Blood cells
Oxygen! Remember it isn't the only gas. CO2 is also removed from cells in the body.
The circulatory system, which includes the heart, blood vessels, and blood, carries food, water, and oxygen to body cells. Oxygen is carried by red blood cells, nutrients by plasma, and water is distributed throughout the body.
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.
Hormones are distributed through the body by being secreted into the bloodstream by endocrine glands, which then carry them to target tissues and organs where they exert their effects. These hormones act as chemical messengers that regulate various physiological processes and help maintain homeostasis in the body.
