Aquatic respiration. Sea slugs respire through a gill (or ctenidium) Aquatic respiration is the process whereby an aquatic organism exchanges respiratory gases with water, obtaining oxygen from oxygen dissolved in water and excreting carbon dioxide and some other metabolic waste products into the water.
Fish physiology is the scientific study of how the component parts of fish function together in the living fish. [ 2 ] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or ...
Fish gill. Gill arches bearing gills in a pike. Gills allow fish to breathe underwater. Respiratory mechanism in bony fish. The fish draws oxygen-rich water in through the mouth (left). It then pumps it over gills so oxygen enters the bloodstream, and allows oxygen-depleted water to exit through the gill slits (right) Fish gills are organs that ...
Respiratory system. The respiratory system (also respiratory apparatus, ventilatory system) is a biological system which consists of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives ...
Spiracle (vertebrates) Spiracles (/ ˈspɪrəkəl, ˈspaɪ -/ [1][2]) are openings on the surface of some animals, which usually lead to respiratory systems. The spiracle is a small hole behind each eye that opens to the mouth in some fish. In the jawless fish, the first gill opening immediately behind the mouth is essentially similar to the ...
Lungfish have a highly specialized respiratory system. They have a distinct feature in that their lungs are connected to the larynx and pharynx without a trachea. While other species of fish can breathe air using modified, vascularized gas bladders, [6] these bladders are
The lungs are the main organs of the respiratory system in most terrestrial animals, including all tetrapod vertebrates and a small number of amphibious fish (lungfish and bichirs), pulmonate gastropods (land snails and slugs, which have analogous pallial lungs), and some arachnids (tetrapulmonates such as spiders and scorpions, which have book ...
The Anabantoidei are a suborder of anabantiform ray-finned freshwater fish distinguished by their possession of a lung -like labyrinth organ, which enables them to breathe air. The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies (which more precisely refers to the family Osphronemidae).
