what is vessel in biology

Vessel in biology usually means a tube-like structure that carries fluids in living organisms. In animals, blood vessels transport blood; in plants, xylem vessels transport water and minerals.

Quick Scoop

In animals

Blood vessels are the tubes of the circulatory system that move blood around the body. They include arteries, veins, and capillaries, and they help deliver oxygen and nutrients while carrying away waste products.

In plants

A vessel is a specialized conducting structure in xylem, especially in flowering plants. It is made of connected vessel elements that form a continuous tube for moving water and dissolved minerals upward through the plant.

Simple way to remember

• Animal vessel = carries blood.

• Plant vessel = carries water and minerals.
