Adaptations to Aquatic Habitats - British Ecological Society
WebIn this video, we look at the tracheal system in insects. This is a nice quick and short topic, but can be tricky!- The overall structure of the system- Vent... Some aquatic insects, such as rat-tailed maggots, maintain a connection with air on the surface through a snorkel-like structure. A few insects have modified spiracles that can pierce the submerged portions of aquatic plants, and take oxygen from air channels within their roots or stems. See more For insects, air enters the respiratory systems through a series of external openings called spiracles. These spiracles, which act as muscular valves in some insects, lead to the … See more Insects can control respiration to some degree. They are able to open and close their spiracles via muscle contractions. For example, an … See more Many water-dwelling insects have tracheal gills, which are layered extensions of their bodies that enable them to take in greater quantities of oxygen from water. These gills are most often located on the abdomen, but in some … See more While oxygen is plentiful in the air (200,000 parts per million), it is considerably less accessible in water (15 parts per million in cool, flowing water).

Getting Oxygen - British Ecological Society
WebOrganisms that live in water need to obtain oxygen from the water. Oxygen dissolves in water but at a lower concentration than in the atmosphere. The atmosphere has roughly 21 percent oxygen. In water, the oxygen concentration is much smaller than that. ... Insects perform respiration via a tracheal system. Mammalian Systems. WebIn insects, the tracheal tubes primarily deliver oxygendirectly into the insects' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles … fishy fishy lunch menu
