Here's a breakdown of how it works:
* Blood: This is the primary transport fluid. It contains:
* Red blood cells: Carry oxygen from the lungs to the body's tissues and carbon dioxide from the tissues to the lungs.
* Plasma: The liquid part of blood that carries nutrients, hormones, and waste products.
* White blood cells: Fight infection.
* Platelets: Help with blood clotting.
* Heart: This is a powerful muscle that pumps blood throughout the body.
* Blood vessels: These are the tubes that carry blood. There are three types:
* Arteries: Carry oxygenated blood away from the heart.
* Veins: Carry deoxygenated blood back to the heart.
* Capillaries: Tiny blood vessels that connect arteries and veins. They allow for exchange of gases, nutrients, and waste products between the blood and the body's cells.
