- Earthworms are hermaphrodites where each earthworm contains both male and female sex organs. The male and female sex organs can produce sperm and egg respectively in each earthworm. Although earthworms are hermaphrodites, most need a mate to reproduce. During mating, two worms line up inverted from each other so sperm can be exchanged. The earthworms each have two male openings and two sperm receptacles, which take in the sperm from another mate. The earthworms have a pair of ovaries that produce eggs. The clitellum will form a slime tube around it, which will fill with an albuminous fluid. The earthworm will move forward out of the slime tube. As the earthworm passes through the slime tube, the tube will pass over the female pore picking up eggs.

Earthworm The gut of the earthworm is a straight tube which extends from the worm's mouth to its anus. It is differentiated into a buccal cavity (generally running through the first one or two segments of the earthworm), pharynx (running generally about four segments in length), esophagus, crop, gizzard (usually) and intestine. Chemical: In addition to dead organic matter, the earthworm also ingests any other soil particles that are small enough—including sand grains up to 1/20 of an inch (1.25 mm)—into its gizzard, wherein those minute fragments of grit grind everything into a fine paste which is then digested in the intestine.

- Worm and Frog Anatomy & Physiology. We study the fascinating body parts of both the worm and frog. Our studies include learning about the anatomy (structures) and physiology (how the structures work).Students compare the two animals noting commonalities and differences. They relate their comparisons to the human body in a future unit. Worm Locomotion Explore how an earthworm moves through the dirt. » Worm's Digestive System This website describes the physiology and anatomy of the earthworm. The digestive system works well here although esophagus is not spelled the way Americans spell it.

Test Bank Of Essentials of Anatomy And Physiology 7th Edition by Martini Bartholomew Systems of the human body. Skin and nails are part of the integumentary system that helps protect the body. Earthworms have organ systems that help them move, breathe, and digest food. The endocrine system is responsible for producing and regulating hormones in the bloodstream to control bodily functions.he torso houses many of the human body's organ systems. The gonads are the organs that produce gametes, or the body's sex cells. The digestive tract is an organ system. The male reproductive system is quite different from the female system.

ANnelida EArthworm. Earthworms lack any kind of special respiratory organs. They breathe through a gas exchange through their skin. This occurs using areas of the body cavity known as cappilary beds.

Nervous system The nervous system and RLS plus free information on the cause and the cure of Restless Legs Syndrome (RLS). The nervous system is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. The central nervous system contains the brain, spinal cord, and retina.

Nervous Systems Although the invertebrate nervous system is usually much simpler than the nervous systems found in vertebrates, there is still a broad range in complexity depending on the type of invertebrate. The simplest type of nervous system is found in hydras and jellyfish (cnidarians) and is referred to as a nerve net..Nerve nets do not have distinct central or peripheral regions, and lack anything that resembles a brain. Instead, the scattered nerve cells form loose networks in each cell layer of the body wall.lthough the invertebrate nervous system is usually much simpler than the nervous systems found in vertebrates, there is still a broad range in complexity depending on the type of invertebrate.

Respiratory System Earthworm. The earthworms' respiratory system is very different compared to other mammals, but the purpose is the same, get the oxygen and take out the carbon dioxide. Earthworms do not have lungs or gills like other mammals, but instead they breathe by using their moist skin.espiratory System. The respiratory system performs exchange between gases. The molecules of oxygen and carbon dioxide are exchanges, this process changes oxygen to carbon dioxide. Our respiratory system is responsible to clean out the bacteria or dust we breath in.

Nervous system Nervous system. The nervous system is the part of an animal's body that coordinates its actions and transmits signals to and from different parts of its body. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago.

It conducts respiration through its skin.arthworms are hermaphrodites, that is, they have both male and female sexual organs. The sexual organs are located in segments 9 to 15. Earthworms have one or two pairs of testes contained within sacs. The two or four pairs of seminal vesicles produce, store and release the sperm via the male pores.

Clamworms The earthworm also has a pharynx, esophagus, crop, gizzard and intestine. When the worm eats its food, it pulls the materials into its mouth with the help of the pharynx and its prostomium (also called acron). This creates a suction motion. This suction motion aids in helping the worm consume large amounts of food in a sort amount of time. The gizzard grinds the food.

- Excretory System. Part of an earthworm's excretory system is directly connected to his digestive system, as the intestines pass waste through the anus and out of the worm. This poop is called castings, and it serves as a type of plant fertilizer.However, some of the waste is picked up by excretory cells and carried outward to the skin.n earthworm has a closed circulatory system that uses vessels to send blood through its body. There are five aortic arches throughout his body that serve as pumps. The dorsal vessels take blood from the back of his body to the front, and the ventral vessels take blood the other direction, from front to back.

- The term earthworm is commonly assigned to certain worms in the class Clitellata in the phylum Annelida. Annelid worms are distinguished from other important worms like nematodes by having a coelum or true body cavity, a circulatory system, and a body divided into segments.

Platyhelminthes flatworms Flatworms are unsegmented, bilaterally symmetrical worms that lack a coelom (acoelomate) but that do have three germ layers. Some forms are free living but many are parasitic.Flatworms have a cephalized nervous system that consists of head ganglion, usually attached to longitudinal nerve cords that are interconnected across the body by transverse branches.onparasitic forms have a simple, incomplete gut; even this is lacking in many parasitic species. Movement in some flatworms is controlled by longitudinal, circular, and oblique layers of muscle. Others move along slime trails by the beating of epidermal cilia.
