Many fish spend their lives in one place, but others prefer to see a bit more of the world. Anadromous fish are of the latter, and in this lesson...
We already hinted at the purpose of a skeletal system. Protection and support are the two big reasons that organisms have skeletal systems. In your body, the skeleton works very closely with the muscular system to help you move. Without the bones of your skeleton, you would be a blob of water-filled tissues. The bones create a framework to which your muscles and organs can connect.
Skeletal System and Muscular System. People have skeletal systems made up of over 200 bones. Actually, the exact number in adults is 206 if you were wondering. In this lesson, we'll talk about how these bones and other connective tissues are organized into a skeletal system to give the body its form and protect vital organs. We'll also talk about the muscular system and how the skeletal and muscular systems work together to allow a wide range of movements and physical capabilities in humans.
