Why do worms have 5 hearts?
Worms don't have five hearts; they typically have a simple circulatory system with one main "heart" called an aortic arch that pumps blood throughout their body. The misunderstanding may have arisen due to the segmented structure of their bodies, with each segment containing a pair of aortic arches that may be mistaken for multiple hearts.
Does a bee have a heart?
. my son asked me this question this morning over breakfast, and to the best of our research, bees apparently have some sort of respritoty muscle which controls breathing and circulation. They do have an aorta, so there is such a thing as bee blood, but no heart to pump it through.Additional informationActually bees do have a heart. We humans and other vertebrate animals have a closed circulatory system where blood is pumped through arteries to capillaries then via veins back to the heart, and blood anywhere else in the body is bad news. On the other hand insects, including bees, have an open circulatory system where the blood (for insects more properly called haemolymph) fills all of the body spaces and is not confined to blood vessels. The heart is an elongated organ lying just under the roof of the abdomen. It has muscular walls and is pierced by five pairs of openings with one-way valves which allow blood to enter the heart when it dilates. These valves close when the heart contracts and the blood is forced forwards into the aorta which passes through the thorax and into the head where its open end lies just below the brain. There is a pulsating vesicle at the base of each antenna, forcing the blood to circulate through them. These are the only blood vessels in the bee.From the head, the blood passes back through the thorax, nourishing the flight muscles, then into the abdominal cavity where more nourishment is picked up from the digestive system before it is drawn into the heart again.Insect blood is different from ours. It is a pale straw colour, not red, because there is no haemaglobin. This is because it is not used to carry oxygen to the tissues, that is the job of the tracheal system of respiration.
How many brains does a worm have?
Most worms, like earthworms, have a simple nervous system with a collection of ganglia that act like primitive brains. Earthworms have a cerebral ganglion, which functions like a brain, located near their mouth. So they have one main brain-like structure.

What are the five vertebrate groups characteristics?
The five vertebrate groups are mammals, birds, reptiles, amphibians, and fish. Some characteristics of vertebrates include having a backbone or spinal column, bilateral symmetry, a well-developed brain, and an internal skeleton made of bone or cartilage. Vertebrates also have a closed circulatory system and are typically capable of complex behaviors.
What are all the organ systems?
There are eleven main biological systems in the human body. Five of the most common systems are the skeletal system, muscular system, digestive system, respiratory system, and circulatory system. Five different body systems would be: the excretory system, the immune system, the reproductive system, the nervous system, and the respiratory system. They each have their own way of carrying out bodily functions, and all keep life going on.
Circulation in the earthworm is accomplished through?
The blood circulatory system of the earthworm consists of five main blood vessels; it has aortic arches instead of a heart. The coelom also circulates food, so it could be considered a digestive system or a circulatory system.
