Pharyngeal epithelium cuticle - dorsal blood vessel pharyngeal bulb pharyngeal gland cells
Compliant with septa. Its inner layer is ciliated, folds (1) pre-typhlosolar region: the first or anterior part is the lyi process, the villi, and is highly vascularized. Sections 15 through 26 are known as the Pre-Typhlosol Zone from 26. Its wall is folded internally to form a menu segment, externally further a pair of earthworms feed on vegetation with dead organic matter, especially soil. It also feeds directly on leaves, grasses, seeds, algae press its mouth against the soil and contractile sucking action. The expanded pharyngeal wall draws fragments of soil into the buccal chamber. The form and function of the pharynx in animals is final. It looks like a bead because of the circular vascular and glandular shape.
The intestine is divided into 3 parts: directed lateral conical outflow intestinal ca that runs from the 22nd to the 23rd segment. These are richly vascularized and are projected internally into a villi-like process (2) typhlosolar region: the second or central part lies between the 27th segment up to the 23–25 segment in front of the anus. It is characterized by the presence of a highly glandular vascular longitudinal. The ridge arises as a median in the grove of the dorsal aspect of the intestinal cavity. This is typhlosol cal. (3) Post typhlosolar region: The third or last part, also known as the rectum, is of approximately 23-25 segments. It is internal marked by the presence of longitudinal folds. It opens out through a terminal anus. Mechanism of feeding and feeding from the pharynx to the body wall.
Its walls are highly vascular and glandular and (a) the buccal chamber: the crescentic mouth is located in the abdomen of the Z-01 Zoology prostomium at the anterior end of the peristomium, leading into a narrow protrusive buccal chamber extending to the middle of the third segment . Pharynx: The buccal chamber carries a giant pear-shaped muscle into the pharynx, which extends forward to the segment. Its cavity is somewhat compressed dorsally, producing a salivary secretion due to the presence of a large glandular pharyngeal mass on its roof. The lateral walls of the pharynx are pushed inward forming a narrow horizontal shelf on its side. The two shelves meet front and back, thus dividing the pharyngeal cavity into a dorsal or salivary chamber and an abdominal or conducting chamber. Salivary secretions contain mucus and proteolytic enzymes that are pumped into the salivary chamber.

It extends to the seventh section. (d) Gizzard: The major, oval, rigid and thick-walled muscular organ located in the esophagus eighth segment, modified into gizzard. Its muscular wall consists of circular muscle fibers, it is lined internally by a hard cuticle. (f) Abdomen: After the gizzard is a small narrow tube, the abdomen, which extends from segments 9 to 14, is thrown into the internal transverse folds with a sphincter.
