earthworms
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.
Why do majority of parasites have no excretory system?
Many parasites have a simple body structure and rely on their host for obtaining nutrients and eliminating waste. They have evolved to live within their host's body, adapting to the host's excretory system for waste removal. Therefore, they do not need a separate excretory system.
What is the simple squamous epithelium that lines the peritoneal cavity called?
The simple squamous epithelium that lines the peritoneal cavity is called mesothelium. It is a single layer of flat cells that help protect and cushion the organs within the peritoneal cavity.
What organs did the earliest plants have?
The earliest plants, known as bryophytes, had simple structures with no distinct organs like leaves, stems, or roots. They had a structure called a thallus which served as a basic form of a plant body to absorb nutrients and water. Over time, as plants evolved, they developed more complex structures with specialized organs.
What are the organs of the simple excretory system of earthworms called?

What are the organs of the simple excreretorysystems of earthworm's called?
The organs of the simple excretory system in earthworms are called nephridia. Each segment of the earthworm contains a pair of nephridia, which function to filter and excrete waste products from the coelomic fluid. The nephridia help maintain osmoregulation and eliminate nitrogenous waste, primarily in the form of ammonia. This efficient system allows earthworms to thrive in their moist soil habitats.
How do cells from the excretory system transform into organs?
Cells from the excretory system do not transform into organs. Organs in the excretory system, like the kidneys and bladder, develop from specialized clusters of cells called germ layers during embryonic development. These cells undergo complex processes of differentiation and organization to form functional excretory organs.
What is the excretory system of a planarian?
Planaria ,which lives in fresh water ,has two strands of branching excretory tubes that open to the outside of the body through excretory pores .The simple tubular excretory is called protonephridium,Which is a network of closed tubules without internal openings.Tubular system is spread through out the body.Located along the tubulesare bulb like Flame cells
How are earthworms more complex than tapeworms?
Tapeworms have skin, intestines and reproductive organs. They are very simple creatures unlike the earthworm. Earthworms have a brain, Aortic arches, a clitellum, segments, intestines, reproductive organs, a crop, gizzard, Dorsal nerve cord, Cuticle (skin) satae, mouth and anus.
Can a living thing be called a simple organism with organs?

What are samples of simple-many celled animals?

Is kidney connective muscle nervous or epithelial tissue?
Simple cuboidal epithelium lines the surface of small excretory ducts in various organs and glands in the body and compose some of the kidney tubules in the cortex of the kidney.
What system protects internal organs from harmful bacteria sunlight and injury.?
That system is called as integumentary system. in simple word it is called as skin.
