What else can I help you with?
Would gills function well to remove oxygen from the water if they had few blood vessels?
No
How do goldfish gills function to extract oxygen from water for respiration?
Goldfish gills have thin, feathery structures called filaments that are covered in tiny blood vessels. As water passes over the gills, oxygen from the water diffuses into the blood vessels and carbon dioxide from the fish's blood diffuses out into the water. This process allows the goldfish to extract oxygen from the water for respiration.
Why would you expect gills to have an exceptionally large number of capillaries?
Capillaries, which are the smallest of the blood vessels, are the site of gas exchange...carbon dioxide diffuses out of surrounding cells into the gills to be lost into the environment, and oxygen diffuses from the environment into the gill cells and then surrounding tissues. The gills function like the lungs of a fish, so large numbers of capillaries in these structures function to supply oxygen/get rid of waste carbon dioxide for the organism.
Why fish are red?
The gills are sided by a series of capillaries. Capillaries are small blood vessels. These capillaries are used to transport oxygen from the gills throughout the fish.
What is the function of the gills on a squid?
The octopus passes blood to its gills where it dumps co2 and takes rich oxygen
Why do fish gills contains lots of blood vessels?
Fish gills are the equivalent of human lungs. Our lungs, and the fish's gills, are the part of the body that absorb the oxygen we need and expel the carbon dioxide that we nave to get rid of. The way that this happens is through the blood vessels (arteries carry oxygen-rich blood around the body, while veins carry deoxygenated blood) Humans extract oxygen from the air that they breathe into their lungs, while fish obtain their oxygen from the water that passes through their gills.
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.
Why do fish need gills?
Fish need gills to extract oxygen from water in order to breathe. Gills are specialized structures that contain blood vessels where gas exchange takes place, allowing fish to obtain the oxygen they need to survive. Without gills, fish would not be able to extract oxygen from water efficiently.
What structure in fish performs the same function as lungs in mammals?
GillsThe gills perform the same function.
Why are Fish able to breathe in water?
Because they Have Gills, and gills help them to breathe in the water. As water flows over the gills, a fine network of blood vessels can extract oxygen from the water, much like our lungs collect oxygen from the air when we breathe.
What is the function of the ostia in a crayfish?
It pumps newly oxygenated blood that's come from the gills into the heart, to circulate again.
How and where is oxygen is obtained in the gills?
Oxygen is obtained by diffusion from water flowing over the gill membranes, where it dissolves in the thin, moist epithelial layer of the gills. This exchange of oxygen and carbon dioxide occurs due to the difference in concentration gradients between the water and the blood vessels in the gills.
