Vessel

A vessel is a tube or channel through which fluids—such as blood, water, or air—flow within a living organism or environment. In the human body, blood vessels transport blood, delivering oxygen and nutrients to tissues and removing waste products. There are different types of blood vessels: arteries carry blood away from the heart, veins return it, and capillaries facilitate exchange with tissues. In engineering or shipping, a vessel refers to a ship designed to carry goods or passengers across water. Overall, vessels are essential pathways that enable the movement and distribution of fluids in various systems.
