Human Biology in Simple Words

Finally, a guide to your own body that actually makes sense.

Most health books bury readers under medical jargon, footnotes, and fad-diet advice that changes every year. Human Biology In Simple Words takes a different path. In one hundred friendly pages, Lucas Harper walks you through every major system of the body, from the cells in your toes to the neurons in your brain, using plain American English and zero fluff.

You will discover how your heart pumps five liters of blood through sixty thousand miles of vessels every day, why your gut microbiome influences your mood, what the FAST test for stroke looks like, and which fifteen daily habits prevent more chronic disease than any pill ever invented.

Inside this 100-page print-ready book, you get:

• 14 clear chapters covering cells, bones, muscles, heart, lungs, digestion, liver and kidneys, brain, immune system, hormones, skin, reproduction, sleep and mental health, and nutrition
