• What are the two upper chambers called?

  The left and right atria
• What are the bottom chambers called?


  Left and right ventricles
• What does the left side of the heart pump?


  oxygenated blood
• What does the right side of the heart pump?


  Deoxygenated blood
• What is an atria?


  The two top chambers of the heart
• What is a ventricles?


  The two bottom chambers of the heart
• What is a red blood cell?


  contains haemoglobin which binds oxygen which transports it around the body
• What is a white blood cell?


  Some produce antibodies (lymphocytes) while some engulf and digest foreign material (phagocytes)
• What is platelets?

• What do arteries do?


  They carry blood away from the ventricles
• What are arterioles?

  Small blood vessels that connect arteries to capillaries.
• What are venules?


  Small blood vessels that collect deoxygenated blood from capillaries and carry it back to the veins.
• What is a vein?

  They carry blood into the heart and into the atria
• What is lymph fluid?

  Tissue fluid containing white blood cells.
• What is lymphatic vessels?


  Transport lymph fluid
• What is the site of gas exchange?


  Alveoli
• What is the pulmonary circulatory system?


  The heart, lungs and all associated blood vessels that circulate blood to and from the lung
• What is systemic circulatory system

  Blood circulation around the body
• What is the vena cava?

  large vein carrying deoxygenated blood into the right atrium
• What is the aorta?

  large aretery carrying oxygenated blood from the left ventricle
• What is ventilation?
