oxygen blood cells and non-oxygen blood cells
Oxygen diffuses into cells. Carbon dioxide diffuses out.
Capillaries
Oxygen is able to pass into your blood through diffusion. In the lungs, oxygen moves from the alveoli in the lungs into the surrounding capillaries where it binds to hemoglobin in red blood cells for transport throughout the body.
Red blood cells carry oxygen around the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and releases it to tissues throughout the body.
Hemoglobin is part of your red blood cells. It is a protein that carries oxygen throughout the body.
Red blood cells transport oxygen throughout the body. White blood cells aid in the fight against infection.
Oxygen is transported throughout the body by red blood cells in the circulatory system. When we inhale, oxygen is absorbed into the bloodstream through the lungs and binds to hemoglobin in red blood cells. These oxygen-loaded red blood cells are then carried by the circulatory system to all tissues and organs in the body, where the oxygen is released to support cellular respiration.
Red blood cells
probably oxygen
Hemoglobin, a protein found in red blood cells, is required for carrying oxygen from the lungs to body cells in humans. Hemoglobin binds to oxygen in the lungs and releases it to tissues throughout the body.
