The body cavity in a starfish contains the circulatory system and the haemal system. The body cavity also helps starfish by distributing oxygen that has been distributed throughout the body, through the body.
Their skin is covered with bumpy gills.
The coelomic cavity in a starfish functions primarily for circulation of nutrients, oxygen, and waste products throughout the body. It also houses the water vascular system, which helps in movement, feeding, and respiration by regulating water pressure in the tube feet.
The space between the skin and organs of a starfish is called the coelom. This fluid-filled cavity serves as a hydrostatic skeleton, providing support and allowing for movement. It also facilitates the distribution of nutrients and waste products throughout the starfish's body. The coelom is an essential component of the starfish's anatomy, contributing to its overall function and survival.
A starfish has radial symmetry
The brain and the spinal cavity are located in the dorsal body cavity.
Pisces or fish have true internal body cavity.
starfish have bumps and spines on their body
a starfish is missing a few body parts like fins and tails
Protists do not have a body cavity like more complex, multicellular organisms. They are unicellular or simple multicellular organisms that do not have specialized body cavities. Instead, they may have structures like vacuoles or contractile vacuoles that help with maintaining internal pressures and osmoregulation.
A cavity that houses body organs is called a body cavity. The main body cavities are the thoracic cavity, abdominal cavity, and pelvic cavity, which contain organs such as the heart, lungs, stomach, and intestines.
The abdominal cavity is not part of the dorsal cavity. It is located in the ventral cavity, along with the thoracic and pelvic cavities.
The body cavity of a frog is much larger in ratio to its body than a man's body cavity is. A frog's body cavity is also much more condensed than a man's.
