Which segments lack nephridia?
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
Water and nutrients are reabsorbed from the nephridia into?
The water and nutrients are reabsorbed from the nephridia into the blood vessels surrounding the nephridia. This process helps to conserve essential substances and maintain the balance of fluids and solutes in the body.
How do annelids excrete cellular waste?
An annelid excretes solid waste through its anus. However, metabolic wastes are excreted by its nephridia, a pair of organs.
What does nephridia remove what substance from the body?
Nephridia remove metabolic wastes, such as nitrogenous compounds (e.g., ammonia), from the body by filtering them from the coelomic fluid and releasing them outside the body.
What is the excretory system of annelids?
NEPHRIDIA:- In earthworm excretion occurs through nephridium. The excretory system in earth worm is closely associated with its closed circulatory system. Each segment of earthworm consists of a pair of nephridia or in some species cluster of nephridium. NEPHRoSTOME:- The colemic fluid or body fluid enters the nepridium through a membrane which is cilliated called nephrdiostome. NEPHRIDIOPORE:- The body fluid after reabsorption from the nephridia opens into a large bladder which opens to exterior through nephridiopore. Ammonia and water are waste products excreted by nephridia while CO2 is excreted through general body surface.
Which segments lack nephridia?
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
Water and nutrients are reabsorbed from the nephridia into?
The water and nutrients are reabsorbed from the nephridia into the blood vessels surrounding the nephridia. This process helps to conserve essential substances and maintain the balance of fluids and solutes in the body.
What is the organ which cleans a mollusks hemolymph?
nephridia

What phylum includes worms that excrete by means of nephridia?
The phylum Annelida includes worms that excrete waste through structures called nephridia. Nephridia are tubular structures that filter waste from the coelomic fluid and release it outside the body through pores called nephridiopores.
Is the nephridia involved in the absorption on nurtients in a starfish?
Yes.
What are the organs of the simple excretory systems of earthworms?
nephridia
What human organ do the nephridia of the earthworm correspond?
Kidney
The green glands in a crayfish is homologous to what organ in the earthworm?
nephridia
What are the organs of the simple excretory system of earthworms called?
nephridia
Which of the parts of the worm's body includes in the excretory system?
An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.
What parts of an earthworms body are in the excretory system?
The excretory system of a worm is comprised of three pairs nephridia. Each type of nephridia, the integumentary, septal, and pharyngeal, is located in a different segment.
