Food, either particles or fish, depending on the specie, is taken into the mouth by lips, then passed down using muscular actions to complete swallowing.
The mouth is subdivided into minute pores that lead to the coelenteron by tubes. Each pore has association with an external ciliated gutter which collects minute organisms and detrital matter.
Some carnivorous cnidarians cannot digest all algae, but do take varieties of nutrients from them, like oxygen and glucose.
With moon jellies, if they take in larvae of lobsters, their 'stomachs' give a bluish hue, but if they take in 'brine shrimp' they glow orange. Also, with males of moon jellies, the gonads are around the stomachs.
By diffusion of nutrients from the digestive chamber. In some larger jellyfish there are some specialised cells in the mesoglea that transport nutrients to the outer cell wall. Colony cnidarians have connecting tunnels from the main digestive chamber
Cnidarians, such as jellyfish, use stinging cells called nematocysts for defense and capturing prey. Their locomotion is typically achieved through pulsating movements of their bell or umbrella-shaped body, allowing them to move through the water. Additionally, some cnidarians like corals may remain stationary and rely on water currents to bring food and oxygen to them.
Blackworms move food and oxygen through their bodies using a process called diffusion. Nutrients and oxygen are absorbed by the body wall of the worm directly from the environment and are distributed to the cells through the circulatory system. Waste products are also eliminated from the body through diffusion.
Most of the nutrients are soaked up by the small intestine through villi, I believe.
Polyps, which are Sessile or stationary, and Medusa which move.
Blood carries oxygen, nutrients and defenses through the entire body. If y ou do not have any blood in your body it would move as well as a broken car.

A Cnidarian is a stinging animal such as a jellyfish or a sea anenome. They have stinging cells that they use predatorially for food. There are two body scructures for cnidarians--polyps and medusas. A polyp is attached to something and does not move, and its mouth is at the top. A medusa is free-swimming, and its mouth is on the bottom.

Blood contains oxygen and essential nutrients and is delivered to all cells of the body, nourishing each cell and taking the waste products away. The mechanism by which blood moves through the body is through the pumping of the heart and through major arteries which ensures blood flow.
Nutrients from digested food move from the digestive system directly into the bloodstream. Specifically, they are absorbed through the walls of the small intestine, where they enter capillaries and are transported to the liver for processing. From the liver, these nutrients are distributed to cells throughout the body to be used for energy, growth, and repair.
Blood is pumped by the heart through arteries to various tissues and organs where oxygen and nutrients are delivered. After circulating through the body, blood returns to the heart through veins to be reoxygenated in the lungs before the cycle starts again.
