because in many organisms like fish etc it is an organ for respiration the gills are supplied with capillaries so that the oxygen absorbed can diffuse into the blood it has large surface area so that more oxygen can be diffused in and more co2 can be removed

How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
Why do leaves have a large surface area?
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
What are the characteristics of respiratory surface?
large area
What organelle has a large amount of surface area?
The Alveoli
Why is a catalyst spread over a large surface area?
So it is more efficient.
Why is it important that the gills of a crayfish give them a large surface area?
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê
Why do the gills have a large surface area and rich in blood vessels?
Gills are the underwater equivalent of our lungs and they need those features in order to extract enough oxygen from the water so that they can breath.
Which feature is common to gills lungs and tracheae?
Large surface area
Why is the feathery nature of gills gives them a very large surface area is important?
Without the large surface are, the gills would have to be much larger and that may have prevented the development of the organisms that use gills.
How does the structure of gills allow for the production of so many spore?
large surface area.
The feathery nature of the gills gives the crayfish a very large surface area why is this important?
The large surface area of the gills in crayfish allows for efficient absorption of oxygen from water and release of carbon dioxide. This is important for the crayfish as it helps them to breathe and obtain the necessary oxygen for cellular respiration.
How is respetory gas exchange maximised in fish gills?
Gills are composed of thousands of filaments which are covered in lamellae (only a few cells thick and contain blood capillaries). This creates a large surface area and a short distance for gas exchange.
How do gills extract oxygen from H2o?
Whale shark gills are similar in structure to other fish gills. Oxygenated water is passed over the gills which have a rich, near surface blood supply and gases are exchanged between the blood and the water. The gills are feathery and have a large surface area so that there is enough gas exchange to keep the fish supplied with the oxygen it needs.
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
What do aquatic arthropods exchange gases through?
Aquatic arthropods typically exchange gases through gills. Gills are structures that are rich in blood vessels and provide a large surface area for gas exchange to occur, allowing the arthropods to extract oxygen from the water and release carbon dioxide.
How does the structure of mushroom gills allow for the production of so many spores?
The gill provide a very large surface area for the space that they have.
Why does a red blood cell have a large surface area?
To hold more oxygen.
