Cephalization
Cephalization refers to the clustering of sensory structures at the anterior end of an organism, leading to the development of a head region with specialized sensory organs such as eyes, ears, and mouth. This organization is commonly seen in bilateral animals and is associated with increased mobility and complexity.
Body symmetry and cephalization are both animal evolution trends, and both are primarily seen in more complex animals (think humans rather than sponges). Therefore, both enhance the complexity and speed of an animal's response. Body symmetry and cephalization give an animal an advantage of better and more convenient usage of its senses and body parts.
All of these are included in two of the human body systems:The Lymphatic System and the Immune System.Lymphatic System:Lymph nodesSpleenThymusBone marrowLymphatic vesselsLymphoid tissues in the Digestive System (e.g., lymphoid follicles, Peyer's Patch, appendix) aka MALT~Mucosal Associated Lymphoid Tissue aka GALT~Gut Associated Lymphoid Tissue.TonsilsImmune System:Lymph nodesSpleenThymusBone marrowLymphatic vesselsLymphoid tissues in the Digestive System (e.g., lymphoid follicles, Peyer's Patch, appendix) aka MALT~Mucosal Associated Lymphoid Tissue aka GALT~Gut Associated Lymphoid Tissue.TonsilsAdenoidsBlood cells ~ WBC, RBC, PlateletsAntibodiesB-CellsT-CellsSkin aka CALT~Cutaneous Associated Lymphoid Tissue)
The circulatory system is most closely associated with transport and delivery in the body. It is responsible for transporting nutrients, oxygen, and hormones to cells, as well as removing waste products from the body.

Cephalization
A hydra does not have cephalization.
Cephalization refers to the concentration of sensory and neural structures in the head region of an organism. Generally, animals with a higher degree of cephalization tend to exhibit more complex behaviors and cognitive abilities. This is because a concentrated nervous system in the head allows for more efficient processing of information and is often associated with higher levels of intelligence.
The mesoderm and cephalization are characteristics associated with all animals that display bilateral symmetry at some point in their lives. The mesoderm is a germ layer and cephalization is when nervous control and sense organs are located in an organism's head.
The cephalization of a mollusca could possibly describe the arrangement of neurons in the front end of the animal.
Cephalization means formation of a head. Cnidarians have no head, so no.
Animals with cephalization respond more quickly and in more complex ways.
Deuterostome coelomates are divided into 2 groups : the epithelioneurians and the epineurians/chordates , Epithelioneurians (whose nervous system is a network of nerve fibers related with the epithelium) have a rudimentary cephalization

Yes. They have extensive cephalization. They have a brain and eyes.
