Describe the Process of Respiration in Fish

Glycolysis The molecules of glucose get converted into pyruvic acid which is oxidized to carbon dioxide and water leaving two carbon molecules known as acetyl-CoA. For respiration the fishes like other vertebrates have ability to obtain oxygen from the external environment by means of vascularized gills lungs or skin and then transport to tissue through haemoglobin a conjugated protein present in RBC in the blood.

Respiratory System

3 During respiration water enters the body through mouth passes through gills and comes out of the operculum.

. A frog may also breathe much like a human by taking air in through their nostrils and down into their lungs. Suggest one advantage to a fish of this one-way flow of water over its gills. During respiration the floor of the buccal cavity is lowered and the mouth is opened.

External cutaneous respiration is the ancestral form of respiration found in most protochordates. The gills are covered by gill covers. Fishes respire through GILLS.

5 When water passes over the gills the gills extract dissolved oxygen from this waterThe extracted oxygen is absorbed by the blood and carried to all the parts of the fish for respiration release of energy. Less energy needed continuous flow of water or O2. Gills are present on either side of the head and are supplied by rich blood vessels.

The air from the nasal cavity passes to the pharynx which leads to the trachea through a slit called glottis. Water taken in continuously through the. Bony fish possess thousands of gills filaments that cover the operculum.

Oxygen and carbon dioxide dissolve in water and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills. Respiration in fishes Fish are the aquatic vertebrates which respire through structures called as gills. When water passes over the gills the dissolved oxygen is extracted.

The fish breathes by taking in water through its mouth and sending it over the gills. Air is drawn into the body through the nostrils. During external respiration gas exchange occurs at the level of the skin and oxygen and carbon dioxide are passed into and out of tissues.

The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels which give gills a bright red colour. Identify where each reactant or product is made or used in both processes. During the process of glycolysis two molecules of ATP and NADH are produced.

4 Exchange of gases takes place in the gills of fish supplied by numerous blood vessels. Discuss the relationship in terms of the reactants and products of each process using the appropriate terminology and level of detail ie. The fish breathes by taking in water through its mouth and sending it over the gills.

The fish breathes by taking in water through its mouth and sending it over the gills. The fish lives in water which contains dissolved oxygen. The extracted oxygen is absorbed by the blood and carried to all the parts of the fish.

The gills are covered by gill covers. They breathe by taking in water through their mouth and sending it over the gills. Respiration in bony occurs as the fish swims in water.

There is a one-way flow of water over the gills of a fish whereas there is a two-way flow of air in the lungs of a mammal. Describe how the process of respiration in the lamprey larva differs from that seen in lancelets the lamprey use muscular contraction in pharynx to pump food while lancelets use cilia motion what features of the lampreys head represent homologies to other vertebrate groups. Respiration is a process of taking in oxygen and removing out carbon-di-oxide to produce energy from the oxidation of complex organic substances.

There are usually 4 to 7 pairs of Gills present in most fish species. Describe how cellular respiration and photosynthesis interact in a fish tank containing aquatic plants and small aquatic organisms. Then the water rushes in to fill the greatly expanded buccal cavity.

The process of respiration involves intake of oxygenated air into the cells for breaking the food and releasing energy. Branchiae is the Greek word for Gills. Water flowing over fish gills exchanges gases with blood flowing in.

The extracted oxygen is absorbed by the blood and carried to all the parts of the fish. Fishes respire through Gills. Fish obtain oxygen dissolved in water.

Describe the ventilation mechanism in fish The buccal cavity of the fish opens and the buccal floor moves downwards. The fish lives in water which contains dissolved oxygen. The extracted oxygen is absorbed by the blood and carried to all the parts of the body.

The water then goes out through the gill slits. The three phases of Respiration are. Gills are present on both the sides of the head of fish.

UDOLSTES16385 - Describe the process of respiration in invertebrates living on land. When water passes over the gills the gills extract dissolved oxygen from the water. This is called as branchial respiration.

2 Fish obtain oxygen dissolved in water. This creates a larger volume in the buccal cavity causing pressure to fall relative to the pressure in the external environment. For breathing the fish use the oxygen dissolved in water.

When water passes over the gills the gills extract dissolved oxygen from the water. The process still occurs in small vertebrates as long as they have low activity levels and live in. However water flows over.

Rapid growth of algae and phytoplankton Rate of decomposer respiration increases as additional dead algae sink to lake bottom Fish die of suffocation o in water becomes depleted Nutrients released into water from fertilizer run-off for example Do you know the answer. Fish- fish respiration takes place through special respiratory organs called gills however lung fish respiration takes place through lungs. 1 Gills are present on either side of the head and are supplied by rich blood vessels.

The mouth is now closed and the pharynx contracts. The water then enters the gill-pouches and goes out after gaseous exchange through gill-slits.
