Where does gas exchange occur in terrestrial arthropods?
Terrestrial arthropods have a series of openings called spiracles at the body surface. Spiracles open into tiny air tubes called tracheae, which expand into fine branches that extend into all parts of the arthropod body
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 arthropods have backbones?
Do arthropods have backbones?No, it is the exoskeleton that holds the arthropod's body together. arthropods are invertebrates, which means they do not have backbones.
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.
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.
How do nuetrions move from one place to the other in a arthropods?
Arthropods have a body plan that includes an internal body cavity called a hemocoel, with the organs and cells bathed in a fluid called hemolymph. This fluid combines the functions of lymph and blood as in vertebrates. It is rich in nutrients: carbohydrates like sugars, protein, fats, etc. The fluid circulates mostly by draining into special pores and being drawn up by a dorsal heart to be distributed. Because of the simplicity of this system some advantages are gained but it is difficult to divert the hemolymph to a specific location. The body movements assist in distribution of the fluid.
What is the hard shell of an arthopod called?
That is called the Exoskeleton. It is an external skeleton that protects the body of arthropods.
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.
What is the jelly like fluid that fills the eyeball called?
Aqueous humor is a clear, watery fluid continually produced inside the eye. The aqueous humor is made by the ciliary body.
What is the clear body fluid that pays the cells and transports lymphocytes?
Lymph
How do arthropods move nutrients from one parto f the body to anohter?
Arthropods do have a circulatory system to move oxygen and nutrients through their bodies, but it is an open design, meaning the organs and cells are bathed in circulatory fluid unlike our circulatory system which delivers blood to specific locations. Their internal body cavity is called a hemocoel, the fluid drains into open pores and is pumped by a simple dorsal heart. Their movements also help to move the fluid around. This liquid is called hemolymph and contains water, salts, proteins, carbohydrates and lipids, and an oxygen-carrying molecule.
What type of cyrculatory system do arthropods have?
Arthropods have open circulatory systems, with the internal organs bathed in a fluid called hemolymph, in an internal body cavity called a hemocoel. For hearts, arthropods have a dorsal tube that draws the fluid from open-ended pores (ostia). This fluid differs from our blood in significant ways; in arthropods, there is no distinction between what we think of as blood and lymphatic fluids. Also, for those arthropods that have gills and use hemolymph as the oxygen carrier (some have no gills and get oxygen directly from tubes connected to the air, or have book lungs like the arachnids), 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.

What is the hard shell of an arthopod?
That is called the Exoskeleton. It is an external skeleton that protects the body of arthropods.
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.
Do arthropods have tissues?
Yes, arthropods have tissues. These tissues are organized into different organs and systems that perform specific functions in the body, such as digestion, circulation, and movement.
