NUMBERS - HUMAN BODY

You take 23,040 breaths a day, and your heart beats 42 million times a year.

Your body is composed of an estimated 37 trillion cells spread across 200 different types.

Your skin, the body's largest organ, contains 100 billion cells, while your brain houses another 100 billion neurons, enabling you to process up to 60,000 thoughts per day.

Your eyes rely on 127 million retinal cells to perceive up to 10 million colors, while your nose uses 1,000 olfactory receptors to distinguish 50,000 different scents.

Meanwhile, your circulatory system is a vast network, consisting of 30 trillion red blood cells, 42 billion blood vessels, and around 6 liters (1.6 gallons) of blood—making up roughly 10% of your body weight.

Your body’s activity is equally astonishing. Your lungs take in about 23,040 breaths per day, and your heart beats around 115,200 times daily—totaling an incredible 42 million beats per year.

With 640 muscles, 360 joints, and 206 bones, your skeletal and muscular systems provide strength and movement.

Even your hair follicles number around 100,000, each playing a role in your body’s function. Over a lifetime, you’ll produce approximately 23,000 liters (6,075 gallons) of saliva—enough to fill two swimming pools!
