Our body obtain oxygen to our body by breathing.
Capillaries obtain oxygen for the body from the alveoli in the lungs. When we inhale, oxygen enters the alveoli and diffuses across their thin walls into the surrounding capillaries, where it binds to hemoglobin in red blood cells. This oxygen-rich blood is then transported through the circulatory system to tissues and organs throughout the body.
Hydra cells get oxygen through diffusion.
Eagles obtain oxygen through breathing, just like other animals. They use their respiratory system to take in oxygen from the air and transfer it to their bloodstream, where it is delivered to cells throughout their body.
Dogs obtain oxygen by breathing in air through their noses and mouths. Oxygen from the air enters their lungs, where it is absorbed by the red blood cells in exchange for carbon dioxide. The oxygenated blood is then pumped through their body to provide energy for their cells.
Cnidarians (Jellyfish and relatives) have a body made of non-living mesoglea (which doesn't need oxygen) surrounded by 2, 1-cell thick, layers of epithelium, which obtain oxygen directly from the water.
The respiratory system works with the body to help our body function correctly. One of the things it does is it gives our cells/blood oxygen to take to the rest of our body.the respiratory system affects the body by allowing you to obtain oxygen
Crustaceans obtain oxygen through gills.

Red blood cells obtain oxygen from the lungs where they pick up oxygen from inhaled air during the process of respiration. This oxygen is then carried by red blood cells to tissues throughout the body to support cellular functions.
Who is "they" ?
you obtain oxygen from your lungs you could breath through your nose and through your mouth
multicellular organisms obtain their oxygen through the respiratory system
