The body Systems

• Cardiovascular System
• Digestive System
• Nervous System
• Skeletal System
• Respiratory System

Cardiovascular System

• The four chambers of the heart are the right
  atrium, the left atrium, the right ventricle, and
  the left ventricle.
• The Four valves of the heart are the pulmonary
  valve, the tricuspid valve, the aortic valve, and
  the mitral valve.
• The top number on a blood pressure reading is the
  systolic pressure
• The bottom number on a blood pressure reading is
  the diastolic pressure.
• It takes 20 seconds for the heart to pump blood
  to every part of the body.
• The movement of blood through the heart is called
  circulation.

3
The Digestive System

• The different parts of the digestive system are
  the mouth, esophagus, stomach, liver, gall
  bladder, pancreases, large intestine, small
  intestine, rectum and the anus.
• The primary function of the digestive system is
  to break down and handle foods.
• The adult digestive system is about 30 feet long.
  
• A layer of mucus in the stomach keeps it from
  digesting its self.

4
Nervous System

• The 3 main parts of the nervous system are the
  brain, the spinal cord, and all your nerves.
• Your Nervous system controls your walking,
  talking and breathing.
• Your brain weighs about 3 pounds.
• Nerve signals travel through your body at around
  200 miles per hour.

5
Skeletal System

• Four types of fractures are complete fractures,
  greenstick fractures, single fracture, and an
  open fracture.
• The different kinds of joints are fixed joints,
  parieotemporal joints, hinge joints, and ball and
  socket joints.
• The skull protects the brain.
• The ribs protect the heart, lungs and liver.
• The longest bone in your body is the femur, and
  that is in your leg.
• A baby has 300 bones that fuse together to get
  the adult total of 206 bones.

Respiratory System

• The parts of the respiratory system are the
  lungs, the diaphragm, the bronchioles, the
  capillaries, the main stem bronchi, the alveoli,
  and the trachea.
• The diaphragm allows the lungs in inhale and
  exhale.
• The trachea brings the air to the main stem
  bronchi.
• The main stem bronchi gives the air to the
  right lung and the left lung.
• Just one of the bronchi is called bronchus.
• The bronchioles are inside of your lungs and are
  like little hairs.
• The alveoli are tinny air sacs
• The blood vessels in your lungs are called
  capillaries.
• You breath in oxygen.
• You exhale carbon dioxide.
