The human body is made up of about 60 trillion cells, and each cell has its own unique characteristics and functions. The brain, which weighs about three pounds, contains billions of neurons that work together to process information and control the body's movements. The heart, which pumps blood throughout the body, beats around 100,000 times per day. The skin, which is the largest organ in the body, protects us from external threats and regulates our body temperature.
