The Nervous System:
The brain has over one hundred billion neurons that travel up and down your body every time it touches something. The neurons travel travel at a speed of 800,000 km per hour and send messages to your brain about what is happening at the bottom of your body. When the neurons get to the brain there are two different parts the right side and the left side. The right side controls music and the arts while the left side controls reading and writing.If you were to damage a side of the brain that would be called ‘ Brain damage’ and you would have to have surgery and you might become paraplegic.
The Circulatory System:
The Circulatory system is very important because it pumps the blood to get to the heart. The heart is made up of two parts the left side and the right side. The left side sends the blood around the body while the right sends it back to the heart.
The Lymphatic System:
The Lymphatic system was first discovered by Thomas Bathion. Thomas first discovered the Lymphatic system in 1652 and died in 1680. The Lymphatic system contains Lymph, that is created by white blood cells that travel through the body and fight diseases. To keep your Lymphatic system healthy it is best to do things like yoga, meditation and eat healthy food.
The Muscular System:
The body is made up with over 650 muscles. Skeletal muscles work in pairs called Triceps and Biceps. Triceps and Biceps loosen and tighten the muscles in your body so you can move. The biggest muscle is called the pectoialis muscle. The Pectoialis muscle sits on the chest for men and for woman it is placed under the breast.
