What is another name for nephridia?
There are several other names used when referring to nephridia. Some of these include metanephridium, protonephridia, and metanephridia. It is basically an invertebrate organ that performs similar functions as the kidney.
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.
What does nephridia remove what substance from the body?
metabolic wastes
How do the excretory process to your body?
In human body, the excretion is necessary.there are some organ which perform this function eg.Kidney which filter urea from blood,urea is a nitrogenous waste which is harmful for human body. There are some other organ which involve in excretion in invertebrate like malpighian tubles and in earthworm by nephridia.
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.

What parts of the worms body is included in the exceretory 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.
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.
Organs that remove metabolic waste from an animal's body are called?
Nephridia
What are nephrida?
if you mean nephridia (an extra 'i' second to end) they are specialised organs that function similar to kidneys in that they are used for osmoregulation and excretion. In annelids (which are segmented worms) there is one pair of nephridia per segment.
What is the main excretory organ in the mammal?
The excretory system contains a pair of nephridia in every segment, except for the first three and last one.There are three types of nephridia : integumentary, septal and pharyngeal nephridia. The integumentary nephridia lie attached to the inner side of the body wall in all segments except the first two. The septal nephridia are attached to both sides of the septa behind the 15th segment. The pharyngeal nephridia are attached to 4th, 5th and 6th segment. The nitrogenous wastes are removed by the rhythmic beating of the cilia of the nephridiostomes. The excretory wastes are then finally discharged into the gut.
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.
What is the function of the nephridia?
They remove metabolic wastes from an animal's body.
What is the function of a nephridia on a earthworm?
The function of an earthworm's nephridium is to excrete wastes from the earthworm's body.
