The human body is a complex and intricate machine that is capable of incredible feats of strength and agility. It is made up of over 60 trillion cells, each one working together to keep us alive and functioning properly. The heart pumps blood throughout the entire system, delivering oxygen and nutrients to every part of the body. The brain, located in the head, acts as the central control unit, sending signals to the rest of the body through a complex network of nerves.
