Circulatory System

  1. Left side of heart pumps oxygen-rich blood to arteries, which carry blood to all parts of body.
  2. Blood from arteries enter capillaries; oxygen and food move to cells and the waste gas, carbon dioxide moves into the blood, this blood enters the veins.
  3. Veins carry blood with carbon dioxide to the right side of heart the heart pumps blood to lungs.
  4. In lungs, blood picks up oxygen and gives off carbon dioxide. Blood moves from left side of heart and begins again.

Heart

1. Between heartbeats heart relaxes both atriums and fills with blood.

2. When atriums contract, blood is forced through one-way openings, so blood from right atrium flows to right ventricle. Blood from left atrium flows to left ventricle.

3.Ventricles contract blood. The blood is pumped out of the heart, the right ventricle pumps blood to lungs. Left ventricle pumps blood to the rest of the body.

 

What body parts are included & what they do!
