Amphibians exchange their CO2 and O2 threw their skin. That's why most frogs have the slime on them bc it helps w this process.
According to my Snapple cap, The common garden worm has 5 pairs of hearts
to keep them selfs wet(the hair mantains water on it)then they wont die from dehighdgeration because they cant stay to dry
Septums help separate an earthworm's internal cavities into sections of different organs.
When the circular muscles contract, they make the worm skinnier. When the longitudinal muslces contract, they make the worm shorter. This series of movements allows for the worm to move forward.
Yes. Earthworms have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
An earthworm does not have any heart at all. But they do have an organ that acts similarly to a heart and is usually called a heart just for simplicity's sake, although is is also called an aortic arch. Earthworms have five of these arches. In between each arch is a gland that helps the worm digest calcium, which it gets from eating a lot of dirt. size The heart and calciferous gland section makes up less than five percent of an earthworm's total body length, no matter how big the individual worm gets.
Function
The aortic arches (hearts) help pump blood around the body of the earthworm in a similar way to animals that have only one multi-chambered heart. Worm "hearts" don't have chambers. Worms also don't have lungs. They absorb oxygen through their skin and then it gets into their blood vessels. The dorsal blood vessel does a bit of the pumping work, with the hearts helping to keep blood pressure steady.

If you're talking about the broad band about one-third down its body - it's called 'the saddle'
Similar to that of a slug, the worm would die and who ever done the deed would be thought of as one of them cruel kids to avoid.
There are several differences between the male and female nematodes. Males usually have straight tails while the females have a curvier tail. Males are usually around 10 in., while females are usually around 11 in. Females also usually have bodies about a half-inch wider than the males. When looking under a microscope, the males have spicules on the center of their undersides.
its a band of thickened, specialized segments in annelids that secrets a mucus ring into which eggs and sperm are released
No. the earthworm has red blood like you an i. Who would think that insects blood-not-normal that means blood you don't see everyday is a completley i am a teacher 28 year old primary school in England but i am french called Emily which in french Is Emi
Ja'ma appelle emi!
Thx
The ORAL CAVITY: Mouth, Tongue, Pharynx,
The earthworm's body allows oxygen to be diffused from the air through the skin. Since, they do not have lungs.
As with most creatures the feeding organ of an earthworm is the mouth. Located behind the mouth is the pharynx which acts as a suction pump; its muscular walls draw food back.
