  1. Muscular system By: Daniela Olalde 

  2. Every person has muscles. They help do almost everything.Some muscles like the heart work on their own. Others you  can control like the  muscles in your hand. Humans have over 600 muscles.

  3. Muscles are made up of fibers that are stretchy , like  a rubberband. Each muscle is made up  of thousands of fibers What are muscles?

  4. We have 3 different types of muscles in our body: * Cardiac Muscles * Smooth Muscles *Skeletal  Muscles what types of muscles do we have?

  5. Cardiac Muscles are muscles of the heart.when it contracts it makes the heart pump blood and move blood.This type of muscle is involuntary. Cardiac muscles 

  6. Smooth muscles are found in hollow parts of the body for example: stomach , intestine , blood vessels and the bladder and are also known as involuntary muscles. smooth muscles

  7. This type of muscle tissue help hold the skeletal frame together.In another words it connects joints and skeleton bones.Skeleton muscle make 50% of our body weight.We use them to walk  and lift. skeletal muscles

  8. Well , the brain sends signals through the Nervous System to motor neurons  on muscles telling them to contract. Nerves in our muscles recive messages  and make muscles contract. Contracting causes muscles  to pull the bones to which they attached. HOw muscles work?

  9. The funtions  of our muscles are to make movements, stabilizes bones.This help us to maintain straight and keep us sitting. Funtions of our muscles 

  10. The Skeletal System interacts with the muscular System to interact muscles. The Nervous System sends signals to make a muscle move. The Circulatatory System  brings nutrients to the muscles  and takes away wastes.The main interaction bewteen the Repitatory System and the muscular is that a large flat of muscle separates the lungs from the intestine Interactions of the muscular system
