Does fish has kidneys?
The same thing any animals' kidneys do. They filter out impurities from the blood so they can be excreted. More importantly in fish, the kidneys are a major organ to help maintain osmotic balance with their environment. In freshwater fish, they retain salts in the blood of the fish (since the fish is hyperosmotic to its environment, the salts want to diffuse out, and lots of water wants to move into the fish) while they are constantly urinating because of the net movement of water into the fish. In SW fish, the kidneys help move OUT extra salts taken in when the fish drinks seawater, because the salts want in and the water wants out (the fish is hypo osmotic to the seawater).
What Organ removes nitrogenous wastes from the blood of fish?
The malpighian tubules are the organs used to remove nitrogenous waste from a grasshopper. These tubules also regulate the internal ionic balance of the grasshopper.
Which fin helps a fish turn balance and brake?
Fish use all their fins in conjunction with one another to manouver in the water. They increase or decrease their depth (go up and down) in the water by inflating and deflating an organ called a "swim bladder".
What is a fish balance called?
The swim bladder is the organ that keeps the fish balanced and upright, is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy. It is also known as the gas bladder, fish maw or air bladder.
What is the water pressure organ in bony fish?
The sweg
Saltwater fish remove extra salt from their body by active transport through the gills what is the result of this activity?
water balance is maintained in the blood
Do fish live in and breathe water?
Yes. They live in water and would dehydrate and die out of water if they did not suffocate first. The fish use their gills to collect oxygen in the water and mix it with their blood in a very simple circuit system. Some types of fish known as labyrinth fish have a labyrinth organ that allows them to breathe air for short periods.
What is the organ of a fish that filters the blood?
Fish, like humans, have kidneys which regulate the water and salt content of the body. This process is often referred to as filtration, though in fact it is a combination of several complex processes.
What is the main function of the fins?
It is to balance the fish in the water.
What organ systems are interacting in the fish?
the water enters threw the gills oxygen from the water passes threw a thin membrane and into the blood stream carbon dioxide passes from the blood into the water in the gills so that means that the circulation system and the resportory system are working together
What is the organ of fish?
Human beings breathe using our lungs. Oxygen goes into our blood and carbon dioxide goes out of our blood and into our lungs. When we breathe out we get rid of it. These gasses dissolve in our blood. In water there is dissolved oxygen. Fish don't have lungs; they have specially developed organs called gills. As water flows over the gills oxygen is absorbed and carbon dioxide can come out of the fish's blood through the delicate membrane of the gills. Some fish are able to pump water over their gills, which means that they can lie on the bottom or stay still in the water. Other fish need to keep moving to pass fresh water over their gills.
