Explain how instructions in DNA lead to cell differentiation and result in cells specialized to perform specific functions in multicellular organisms.
Nervous System
Our nervous systems allow us to observe and react to everything that is going on around us. The cell in this system of out body send directions to our muscles, organs, and brain. Our nervous system allows us to function daily.
Circulatory System
The circulatory system is responsible for many things in our bodies including, respiration, nutrition, waste removal, immunity, cellular communication, and thermoregualtion. The cells within the blood are responsible for making each of these possible.

Muscular System
The muscular system is responsible for human body movement. When they nerves send signals to the muscles, they react. Muscles are found all over the body including the heart, digestive organs, and blood vessels.

Cardiac Muscle

Skeletal Muscle

Skelatory System
Our skeletal system cells provide structure for our bodies. Made up of 206 cells, the skeletal system provides us five things.
- Shape
- Support
- Movement
- Protection
- Blood Cell Production & Storage
Reproductive System
The reproductive system is comprised of two parts. The female egg or ovary and the male sperm.

How Are These Cells Created Different?
Cells are specialized for each of the above functions through differentiation. Through this process, different traits in each cell's DNA are activated according to what function the cell is needed to serve.
