The heart is a pump, which moves the blood. The arteries and veins are the pipes where the blood flows.

Detailed explanation-1: -Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
Detailed explanation-2: -It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.
Detailed explanation-3: -The heart is an organ which beats continuously to act as a pump for the transport of blood, which carries other substances with it. The heart pumps the deoxygenated blood to the lungs for oxygenation and receives oxygenated blood from lungs. It pumps the oxygenated blood to different parts of the body. Q.
Detailed explanation-4: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
Detailed explanation-5: -The heart is a muscular organ that pumps blood continuously throughout the body. It is comprised of four chambers-the right and left atrium and the right and left ventricle. The four chambers of the heart work together by alternately contracting and relaxing to pump blood throughout the heart.
