Annelids have two kinds of respiration depending on different classes. If annelids live in sea or water like annelids in class Polychaeta, they have gills to breathe. Some annelids do not have lugs like earthworm (class Oligochaeta), and they use their outer skin to exchange gas.
Respiration. In some annelids, including earthworms, all respiration is via the skin. However, many polychaetes and some clitellates (the group to which earthworms belong) have gills associated with most segments, often as extensions of the parapodia in polychaetes. The gills of tube-dwellers and burrowers usually cluster around whichever end ...
The annelid phylum is a phylum of over 17,000 different species of segmented worms found in moist environments such as underneath the ground and in tidal zones Earthworms The earth worm is one annelid you may see daily.
Respiration in annelids occurs primarily through their moist skin, although certain species have evolved specialized gills or use paired projections called parapodia in gas exchange. The annelid excretory system consists of paired nephridia found in each segment which function in excreting nitrogenous waste.
Annelid: Annelid, any member of a phylum of invertebrate animals that are characterized by the possession of a body cavity (or coelom), movable bristles (or setae), and a body divided into segments by transverse rings, or annulations, from which they take their name. The coelom is reduced in leeches, and
Phylum Annelida Digestive & Respiratory Systems. Chapter 26 / Lesson 15. Lesson; Quiz & Worksheet - Annelida ... Respiration. Simply put, respiration occurs through annelid skin.
The annelid bauplan: Respiration: The oligochaetes and the leeches by and large exchange respiratory gases directly through the skin and have no special respiratory organs. For oligochaetes living on land, it is crucial that the body surface be kept moist to allow gas exchange to occur. Some aquatic annelids have thin-walled, feathery gills ...
Respiration in annelids can be cutaneous or branchial. Cutaneous respiration occurs through the large amount of veins under the epidermis. Gills are present in aquatic annelids are located in the parapodia (false claws), which have an extensive network of capillaries.
ANnelida. Phylum consisting mostly of segmented worms; Consists of 12,000 species; Very diverse in their head and locomotory appendages; The three species are: earthworm, european medical leech, and the clam worm ... which is specifically made for respiration. The hemoglobin is then transported by the blood throughout the leech. clam worm.
