Respiration organs (or breathing organs) are used by most, or all, animals to exchange the gases necessary for their life function known as respiration
Respiration (physiology)

In animal physiology, respiration is the transport of Oxygen from the outside air to the cells within Tissue s and the transport of carbon dioxide in the opposite direction....
. These organs come in many forms, some of them apparently having independently evolved:

  • skin
    Skin

    The skin is the outer covering of the body, also known as the epidermis. It is the largest organ of the integumentary system made up of multiple layers of epithelial biological tissue, and guards the underlying muscles, bones, ligaments and organ s....

    Spider

    Spiders are air-breathing chelicerate arthropods that have eight legs, and chelicerae modified into fangs that inject venom. In their bodies the usual arthropod segments are fused into two Tagma , the cephalothorax and abdomen, joined by a small, cylindrical pedicel....

    Mite

    Mites, along with ticks, belong to the subclass Acarina and the class Arachnida. Mites are among the most diverse and successful of all the invertebrate groups....
    s, for example), animals can breathe simply by exchanging gas through the surface of their body
  • gill
    Gill

    A gill is an anatomical structure found in many aquatic ecosystem organisms. It is a respiration organ whose function is the extraction of oxygen from water and the excretion of carbon dioxide....
     – many aquatic, and a few smaller terrestrial, animals use gills to breathe. Even land animals can do this, as with isopods like the woodlice
    Woodlouse

    Woodlice are crustaceans with a rigid, segmented, long exoskeleton and fourteen jointed limbs. They form the suborder Oniscidea within the order Isopoda, with over 3,000 known species....
     that probably can be found living under rocks in a yard. Gills are simply layers of tissue adapted specifically to gas exchange.
  • book lung
    Book lung

    A book lung is a type of respiration organ used for atmospheric gas exchange and is found in arachnids, such as scorpions and spiders. Each of these organs is found inside a ventral abdominal cavity and connects with the surroundings through a small opening....
     – Some spiders, scorpion
    Scorpion

    Scorpions are any arachnid of the order Scorpionida. They are members of the order Scorpiones within the class Arachnida. There are about 2,000 species of scorpions, found widely distributed south of about Latitude, except New Zealand and Antarctica....

    Arthropod

    Arthropods are animals belonging to the Scientific classification Arthropoda , and include the insects, arachnids, crustaceans, and others....
    s still use primitive book lungs, essentially gills adapted for land use, in their respiration. These are simply tissue with many wrinkles to increase their surface area.
  • Labyrinth organ – A secondary breathing organ specific to the labyrinth fish, essentially an enclosed maze of tissue, evolved from a niche in their gill structure.
  • Invertebrate trachea
    Invertebrate trachea

    Many terrestrial animal arthropods have evolved a closed respiratory system composed of spiracles, tracheae, and tracheoles to transport metabolism gasses to and from tissue....
     – tubes evolved by many arthropods, possibly from book lungs, which simply lead directly into their bodies through holes called spiracle
    Spiracle

    Spiracles are small openings on the surface of some animals that usually lead to respiratory systems.In elasmobranchs , a spiracle is found behind each eye, and is often used to pump water through the gills while the animal is at rest ....
    s, where their internal organs generally absorb their own air. These can be very primitive, as with some spiders, or more complex, ending with specialized air sacs, as with many insects.
  • lung
    Lung

    The lung is the essential respiration organ in air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located in the chest on either side of the heart....
     – The lung is made up of muscle tissues, the cells inside the lung which collect the oxygen in the air and pass it into the blood stream via veins and carbon dioxide passes out and that is breathing respiratory
    Respiratory system

    A respiratory system?s function is to allow gas exchange. The space between the alveoli and the capillaries, the anatomy or structure of the exchange system, and the precise physiological uses of the exchanged gases vary depending on the organism....
