platyhelminthes
What phylum of worms has a true coelom and a complete digestive tract?
The phylum Annelida includes worms that have a true coelom and a complete digestive tract. Annelids, such as earthworms and marine bristle worms, exhibit segmentation and are known for their well-developed body cavities and digestive systems.
Which is a fluid-filled space separating an animal's digestive tract from the body wall known as?
The fluid-filled space separating an animal's digestive tract from the body wall is known as the coelom. This structure provides a space for internal organs to move freely and perform their functions without being directly attached to the body wall.
Which phylum of worms has a false coelom and a complete digestive tract?
aschelminthes
Do mollusks have a pseudocoelom?
No, mollusks have a true coelom instead of a pseudocoelom. The coelom is a part of mollusks and annelids that is a cavity within the mesoderm that is filled with fluid.
Where does the coelom originate?
The coelom originates from the mesoderm during embryonic development in animals. In protostomes, the coelom typically forms through a process called schizocoely, where the mesoderm splits to create the coelomic cavity. In deuterostomes, it forms through enterocoely, where the coelom develops from pouches that bud off the digestive tract. This fluid-filled cavity plays a crucial role in the organization and functioning of complex body structures.
What is a fluid filled space separating an animal's digestive tract from the body wall known as?
The space is called the coelum, and provides cushioning of the digestive system in earthworms and some other simple animals. It allows the organs to function independently of the external structures.
Which layer of the GI tract functions by secreting a lubricating fluid?
The layer of the GI tract that functions by secreting a lubricating fluid is the mucosa. The mucosa layer is responsible for producing mucus, which acts as a lubricant to facilitate the movement of food through the digestive system. The mucus also protects the digestive organs from the effects of digestive enzymes and stomach acid.
What is the last part of the digestive tract?
The anus is the last part of the digestive tract.
