What is the difference between a crayfish circulatory system and a humans circulatory system?
A crayfish has an open circulatory system while humans have a closed circulatory system. "Closed" means that we have true blood vessels that carry blood to and from the heart. "Open" means that the organs are simply bathed in blood that freely circulates around the body. Sometimes the heart can move the "blood" by creating pressure waves in the fluid.
Do arthropods have a open circulatory system?
Yes, most arthropods have an open circulatory system, which means that their blood, called hemolymph, directly bathes their tissues. This system is less efficient at transporting oxygen compared to closed circulatory systems found in vertebrates.
What would have happened if humans had not developed a circulatory system?
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Compare the circulatory system of each of the three major classes of mollusks?
In cephalopods like octopuses, the circulatory system is closed, with blood contained in vessels. Bivalves like clams have an open circulatory system where blood is pumped into a hemocoel. Gastropods, such as snails, have a mix of closed and open circulatory systems, with a heart that pumps blood through vessels but also into spaces around organs.
Are crayfish herbivore?
Crayfish are omnivores, meaning they are both an herbivore and a carnivore.
How do the respiratory structures differ for crayfish and grasshoppers?
In crayfish, gills are required to perform respiration whereas grasshoppers get oxygen for respiration straight from the atmosphere.
What are examples of animals with an open circulatory system?
grasshoppers, have an open circulatory system
How are grasshoppers and crayfish similar?
These creatures are a like because they both have antennas. They are different because grasshoppers breath through little spirals, but crayfish breathe normaly.antenna, madible, walking legs
What kind of circulatory system does a grasshopper have?
Grasshoppers have an open circulatory system which might answer this question.
Does a crayfish have a open or closed circulatory system?
Crayfish, along with all other arthropods, have an open circulatory system. There are no veins and no separation of blood from interstitial fluid.
Crayfish what body system does the antenna belong to?
Circulatory ?
Does a crayfish have an open circulatory system?
Crayfish, along with all other arthropods, have an open circulatory system. There are no veins and no separation of blood from interstitial fluid.
What structures do spiders grasshoppers and crayfish have for exchanging gases?
spiders: book lung grasshopper : trachea crayfish: gills
What is a major difference between the circulatory of a grasshopper and that of an earthworm?
Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)
Do grasshoppers have an open circulatory system?
Yes, grasshoppers have an open circulatory system. This means that their blood is not enclosed within vessels and instead bathes their internal organs directly. The blood, called hemolymph, circulates through the body cavity.
What are the similarities and differences between ants and crickets?
Grasshoppers have spiracles that help them breath whereas crayfish breath through gills.
What is the difference between a crayfish circulatory system and a humans circulatory system?
A crayfish has an open circulatory system while humans have a closed circulatory system. "Closed" means that we have true blood vessels that carry blood to and from the heart.
