Digestive system digestive
of earthworms. In the shape of a tube on the plain. That connects from the mouth in the first box until the anus. Which contains the organ:
1.Mouth (Mouth) under the upper lip. The entrance of food. Lead, which is the area with oral salivary glands produce of casting slip in a food, oral cavity is located in the segment that 1 - 3
2.The pharynx (Pharynx) is the muscle thickness and mucus glands, located between the driving segment 3 to articulate that 6 earthworm used pharynx. Vacuum food. In mouth by the contraction of the muscle.
3.The esophagus (Esophagus) between the segment that 6 to articulate that 14 glands cal me ferrous help the sleep of the calcium from the soil mixed with a lot of food imports to the gastrointestinal tract. To prevent the calcium in the blood, too.Only then will the cal. Ferrous. From the esophagus will grow into tubes, lodging, food, a bag of thin walls and brains, which is the muscle strength and functional food grinder thoroughly to forward to the intestines
.4.The intestines (Intestine) is a straight pipe segment at the start of 14 go to the anus. Intestinal wall of earthworm quite thin and intestinal top is folded inside the passageway is called Typhlosole food.For freshwater earthworm no Typhlosole intestinal layers is composed of peritonitis. Swiss เซอรอล is the outermost layer of the intestines, adjacent to the slot body. Certain cells on tissue will change into special cells calledActing like the liver of animals is high. Synthesis and property is the glycogen, fat, fat cells in the tissue. By RA โกเจ with full size will fall in the channel body called. Eleocytes which are distributed toA pull out of the protein extract amino acids, ammonia, urea, and extract silica from food to eat, and then excreted outside the body through the hole to drive. Taking waste or nephridia, next to the diaphragm in seconds.The muscles in the intestines of earthworm contains 2 muscles. The inner circumference and the outer muscle is a muscle longitudinal Alternate with the muscles of the body wall. And the innermost layer of the intestinal lining is intestines.Rod cell and cell glands. Generating function of various types of gastric juice
.
, the digestive systemThe main organ excrete waste in earthworms are nephridia (Nephridia) which is a separate organs function of waste liquid from dates in earthworm body of each segment. The earthworm is nephridia of a coil passes through each segment 1.A collection of fluid in the channel segment next to in front of the torso. The liquid will enter dates in the end pipe nephrostome, cilia surrounding and flow to the various parts of the pipe.The bloodstream. The parts of the nitrogenous base will be expelled to the outside of the box. On the nephridiopore stomach
.Blood circulation
.A closed circulatory system is not divided, arteries and veins by earthworm will use the (Vessel) in the distribution of blood around the body directly. In which the transport systems blood of earthworms.The line is 3 vessels after the middle vein under the intestines. And blood vessels in abdomen and the side of the nerves, blood vessels and by 3 will lay along the length of the body, there will also be a line. The blood side.13 segment is the big squeeze shrink very well known as artificial heart (Pseudoheart) whole blood hemoglobin is dissolved or may not have it!
