Flatworms and jellyfish don't have a circulatory system and in these animals, the oxygen is diffused through the cells.
Paramecium obtain oxygen through diffusion across their cell membrane. This process allows oxygen to pass from the surrounding water into the cell where it is used for cellular respiration to produce energy.
Oxygen enters the bloodstream through the process of diffusion in the lungs. When we breathe in, oxygen passes through tiny air sacs in the lungs called alveoli and diffuses into the bloodstream through the thin walls of the capillaries surrounding the alveoli. This oxygen-rich blood is then pumped to the rest of the body by the heart.
Hydra cells obtain oxygen through diffusion. Gases, including oxygen, are exchanged directly with the surrounding water through the body wall of the hydra. This process allows oxygen to enter the cells and carbon dioxide to exit.
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
Animals without blood, such as sea sponges, obtain oxygen and nutrients through diffusion. They rely on their porous body structures to allow oxygen and food particles to diffuse in and waste products to diffuse out. This process occurs through direct contact with their environment.

Hydra cells get oxygen through diffusion.
"diffusion"
By the process of diffusion
diffusion
Sea lilies obtain oxygen through a process called diffusion, where oxygen is absorbed directly from the surrounding seawater through their skin and tube feet. They do not have gills or lungs like some other marine animals.
Hydra cells obtain oxygen through diffusion. Gases, including oxygen, are exchanged directly with the surrounding water through the body wall of the hydra. This process allows oxygen to enter the cells and carbon dioxide to exit.
diffusion
Oxygen is able to go into a cell by diffusion. The oxygen molecules are small enough to go through the cell membrane with that process.
Oxygen diffuses from the tracheoles into the body cells through a process called passive diffusion. This process relies on a concentration gradient, where oxygen moves from an area of high concentration in the tracheoles to an area of low concentration in the body cells.
