For example, bluefin tuna maintain a core body temperature of 25–33 °C (77–91 °F), in water as cold as 6 °C (43 °F). However, ... certain areas of their body. Additionally, this increase in temperature leads to an increase in basal metabolic temperature. The fish is now able to split ATP at a higher rate and ultimately can … See more Fish physiology is the scientific study of how the component parts of fish function together in the living fish. It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish … See more Jaws allow fish to eat a wide variety of food, including plants and other organisms.

Gills are tissues which consist of threadlike structures called See more The circulatory systems of all vertebrates are closed, just as in humans. Still, the systems of fish, amphibians, reptiles, and birds show various stages of the evolution of the circulatory system. In fish, the system has only one circuit, with the blood being pumped through … See more Two major types of osmoregulation are osmoconformers and osmoregulators. Osmoconformers match their body osmolarity to their … See more WebMost fishes exchange dissolved oxygen and carbon dioxide in water using gills which lie behind and to the side of the mouth cavity. The circulatory system consists of the heart, arteries, capillaries, and veins. The heart pumps the blood to the gills to be re-oxygenated. From there, blood is distributed to the tissues and organs of the body.
