• The human heart is not vestigial as at present times it has its own functions in the human body.
• The human heart is an organ that pumps blood throughout the body.
• Heart pumps the blood through the vessels of the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.
• The tissues of the body need a constant supply of nutrition in order to be active which is performed by blood.
