How does the insect breathe?
A butterfly respires. They use oxygen to survive the same way other animals do, as energy. Since insects including butterflies don't have lungs, it sucks air into specialized air organs and releases carbon dioxide.
How is the circulatory system of insects different from mammals?
Yes, in fact you can see veins on the wings of some flying bugs, such as dragonflies. I also found out that spiders don't have muscles; their blood circulates very swiftly from one leg to the other for them to run.
Insects belongs to the group of?
insects belong to the group arthropods.An arthropod is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages. Arthropods form the phylum Arthropoda, and include the insects, arachnids, myriapods, and crustaceans. Arthropods are characterized by their jointed limbs and cuticle made of α-chitin and/or calcium carbonate.The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Their versatility has enabled them to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80% of all described living animal species, some of which, unlike most animals, are very successful in dry environments. They range in size from microscopic plankton up to forms a few meters long. Arthropods' primary internal cavity is a hemocoel, which accommodates their internal organs, and through which their haemolymph - analogue of blood - circulates; they have open circulatory systems. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-like", with paired ventral nerve cords running through all segments and forming paired ganglia in each segment. Their heads are formed by fusion of varying numbers of segments, and their brains are formed by fusion of the ganglia of these segments and encircle the esophagus. The respiratory and excretory systems of arthropods vary, depending as much on their environment as on the subphylum to which they belong.Their vision relies on various combinations of compound eyes and pigment-pit ocelli: in most species the ocelli can only detect the direction from which light is coming, and the compound eyes are the main source of information, but the main eyes of spiders are ocelli that can form images and, in a few cases, can swivel to track prey. Arthropods also have a wide range of chemical and mechanical sensors, mostly based on modifications of the many setae (bristles) that project through their cuticles. Arthropods' methods of reproduction and development are diverse; all terrestrial species use internal fertilization, but this is often by indirect transfer of the sperm via an appendage or the ground, rather than by direct injection. Aquatic species use either internal or external fertilization. Almost all arthropods lay eggs, but scorpions give birth to live young after the eggs have hatched inside the mother. Arthropod hatchlings vary from miniature adults to grubs and caterpillars that lack jointed limbs and eventually undergo a total metamorphosis to produce the adult form. The level of maternal care for hatchlings varies from nonexistent to the prolonged care provided by scorpions.The evolutionary ancestry of arthropods dates back to the Cambrian period. The group is generally regarded as monophyletic, and many analyses support the placement of arthropods with cycloneuralians (or their constituent clades) in a superphylum Ecdysozoa. Overall however, the basal relationships of Metazoa are not yet well resolved. Likewise, the relationships between various arthropod groups are still actively debated.Arthropods contribute to the human food supply both directly as food, and more importantly as pollinators of crops. Some specific species are known to spread severe disease to humans, livestock, and crops.
The major body space in arthropods is the A. coelom B. pseudocoelom C. hemocoel D. blastocoel E. pseudocoelom?
C. hemocoel
In a grasshopper all the body tissues are bathed in blood that is in the?
In a grasshopper, all the body tissue are bathed in blood that's in the hemocoel. The hemocoel is the main body cavity of the majority of invertebrates.
What is the difference between a coelom and a hemocoel?
Hemolymph is comparable to blood in a closed circulatory system. In open circulatory systems, hemolymph is propelled by a heart through short arteries and into spaces called sinuses surrounding tissues and organs. Hemolymph reenters the heart through pores that are usually equipped with valves. Hemocoel refers to the collective hemolymph-filled body sinuses. The coelom is not the same as the hemocoel, and is usually very reduced in development after the embryo stage. The hemocoel becomes the main body cavity in adults.
What kind of cavity does an arthropod have?
Arthropods have an internal body cavity called a hemocoel which bathes the internal organs in nutrients, and is a component of their open circulatory system.
What is the characteristics of an ARTHROPODS?
Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. They also have an internal body cavity (hemocoel) and an open circulatory system.
Which is a feature of the arthropod body plan?
Arthropods have segmented bodies, an exoskeleton made from chitin, and joint appendages. On arthropods you will observe an internal body cavity called a hemocoel to contain the internal organs which are bathed in hemolymph.
Do butterflies have closed circulatory systems?
The butterfly's circulatory system consists of a long tubular heart and hemocoel (spaces between organsfor blood to move). The blood is pumped out to tissues through the hemocoel, but it simply seeps back through the tissue, and it doesn't carry oxygen, just nourishment. Air enters through pores called spiracles and moves through tubes through the body, with gas exchange occurring at the ends of those tubes (tracheae).(see links below for more information.)
What are the characteristics of the groups of organisms called arthropods?
The taxonomic grouping of arthropods is called a phylum. Among other traits, arthropods are characterized by joint appendages and segmented bodies covered by an exoskeleton made of chitin. They have an internal body cavity called a hemocoel and an open circulatory system.
What do insects have instead of lungs?
Insects have, in their abdomen, introverted appendages wich form a ramificated structure called tracheal system. Air enters from lateral openings of the abdomen called spiracles, which can be closed, and then flows into tracheae and tracheols (ramifications of tracheae) reaching the hemocoel, where gas excanges occur.
Do arthropods have jointed appendages?
All arthropods have jointed appendages. The terms "arthropod" means "jointed foot". Arthropods have segmented bodies and examples of them are insects, spiders, and crustaceans.
Do scorpions have a heart?
Like other arachnids, scorpions have a single tube for a heart. While they have some arteries to deliver freshly oxygenated 'blood' (called hemolymph in creatures with an open circulatory system) to important areas, it is returned grossly to the hemocoel.
What are the five common characteristics of an arthropod?
They are having jointed limbs, a segmented body, an exoskeleton, and a well-developed nervous system. YOUR WELCOME PERSON!
