The human body is remarkably complicated, and takes years of study to begin to understand how it all works. Indeed there are many functions within the body that we still do not fully understand.

However, at its most basic the human body is a collection of cells, the microscopic unit of living organisms. Humans are composed of many different types of cells, from skin cells that cover the exterior of your body, to muscle cells that expand and contract to help move your body, and brain cells that help control and coordinate many of the functions of the human body. These cells are specialized to their tasks, while also being able to work together with other cells to form what we call tissues.

Tissues are collections of similar cells that carry out a single function, such as bone tissue which provides structural support for the human body, and many tissues further organize into organs. You should be familiar with many different organs within the human body, such as the brain, the stomach, the lungs, and heart, and be familiar with some of their functions.

The human body works by coordinating the functions of all these organs so that we can carry out all the tasks we need to in a day, such as eating, sleeping, working, playing, and thinking.

Essentially by relying on highly specialized microscopic cells, having them coordinate with other cell types and building up more complex tissues and organs that can carry out complicated tasks, the human body is able to accomplish all of the remarkable feats we carry out every day.
