Most animals don't have red blood. Those that do have red blood are most of the vertebrates. Some fish, especially cold-water fish, lack hemoglobin. Octopi have copper-based green blood. Insects and other arthropods' blood is called hemolymph, which is not pigmented as a rule. Earthworms have red blood that, interestingly enough, does contain hemoglobin. Most other annelids do not have red blood. Echinoderms (starfish, sea lilies, and sea cucumbers) do not have blood. Neither do sponges, coelenterates, and flatworms.
What else can I help you with?
The vascular system in plants is analogous to what system in animals?
The vascular system in plants is analogous to the circulatory system in animals. Both systems are responsible for the transportation of fluids and nutrients throughout the organism. In plants, the vascular system consists of xylem and phloem, while in animals, the circulatory system includes the heart, blood vessels, and blood.
Do mollusks have a closed circulatory system?
No, mollusks typically have an open circulatory system, where the blood flows around the body cavity and directly bathes the organs. This is in contrast to closed circulatory systems found in some other animals where the blood flows through vessels.
What animals have a single circulatory system?
Invertebrates like insects and mollusks have a single circulatory system. This system does not differentiate between oxygenated and deoxygenated blood, instead using a fluid called hemolymph to transport nutrients and waste throughout the body.
What type of circulatory system do spiders have?
Spiders have an open circulatory system. This means that their blood, called hemolymph, flows freely within their body cavity instead of being contained within blood vessels like in animals with closed circulatory systems. Hemolymph plays a role in nutrient transport, waste removal, and exerting pressure to help with movement in spiders.
What is a single loop circulatory system?
A single loop circulatory system is a type of circulatory system found in some simpler animals, where blood flows through the body in one continuous loop. This type of system lacks separate systemic and pulmonary circuits, with blood traveling from the heart to the gills or lungs, then to the rest of the body, and back to the heart. Examples of organisms with a single loop circulatory system include fish.
Animals with a closed circulatory system?
Example of closed Circulatory animals is worms
What are examples of animals with an open circulatory system?
grasshoppers, have an open circulatory system
How is carbon dioxide part of the circulatory system?
It helps plants and animals live. It also is apart of the circulatory system.
What type of circulatory system do animals that use lungs for breathing have?
A circulatory system that involves the lungs is referred to as a double circulatory system. This is opposed to a single loop circulation that fishes have.
Does a garter snake have a circulatory system?
yes, it has a open circulatory system, which is not contained within veins.
In animals that lack a circulatory system how are materials transported?
diffusion
How are materials transported for animals that don't have a circulatory system?
Diffusion.
Which animals have open circulatory system toads or prawns?
prawns
How do animals with no circulatory system get their material needed?
By simple diffusion
Is the circulatory system open or closed?
Some dont have any at all but most have closed cirrculatory systems.
What animals have a double circulatory system?
Arthropods and most mollusks have an open circulatory system.
Does a dandelion have a circulatory system?
No, plants don't have circulatory systems as we do. Advanced plants such as dandelions do have a vascular system: xylem to carry water up from the roots and phloem to carry sugars down from the leaves, but there is no pump like our heart.
