The human body is comprised of several different systems. They work together to ensure that you can move, eat, and breathe. Each system has its own set of parts, each one with a different job. Learning more about some of the different human body systems means learning more about how you work and what is going on inside your own body every day.
Just like taking the trash out when it is full, the human body also has a process for getting rid of waste. While the teeth may be one of the first things that come into contact with food, they certainly aren't the last. Getting rid of waste is actually a very important part of keeping the body healthy, and that's what the excretory system does.
The urinary system gives the body another way to get rid of waste. Made up of organs including the kidneys and the bladder, the urinary system helps the body to get rid of water and other things that it the body doesn't need. If this part of the body isn't working, it could cause a buildup of waste that could make you sick.
If you are moving, your muscles are working. The muscular system uses skeletal, smooth, and cardiac muscles to take care of the body. Lots of the organs involved in the other systems are actually muscles! Whether you are breathing, running, or even digesting food, the muscular system is getting the job done.
There are lots of glands that make up the endocrine system. This system helps you grow and even has an effect on your mood and how you sleep. Many of the parts have interesting names, like the hypothalamus and the thyroid, and they all use different chemicals inside of your body to do their jobs. Without these parts, the body wouldn't be able to do lots of important things, including turning you from a kid into an adult.
