Microcosm cell

An adult human body consists of about 50 trillion cells. Each individual cell is a small universe. The steering center of a cell is the cell nucleus. It controls cell activity and carefully stores the genetic material.

Many other cell components - such as mitochondria, ribosomes, centrioles or lysosomes - perform important tasks. Human cells join forces to form functional units and thereby form different tissue structures such as skin, bones, organs, muscles and connective tissue. Cells are also found in liquid body components such as bone marrow, lymph and blood. Each cell knows its exact determination. A red blood cell would therefore never come up with the idea of becoming a heart muscle cell. Even though the functional areas in the human body are clearly separated from each other, they still work together as a well-established team.

Estimated 50,000,000,000,000 cells form a human body
