Nematodes lack respiratory and circulatory systems. Living organisms perform circulation in different ways. Mammals rely on blood vessels, trees have tiny openings in their trunks, and nematodes utilize a process . The digestive system is incomplete in most species. Similar to nematodes but no excretory pore or lateral chords.
Circulatory system nematodes have a separate circulatory system .
These worms have a complete digestive system and are more complex than the flatworms (phylum platyhelminthes) but lack a circulatory system and other . B) thick walled muscular gut. Similar to nematodes but no excretory pore or lateral chords. Nemertea, also flattened worms, but have circulatory system and anus; The excretion of nitrogenous waste though within the nematoda phylum is not nearly as structured. Sarah larsen 5/19/09 period 4. Living organisms perform circulation in different ways. Nervous system a network of cells. Longitudinal muscles (no circular) underlie cuticle. They lack circulatory and respiratory systems, and have a rudimentary excretory system. Nematodes lack respiratory and circulatory systems. Allows circulation of gasses, food and wastes in the absence of a circulatory system. Circulatory system nematodes have a separate circulatory system .

They have a complete digestive system. The absence of circulatory system in nematodes is compensated by the presence of: These worms have a complete digestive system and are more complex than the flatworms (phylum platyhelminthes) but lack a circulatory system and other .
