Body Systems Study Guide
Test on Tuesday, February 4th
Skeletal System
-There are 206 bones in the body.
-The skeleton supports the body.
-The skeleton is made up of bones held together by cartilage.
-Bones contain calcium.
-The smallest bones are in the ear; the strongest bone in the body is the femur
(thigh bone)
Muscular System
-The muscles in our body help us do many important things like: breathe, blink,
walk, and grab things.
-There are 600 muscles in the body!
-It takes 34 muscles to frown but only 13 muscles to smile!
-The body is able to move because of muscles.
-We have voluntary muscles, which we choose to move, and involuntary
muscles, which move on their own.
Circulatory System
-The heart is a hollow muscle that has two pumps.
-The valves closing make the beating sound, as the heart allows blood to pass in
and out of the chambers.
-Blood passes through the right side of the heart, to the lungs, to the left side of
the heart, and out to the body.
Respiratory System
-Everyone has a set of lungs. They are like balloons.
-When we breathe in, our lungs fill with air.
-When we breathe out, we exhale carbon dioxide.
-Our lungs work together with our heart to carry oxygen all over our body.
-There are 4 organs, which work together in this system: the lungs, the nose, the
trachea, and the bronchi.
-The air first enters our body through the nose.
-The trachea is a tube that allows the air to go to the lungs.
-The bronchi are also tubes that branch out in the lungs.
The Digestive System
-Your teeth grind up food into small pieces to be digested by the stomach.
-The tongue helps us swallow food, and then the food goes down the esophagus
to the stomach.
-The stomach is a muscle, which mixes up food. It is like a holding tank for
food.
-The stomach turns the particles of food into liquid.
-In the intestines, some of the liquid is absorbed into the body to be used for fuel.
-The rest continues through the intestines as waste.
Nervous System
-The human brain is a complex organ that allows us to think, move, feel, see,
hear, taste, and smell.
-It controls our body, receives information, analyzes information, and stores
information (our memories).
-The brain produces electrical signals to communicate to the body through
nerves.
-The adult human brain weighs 3 pounds.
-The brain is connected to the spinal cord, which runs from the neck to the hip
area.
-The spinal cord carries nerve messages between the brain and the body.
-The cranium (the top of the skull) surrounds and protects the brain.
-The spinal cord is surrounded by vertebrae (hollow spinal bones).
