Hormones
Hormones are chemcial messengers released into the blood stream to be carried through out the body to target cells.
A mutation is a permanent change in the DNA sequence of a gene. metabolism is the sum of all chemical reactions carried out in an organism
The traditional approach is that human and animal hormones are produced in endocrine glands, which release them directly into blood, and the bloodstream carries them to their target cells. However, it doesn't necessarily have to be blood, it can be tissue fluid as well. (And not all organisms that have hormones have blood either. In plants for example, hormones can migrate to other cells from the site of production through the plasmodesmata that connect neighboring cells.)
The bloodstream. The way it works is that endocrine glands secrete hormones into the circulatory system. In that way they are carried throughout the body.
Osmosis. The Oxygen is breathed into the lungs and the arteries that run beside and below the lungs absorb the oxygen and carry it threwout the body.
Endocrine glands secrete chemical messengers called hormones. These chemicals are secreted directly into the bloodstream, where they are carried by the circulatory system to target tissues throughout the body.

Metabolism
The chemicals secreted by the endocrine system are known as hormones. These chemical messengers are carried by the circulatory system to their target tissues.
Hormones are chemical messenger. The hormones are carried around the body in the blood to their target organs. They can act very quickly but often their effects are slow and long lasting. : )

Iris and Hermes were both immortal messengers.
The blood in the cardiovascular system carries gases, hormones, nutrients, and wastes. Oxygen, nutrients, and certain hormones are carried to the cells; and carbon dioxide, wastes, and certain hormones are carried away from the cells. Hormones are not nutrients or wastes. They are chemical messengers that are secreted by certain cells and carried to other parts of the body where they will have an effect, which depends on the hormone.
