Cardiovascular System

• Includes your heart, blood and vessels
  (Arteries Veins)
• Bring Oxygen and Nutrients to the body and
  removes waste.

4
HEART

• Made of cardiac muscle
• Right atrium
• Left atrium
• These are at the top of the heart and contract
  together
• Right ventricle
• Left ventricle
• These are at the bottom of the heart and contract
  together

5
Heart

• Valves one way and separate the atrium from
  ventricle to prevent blood backflow
• The wall separates the two sides of the heart to
  prevent OXYGENATED blood from mixing with
  deoxygenated blood.

6
Types of Circulation

• Coronary to and from the heart
• Pulmonary to and from lungs
• Systemic to and from the body

7
Blood vessels

• Artery (Oxygenated) takes blood away from heart
  (red)
• Vein (Deoxygenated) takes blood to the heart.
  (blue)
• Capillaries (one cell) microscopic vessels
  where arteries and veins meet (purple)

8
Parts of Blood

• White blood cells fights infection
• Red blood cells carry oxygen (hemoglobin)
• Platelets clot the blood
• Plasma nutrients and minerals
