If there is a good blood supply to the gills of a fish it will be breathing and acting normally.
As all fish are quite different this will have to be compared to an average happily living fish of the same br
The red color of gills is from hemoglobin. Also, think about the size of the gills relative to the overall size that different fish can achieve it also stands to reason that
sufficient oxygen must be transported to all the tissues via blood...as well as any expiration gases hence the gills have massive amounts of blood.
Fish need a rich blood supply in the gills because they have a pretty much closed circuit wiring system. Through the gills is where the water carries the minuscule amounts of oxygen to be absorbed in the gills and delivered into the blood stream which then carries the newly oxygenated blood through out the body to be used up.
The gills is where the fish extract oxygen from the water for the blood supply and also where it expels carbon dioxide. The gills are the start and the end.
To oxygenate the blood
production of red blood cells and immune response
A perch could be on a perch after some sort of storm that would cause the perch to be blown from the water and into a tree or a telephone pole.
10 square perch is 0.0625 acre.
Perch have complete digestive systems
To oxygenate the blood
perch have gills and is consider to be in the fish family.
No, they have gills to extract oxygen from water. and since they do that i do believe that they stay on the bottom or reef of the ocean or wherever they live!
Gills
The operculum
There are three species of the perch: Percaflavescens (Yellow perch), Perca fluviatilis(European perch) and Perca schrenkii (Balkhash perch).
There are two gills located on each side of a perch. The Opercula is the covering that protect the gills.
The Perch, like all gilled fish, has a two-chambered heart consisting of a single Atrium and ventricle. De-oxygenated blood is pumped through the heart into the gills, where it becomes oxygenated and then flows to the perch's body tissue through arteries. Atrium-->Ventricle-->gills-->arteries-->body tissue-->veins-->repeat
Behind the flap of skin that covers them, it is also above the heart.
It helps the gills facilitate osmotic pressures via ducts and membranous sacs
A few adaptations of perch (really all fish) are the eyes, scales, fins, gills, mucous, etc. (There are a lot!) Eyes- see, Scales- protect from environment, Fins- help fish swim, Gills- breath underwater, Mucous- escape predators fast...
The gills of a fish are lined with many red, blood-rich capillaries called filaments. As water passes over the gills, oxygen is absorbed out of the water through the filaments into the bloodstream.
