Planaria are flatworms that live in fresh water. Their excretory system consists of two tubules connected to a highly-branched duct system that leads to pores located all along the sides of the body. The filtrate is secreted through these pores.

What is the excretory system of a flatworm?
Flatworms have an excretory system with a network of tubules throughout the body that open to the environment and nearby flame cells, whose cilia beat to direct waste fluids concentrated in the tubules out of the body. The system is responsible for regulation of dissolved salts and excretion of nitrogenous wastes.
What are the types of excretory system?
The types are: 1. Kidney 2. Ureters 3. Urinary bladder 4.
What is Protonephridial system in planaria?
Summary. Distal to the flame cells, the protonephridial tubules of fresh-water planarians are circumferentially composed of at least two cells attached by septate junctions; and may be divided, on the basis of morphological criteria, into three longitudinal regions.
What is the excretory system called?
Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs. The kidneys filter blood and form urine. They are part of the urinary system, which also includes the ureters, bladder, and urethra.
In which organism flame cells form the excretory system?
Flame cells are excretory structures in flatworms.
Are roundworms Monoecious or dioecious?
The majority of nematodes are dioecious ; that is, the sexes are separate. Some species, however, are hermaphroditic, having both male and female reproductive organs.
What is the excretory system function?
The function of the excretory system to remove wastes from the body. These wastes include water, CO2, nitrogen, salts, and heat. Metabolism: The process of the body coverting food into energy. As a result of metabolism, there are waste products.
What is the excretory system made up of?
Body parts that make up the excretory system: liver, lungs, skin, kidneys, ureters, urinary bladder, urethra.
What is the excretory product of Planaria?
Planaria are flatworms that live in fresh water. Their excretory system consists of two tubules connected to a highly-branched duct system that leads to pores located all along the sides of the body. The filtrate is secreted through these pores.
What is excretory and Osmoregulatory structure in platyhelminthes?
Platyhelminthesflatworms. ... Excretion and osmoregulation by flatworms is controlled by "flame cells" located in protonephridia (these are absent in some forms). Flatworms lack a respiratory or circulatory system; these functions take place by absorption through the body wall.
What body systems are involved in excretion of wastes?
Organs of excretion include the skin, liver, large intestine, lungs, and kidneys. All of them excrete wastes, and together they make up the excretory system . The skin plays a role in excretion through the production of sweat by sweat glands.
Which are structures of the excretory system select four options?
The kidneys, ureters, bladder, and urethra are the primary structures of the urinary system. They filter blood and remove waste from the body in the form of urine.
