Question

Platyhelminthes transport of nutrition and waste in body

Answer 1

There are approximately 20,000 species of the phylum, Platyhelminthes. Now, you might be a bit confused and must be thinking what a Flatworm is. Well, let me explain, a Flatworm is a various type worm which is a part of the Platyhelminthes phylum, and includes worms such as: parasitic tapeworms and flukes, that are composed of flat, soft, and perfectly symmetric bodies. The species that are part of this phylum range from tremendously colored creatures that are located in the ocean and swim to the parasitic flatworms that live inside of, approximately, 200 million human bodies. These Flatworm creatures are hermaphroditic, which simply means that they have both male and female reproductive organs, and that they are able to produce both sexually and asexually. Now, the creatures of the Platyhelminthes phylum do not contain a body cavity nor a circulatory system. The circulatory system is very crucial for many organisms, but the species in this phylum do no have this specific system. 

Answer 2

Answer:

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.
