What structure in the eathworm has a similar function as the human heart explain? Best Answer: The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm. These vessels are the aortic arches, dorsal blood vessels, and ventral blood vessels. The aortic arches function like a human heart. There are five pairs of aortic arches, which have the responsibility of pumping blood into the dorsal and ventral blood vessels. The dorsal blood vessels are responsible for carrying blood to the front of the earthworm’s body.

What type of circulatory system do earthworm's have? Closed circulatory systems (evolved in echinoderms and vertebrates) have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities. Blood flow is not sluggish.losed circulatory systems (evolved in echinoderms and vertebrates) have the blood closed at all times within vessels of different size and wall thickness.

- Note: The structure and function of the heart and other aspects of the vascular system is part of training in therapies such as massage incl. Indian Head Massage, Swedish Massage, acupressure massage, aromatherapy, acupuncture, shiatsu, and others.t is located in the upper body (chest area) between the lungs, and with its pointed end (called the apex) downwards, forwards, and pointing towards the left. The main purpose of the heart is to pump blood around the body. The basic structure of the heart (illustrated above) may be described as follows:

How can I keep woodpeckers from pecking my house? Provide a food source. Some people put out suet and nesting boxes well away from where the birds are pecking so the birds will be attracted to a better, tastier spot away from their homes. However, others claim this method can backfire and the additional food source can end up attracting even more woodpeckers!

Earthworm An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. Earthworms are commonly found living in soil, feeding on live and dead organic matter. An earthworm's digestive system runs through the length of its body. It conducts respiration through its skin. It has a double transport system composed of coelomic fluid that moves within the fluid-filled coelom and a simple, closed blood circulatory system. It has a central and a peripheral nervous system. The central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve cord running back along its length to motor neurons and sensory cells in each segment.

Heart The size of the heart varies among the different animal groups, with hearts in vertebrates ranging from those of the smallest mice (12 mg) to the blue whale (600 kg). In vertebrates, the heart lies in the middle of the ventral part of the body, surrounded by a pericardium. which in some fish may be connected to the peritoneum.

- Circulatory systems may be open or closed. Allvertebrates have a closed circulatory system, in whichblood circulates away from the heart in arteries andback to the heart in veins. The circulatory system servesa variety of functions, including transportation,regulation, and protection.

- The five aortic arches are the pumping organs of an earthworm.s 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.

Heart valve Heart valves are situated around the fibrous rings of the cardiac skeleton. The valves incorporate leaflets or cusps, which are pushed open to allow blood flow and which then close together to seal and prevent backflow. The mitral valve has two cusps, whereas the others have three.

The Structure of the Heart It is essential that blood flows in the correct direction through the heart so the structure of the heart includes a series of valves. 1  The Tricuspid valve separates the right atrium from the right ventricle.  The Pulmonic / Pulmonary valve separates the right ventricle from the pulmonary artery.

What Are the Seven Organ Systems of the Earthworm? An earthworm has a closed circulatory system that uses vessels to send blood through its body.

- a herring-bone effect. Inside the longitudinal muscle is a layer of connective tissue and a layer of flattened epithelial cells (not visible in. this section) that forms the innermost lining of the body wall and the lining of the coelom and is called the peritoneum. The earthworm body wall is richly supplied by blood. Capillaries (tiny blood vessels) form loops inside the body wall, extending to just. beneath the epidermis.

Heart Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid.

Heartworm Disease in Dogs It is caused by a blood-borne parasite known as Dirofilaria immitis. Adult heartworms are found in the heart and adjacent large blood vessels of infected dogs. Rarely, worms may be found in other parts of the circulatory system. The female worm is 6 - 14 long (15 - 36cm) and 1/8 wide (5mm). The male is about half the size of the female.

Structure of the Heart Structure of the Heart. Although most people know that the human heart doesn’t bear much resemblance to a heart drawn on a Valentine’s Day card, the image can still be a useful way to learn and remember the parts of the heart. The heart consists of four chambers: two atria on the top and two ventricles on the bottom.

Digestion An earthworm 's digestive system consists of a mouth, pharynx, esophagus, crop, gizzard, and intestine. The mouth is surrounded by strong lips, which act like a hand to grab pieces of dead grass, leaves, and weeds, with bits of soil to help chew. The lips break the food down into smaller pieces.

The Earthworm. The Earthworm. Phylum: Annelids. INTEGUMENTARY. The earthworm's integumentary system is similar to Human's respiratory system. It uses diffusion/osmosis to rid of carbon dioxide, and take in oxygen. Texture : The earthworm's texture is always moist with mucus. this mucus assists with diffusion, as well as movement.
