Earthworms [1]
They are the main contributors to enriching and improving soil for plants, animals and even humans. Earthworms create tunnels in the soil by burrowing, which aerates the soil to allow air, water and nutrients to reach deep within the soil
After organic matter is digested, the earthworm releases waste from their bodies called castings. Castings contain many nutrients that the plant can use
Earthworms are classified in the phylum Annelida or Annelids. Annelida in Latin means, “little rings.” The body of the earthworm is segmented which looks like many little rings joined or fused together
Mention briefly about the circulatory system of an earthworm. [2]
Mention briefly about the circulatory system of an earthworm.. Earthworms (Pheretima) have closed blood vascular systems, which consists of the heart, blood vessels, and capillaries
Blood is supplied by smaller blood cells to the gut nerve cord and the body wall. Blood glands are present in the 4th,5th,and6th segments, which produce blood cells and haemoglobin dissolved in blood plasma

Circulatory system of Earthworm [5]
– In earthworm, the blood vascular system is of closed type.. – Blood vascular system is different in first 13 segments as regards to number, arrangements and nature of blood vessels.
– The respiratory pigment haemoglobin is dissolved in plasma, and hence the blood of the earthworm is red in colour.. – The plasma also includes other corpuscles that are colourless and bear nucleus.
– The vessels are closed tubes and possess definite wall.. – They further break down into capillaries and are divaricated in the various parts of the body.
Life of an Earthworm [6]
What’s it like to be a worm? How would the world look, sound, and feel. if you lived at ground level or below, if you couldn’t control your body
Compare how your body does each of these things with how a worm does. – Seeing: Earthworms have no eyes, but they do have light receptors
– Hearing: Earthworms have no ears, but their bodies can sense the. – Thinking and feeling: Worms have a brain that connects with nerves
What are the two major blood vessels in the earthworm? [7]
What are the two major blood vessels in the earthworm?. The dorsal blood vessel and ventral blood vessel along with the aortic arches supply blood to the organs in earthworms.

The blood consists of amoebic cells and haemoglobin dissolved in plasma.
Earthworms Closed Circulatory System Explained [8]
Earthworms have a closed circulatory system, the same as many other species, such as mammals.. Most insect species have an open circulatory system
Instead, the insects ‘blood’, known as haemolymph, flows freely into the insect’s body cavity.. This system works within smaller animals, such as insects but would not function so well within bigger creatures like mammals
The haemolymph enters this tube and is then pumped up towards the head, where it is then allowed to flow freely. Within the body cavity, the haemolymph is forced forward by the pressure of more liquid being pumped in at the head.

Animal Circulatory System – Frog, Fish & Earthworm [10]
Many animals have a closed circulatory system, where the blood is maintained in vessels and pumped by a heart. Some organisms, such as many mollusks, have an open system, where the blood washes over and around tissues
The blood is also able to travel further than in an open system. These animals may have a one-, two-, three-, or four-chambered heart.
|Number of circuits for circulation||Three||One||One|. Frogs are amphibians and have a closed circulatory system
Circulatory system of earthworm [11]
– The circulatory or blood vascular system of an earthworm is a closed type.. – It consists of the blood vessel, heart, capillaries, and blood glands.
– Blood is red in color due to the presence of respiratory pigment hemoglobin (erythrocruorin) in it.. – Hemoglobin is not contained in the corpuscles like vertebrates but occurs dissolved in plasma.
They are of 2 types: collecting blood vessels and distributing blood vessels.. – They are closed tubes with a definite wall, and they break into capillaries to ramify in the different parts of the body.
Earthworm [12]
|An unidentified earthworm species with a well-developed clitellum|. An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida
In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female. Theoretical cladistic studies have placed them in the suborder Lumbricina of the order Haplotaxida, but this may change.[clarification needed] Other slang names for earthworms include “dew-worm”, “rainworm”, “nightcrawler”, and “angleworm” (from its use as angling hookbaits)
The megadriles are characterized by a distinct clitellum (more extensive than that of microdriles) and a vascular system with true capillaries.[1]. Earthworms are commonly found in moist, compost-rich soil, eating a wide variety of organic matters,[2] which include detritus, living protozoa, rotifers, nematodes, bacteria, fungi and other microorganisms.[3] An earthworm’s digestive system runs the length of its body.[4] They are one of nature’s most important detritivores and coprophages, and also serve as food for many low-level consumers within the ecosystems.
How Many Hearts Does a Worm Have? [13]
How many hearts does a worm have? A good question! The answer to that question, however, can be a little complex since it relies on how you define “heart” or even “worm.” The number of hearts a worm has can range from zero to five to as many as 10. Although worms don’t have the typical human-like heart, they do have five pairs of aortic arches that operate similarly to the heart in humans.
We’ll also break down how worms work and how their other organs keep them functioning.. Let’s concentrate a little on the word “worm.” Biologically speaking, the term “worm” is no longer used in science
Phylogenetically very unrelated species such as snakes, jellyfish, barnacles, and other parasites were included in Linnaeus’ initial categorization of “vermes,” which was based mostly on groups with homologous biological features. In the past, the taxonomic category “worm” served as a type of throwaway taxon; it is a collection of species that were left over but couldn’t be categorically separated into other groups
Circulatory System of Earthworm [14]
Blood-vascular system of earthworm is well developed and consists of closed blood vessels, which are longitudinal and transverse and in which red blood flows continuously.. The blood is bright red in colour due to the presence of haemoglobin or erythrocruorin which is dissolved in plasma
The circulatory system is complicated and arrangement of blood vessels in the intestinal region i.e. behind the fourteenth segment is different from the arrangement in first fourteen
Important transverse vessels in first 13 segments are:. Lateral hearts (Hearts pump blood from dorsal to ventral vessels, these have valves.)
What Are the Seven Organ Systems of the Earthworm? [15]
Earthworms are simple creatures that pack a powerful environmental punch. They live in moist soil, digging tunnels that aerate the soil for plants and processing vegetation through their digestive systems to turn it into nutrients for the plant roots
Their skin must stay moist for the gas diffusion to work properly, which is why they stick to damp soil and don’t usually venture out into the hot sunshine.. An earthworm has a closed circulatory system that uses vessels to send blood through its body
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. Smaller capillaries help the blood absorb nutrients and oxygen or carbon dioxide and carry them to the proper areas of his body.

shown in grey, let us remove these septa for clarity:. Note the dorsal vessel, a single structure, running
Smaller blood vessels (not shown) supply the body wall. Note the pseudohearts (hearts) in segments 7 to 11 (there are five pairs in total, one pair
Circulation in A Giant Earthworm, Glossoscolex Giganteus [17]
The annelid worms stand out among most other invertebrate forms by having a closed vascular system. Their blood usually contains haemoglobin in simple solution as a respiratory pigment
It is surprising to find that the earthworm Glossoscolex giganteas of such great size has no special organs of respiration, the skin being the only surface available for gas exchange. Such a structural arrangement may depend upon specialized adaptations in the pattern of blood flow or in the respiratory characteristics of the blood, or both.
Most of the experiments to be described were done in Sao Paulo, Brazil. giganteas is readily available in the tropical and subtropical regions of Brazil
Overview of the Circulatory System [18]
By the end of this section, you will have completed the following objectives:. – Compare and contrast the organization and evolution of the vertebrate circulatory system.
Simple diffusion allows some water, nutrient, waste, and gas exchange into primitive animals that are only a few cell layers thick; however, bulk flow is the only method by which the entire body of larger more complex organisms is accessed.. The circulatory system is effectively a network of cylindrical vessels: the arteries, veins, and capillaries that emanate from a pump, the heart
In a closed circulatory system, blood is contained inside blood vessels and circulates unidirectionally from the heart around the systemic circulatory route, then returns to the heart again, as illustrated in Figure 1a. As opposed to a closed system, arthropods—including insects, crustaceans, and most mollusks—have an open circulatory system, as illustrated in Figure 1b
