particles, whereas exchange part is the site of actual diffusion of O2 and CO2 between blood and atmospheric air.
  •     The lungs are situated in the thoracic chamber, formed dorsally by the vertebral column, ventrally by the sternum, laterally by the ribs and on the lower side by the dome-shaped diaphragm.
  •     Respiration involves the following steps:
  •     Breathing or pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out.
  •     Diffusion of gases (Oand CO2) across alveolar membrane.
  •     Transport of gases by the blood.
  •     Diffusion of O2 and CO2 between blood and tissues.
  •     Utilisation of O2 by the cells for catabolic reactions and resultant release of CO2.
