Information about Respiration Organ

Breathing / Respiration organs are used by most, or all, animals to exchange the gasses necessary for their life functions, known as respiration. These organs come in many forms, some of them apparently having independently evolved:
  • skin -- some aquatic, or small terrestrial (some of the smallest spiders and mites, for example), animals can respirate simply by exchanging gas through the surface of their body
  • gill -- many aquatic, and a few smaller terrestrial, animals use gills to breath. Yes, even land animals can do this, as with isopods like the woodlice you probably can find living under rocks in your yard. Gills are simply layers of tissue adapted specifically to gas exchange.
  • book lung -- Some spiders, scorpions, and other arthropods 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 -- tubes evolved by many arthropods, possibly from book lungs, which simply lead directly into their bodies through holes called spiracles, 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 -- The lung is made up of muscle tissues the cells inside the lung which collect the oxygen in the air pass it into the blood stream via vein and carbon dioxide passes out and that is breathing respiratory.
In animal physiology, respiration is the transport of oxygen from the ambient air to the tissue cells and the transport of carbon dioxide in the opposite direction. This is in contrast to the biochemical definition of respiration, which refers to cellular respiration

A gill is a respiration organ that functions for the extraction of oxygen from water and the excretion of carbon dioxide. Unlike many small aquatic animals, which can absorb oxygen through the entire surface of their bodies, more complex aquatic organisms have gills specially

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.

Spiracles are small openings on the surface of some animals that usually lead to respiratory systems.

In elasmobranchs (sharks and rays), a spiracle is found behind each eye, and is often used to pump water through the gills while the animal is at rest (Fouts, 2003).

lungs flank the heart and great vessels in the chest cavity.[1]]]

The lung is the essential respiration organ in air-breathing vertebrates, the most primitive being the lungfish.

respiratory system generally includes tubes, such as the bronchi, used to carry air to the lungs, where gas exchange takes place. A diaphragm pulls air in and pushes it out. Respiratory systems of various types are found in a wide variety of organisms.
