How do arthropods produce red blood cells?
Arthropods don't actually use red blood cells, nor hemoglobin; the arthropods that use oxygen-carrying molecules in their circulatory fluid (hemolymph) use hemocyanin, a copper-based protein rather than iron-based like hemoglobin. It's also not bound to cells but drifts around in the fluid. When oxygenated it turns a bluish color. Note that the oxygenation strategy for most (but not all) arthropods is to get oxygen directly from the air, through openings in their segments (spiracles) that connect to a trachea and to smaller tubules connected directly to tissues, thus bypassing a liquid circulatory system.
Do arthropods and mollusks have lungs?
No for arthropods; yes for some molluscs. The larger aquatic arthropods like lobsters and crabs accomplish gas exchange using gills. Smaller ones like the land-based insects have holes (spiracles) in the exoskeleton and a tube system to facilitate gas exchange necessary for respiration. In this case, unlike mammals which use lungs to oxgenate blood which is pumped to the tissues, the tracheal tubes from the spiracles deliver oxygen directly to the tissues. Aquatic molluscs have gills for gas exchange whereas molluscs adapted to live on land like snails do have a lung.
Why is the way an organism gets oxygen not a characteristic of arthropods?
Arthropods do in fact have an aerobic metabolism requiring oxygen, though it differs from our own. The strategy to acquire it varies depending on environment; marine arthropods like crabs and lobsters have gills to extract it from water; crabs on land can still use gills if they remain moist. Insects, which constitute the bulk of the phylum, get it directly from the air through holes in their body segments (spiracles); the air gets conducted directly to the tissues via tubules and thus do not use a fluid circulatory system for that purpose. Those arthropods that do use their circulatory system for oxygenation exploit hemocyanin, a component in their body fluid (hemolymph) to which oxygen can bind, comparable to a mammal's hemoglobin. Unlike us, this oxygen carrying molecule is not bound to proteins in blood cells, but drifts around freely in the hemolymph. The circulatory system for both those arthropods that oxygenate directly from air or oxygenate using hemolymph, is described as an "open" one, with the organs bathed in the fluid in a body cavity called a hemocoel.
How do arthropods exchange gases?
There are several methods arthropods use for gas exchange; insects have holes in their segments called spiracles, connected to a trachea and tubules which deliver oxygen directly to tissues without needing to go through a bloodstream; and also remove waste gasses. Arachnids may use a type of simple lung called a book lung, comparable to a book gill in a similar stacked spatial arrangement for some aquatic arthropods. Other marine arthropods use gills for gas exchange, such as crabs and lobsters; crabs can continue to use gills on land so long as they remain moist. The simpler and smaller arthropods are able to perform gas exchange across their entire body surface and need no additional specialized gas exchange structures.
What is an animal that uses book lungs?
spiracles?Spiracles are tiny holes on an insects abdomen used for respiration.Arachnids are the class of Arthropods that use book lungs for respiration. Although the class is divided into Pulmonate Arachnids (Contain book lungs) and Apulmonate Arachnids (Lacking book lungs).The horseshoe crab has book gills which evolved into book lungs in other creatures.
What do insects use their Spiracles for?
They breathe through it
What breathing system does wasp use?
Spiracles.
Names of animals that breathe through breathing tubes?
Insects use tracheal system of breating not animalsand who the animal ?Insects do not breathe through their mouths as we do. The do not have lungs and their blood, which is a watery, yellowish liquid, does not carry oxygen and carbon dioxide around their bodies.Insects have a system of tubes, called tracheae, instead of lungs. These tracheae penetrate right through the insect's body. Air enters the tracheae by pores called spiracles. These spiracles are found on each side of the insect's abdomen. Each segment of the abdomen has a pair of spiracles.
Blood circulation of an arthropod?
Arthropods do have circulatory fluid called hemolymph, containing nutrients to nourish the internal organs and cells. They have open circulatory systems, with the internal organs bathed in this fluid, in a body cavity called a hemocoel. Hemolymph differs from our blood in significant ways; in arthropods, there is no distinction between what we think of as blood and what we would consider lymphatic fluids. Also, for those arthropods that use hemolymph as the oxygen carrier, they don't use hemoglobin like our red iron-based blood; instead they use the copper-based hemocyanin. Hemocyanin is not bound to proteins on blood cells but floats freely around in the fluid. It is greyish in color but when oxygenated turns somewhat blue. Insects don't use hemolymph to carry oxygen - they elimintate waste gas and oxygenate tissues directly from the air, drawn through a trachea into tubules from external holes (spiracles) in their body segments. Both this strategy and oxygenation using hemolymph is often assisted by the organism's movements. Arthropods do have a kind of heart, a dorsal tube, which draws the fluid in from open ended pores in the hemocoel called ostia.
Why can't arthropods be large?
Their exoskeleton limits growth; if arthropods were large, their armour would be too heavy and they'd collapse! Also they use trachea to absorb oxygen, and if they were large, these wouldn't reach through their entire body and cells would die off in areas further away from the oxygen supply. This is why they did get large in the Carboniferous era, when oxygen concentrations in the atmosphere were much higher. :)
Does a flatworm have an open or closed circulatory system?
Arthropods have an open circulatory system, with organs in the internal body cavity (hemocoel) and cells bathed in hemolymph. The fluid drains into open pores for recirculation usually by a dorsal tube acting in the role of a heart. Not all arthropods use hemolymph for oxygenation; insects for example oxygenate tissues directly via tubules connected through vents (spiracles) to the atmosphere.
