Brain: Organ which thinks (It rules all that happens in our body)

Veins: small tubes whereby blood flows.
Heart: Organ which pumps the blood in our body
Breast (tits): female organs which feed newborn babies.
Lungs: Organs which provide oxygen to our body.
Liver: Organ which filters / shynthesizes chemical substances in our organism.
Kidneys: Organs which filter our blood when it's dirty.
