Noun.
Do jellyfish have true tissues?
Although they have specialized cells for particular functions, they lack true tissues in which specialized cells are organized into functional groups. The cnidarians, or the jellyfish and their kin, are the simplest animal group that displays true tissues, although they possess only two tissue layers.

Which animal is most likely to have an open circulatory?
Animals With an Open Circulatory System These open systems are found primarily in arthropods and mollusks. Arthropods are a group of animals that includes insects and crustaceans. Mollusks are organisms such as clams, snails, and oysters.
Which animals have no closed circulation?
The simplest animals, such as the sponges (Porifera) and rotifers (Rotifera), do not need a circulatory system because diffusion allows adequate exchange of water, nutrients, and waste, as well as dissolved gases.
What organ removes sugar from the blood?
Glycogen is mainly stored in the liver (where it makes up as much as 10% of liver weight and can be released back into the blood stream) and muscle (where it can be converted back to glucose but only used by the muscle). Therefore, excess glucose is removed from the blood stream and stored.

How is blood formed in our body?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
