Which organ helps in the transportation of blood?

The heart is an organ that helps in the transportation of blood.

The heart is a muscular organ that pumps blood throughout the body via a network of blood vessels, including arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart to the body's tissues, while veins carry deoxygenated blood back to the heart. Capillaries are the smallest blood vessels and connect arteries to veins, allowing for the exchange of nutrients, gases, and waste products between the blood and the body's tissues.
