Helps to keep the surface of the earthworm moist.
and this is the dorsal view
Yes, heart lies superficially and more like centrally, over the diaphragm.
The abdominal aorta provides oxygenated blood and nutrients to the lower half of the bodyThe abdominal aorta is the final section of the largest artery in the body. It supplies oxygenated blood to the abdominal organs, pelvic organs, and the legs.
The dorsal side of an earthworm is darker than the ventral side because of the dorsal blood vessal that runs along the top of the digestive track and just under the skin. There is a ventral blood vessal, but it doesn't lie against the skin, but instead in between the ventral nerve cord and the digestive track.
The actual "pumping system" of a worm can be mistaken as a heart, but it has no chambers. They are actually aeortic arches that pump the blood down the ventral side of the worm and it returns on the dorsal vessel.
Function of Anal-pore
you have to answer my question
A pore which protozoa use to eat their prey.
the dorsal blade is used to help steer and to cut through the water easier without the dorsal fun the dolphin would just kinda float there. I hope that was helpful in anyway
a pore in the outer wall of a spore or pollen grain through which the germ tube or pollen tube makes its exit on germination stoma, stomate, pore - a minute epidermal pore in a leaf or stem through which gases and water vapor can pass
you sweat through pores and your hair grows through them
To carry the blood to all parts of the earthworm.
it carries blood from the dorsal blood vessel to the ventrical blood cell
The main function of the dorsal fin in any animal with a dorsal fin is stability. Some fish have adapted for using the dorsal fin for other uses, such as propulsion in the Sunfish. The anglerfish's dorsal fin has evolved to work as a fishing pole so that the fish can bait and catch their prey.
They help to allow the clams to filter feed.
