The circulatory system

  1. 1. The Circulatory System
  2. 2. <ul><li>Blood travels throughout your body. Blood is able to reach every part of your body through the vessels . The way in which blood travels through the blood vessels is called circulation . </li></ul>
  3. 3. Functions of the Circulatory System <ul><li>1 . Bring oxygen and nutrients to all the cells in the body. </li></ul><ul><li>2. Protects the body from disease . </li></ul><ul><li>3. Carry waste from all the cells in the body. </li></ul>
  4. 4. 3 Parts of the Circulatory System <ul><li>1. Blood </li></ul><ul><li>2. Blood Vessels </li></ul><ul><li>3. Heart </li></ul>
  5. 5. Blood <ul><li>Blood is made up of cells and fluid called plasma . </li></ul><ul><ul><li>1. red blood cells – carry oxygen </li></ul></ul><ul><ul><li>2. white blood cells – fight disease </li></ul></ul><ul><ul><li>3. platelets – help to clot blood (stop bleeding) </li></ul></ul>
  6. 6. Blood Vessels <ul><li>Blood vessels are the tubes in which the blood travels through the body . Very small blood vessels are called capillaries . Capillaries connect the two type of blood vessels called the arteries and the veins . </li></ul>
  7. 7. Two Types of Blood Vessels <ul><li>1. arteries – carry blood away from the heart. </li></ul><ul><li>2. veins – carry blood back from the lungs and the body cells. </li></ul><ul><li>* A pulse is the beat that can be felt at the wrist and other places on the body. It occurs when blood flows through the vessels when the heart beats . </li></ul>
  8. 8. The Heart <ul><li>The heart is the primary source of the circulatory system. </li></ul><ul><li>When this powerful, muscular organ contracts, or tightens, it pumps blood to the different parts of the body. </li></ul>
  9. 9. Heart continued.. <ul><li>Nerves connect the brain to the heart. </li></ul><ul><li>The brain tell the heart how to work. </li></ul>
  10. 10. Parts of the Heart <ul><li>2 upper chambers called the atriums </li></ul><ul><li>2 lower chambers called the ventricales </li></ul><ul><li>Vena cava is the big vein to the heart from the different parts of the body </li></ul><ul><li>Aorta large artery to the body from the heart. </li></ul>
  11. 11. Flow of Blood in the Heart <ul><li>1. Vena cava (oxygen poor blood) </li></ul><ul><li>2. Right atrium (oxygen poor blood) </li></ul><ul><li>3. Right ventricle (oxygen poor blood) </li></ul><ul><li>4. Lungs (oxygen rich blood) </li></ul><ul><li>5. Left atrium (oxygen rich blood) </li></ul><ul><li>6. Left ventricle (oxygen rich blood) </li></ul><ul><li>7. Aorta (oxygen rich blood) </li></ul>
  12. 12. Continued… <ul><li>The heart is divided into 2 sides or pumps. </li></ul><ul><li>Oxygen poor blood enters the right side of the heart through the body’s veins and is pumped into the lungs . </li></ul>
  13. 13. Continued… <ul><li>In the lungs , the blood becomes rich with oxygen and reenters the heart through its left side from which it is pumped back into the body. </li></ul><ul><li>The left side of the heart is stronger and bigger because it must pump blood through the entire body. </li></ul><ul><li>It takes about 5 seconds for the heart to circulate blood through the body. </li></ul>
