Heart

The heart is a muscular organ in most animals, including humans, which pumps blood through the blood vessels of the circulatory system, supplying oxygen and nutrients to the body while removing carbon dioxide and other wastes.

Oxygen-Rich Blood

Blood that has been oxygenated in the lungs and is being transported to cells throughout the body.

Oxygen-Poor Blood

Blood that has given up its oxygen to nourish the body's cells and now contains a higher concentration of carbon dioxide, returning to the heart and lungs for oxygenation.

Carbon Dioxide

This is a gas without color or smell, generated from the combustion of carbon and organic materials, and through respiratory activities, which plants use in photosynthesis.
