    • Red Blood Cells
      Erythrocytes
    • Platelets
      Thrombocytes
    • White Blood Cells

      Leukocytes
    • All 3 Blood Vessels
      1. Arteries
      2. Veins
      3. Capillaries
    • What is blood made up of?
      Plasma
      RBC&WBC
      Nutrients
      Waste Products
      Oxygen
    • What are arteries?

      Bring oxygen rich blood from heart to all body cells, thick walls, highly elastic and high pressure to pump round the body
    • Circulatory System is also known as:
      Cardiovascular System
    • Function of Circulatory System
      Allows the blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones and blood cells around the body.
    • Pulmonary Circuit 

      Carries blood to lungs to be oxygenated, goes back to heart where oxygen is taken by red blood cells
    • Systemic Circuit

      Carries oxygenated blood around body to deliver it, the returns to heart. This circuit also carries nutrients and waste
    • Pulmonary artery

      transfers deoxygenated blood away from heart to lungs
    • Pulmonary Vein

      transfers oxygenated blood from lungs to heart
    • lymphocytes 

      release antibodies and activate t-cells to kill infected cells and stimulate immune response
    • Erythrocytes 

      No nucleus to enable to carry oxygen which attaches to haemaglobin ( protein) transported to target organs/ tissues
    • plasma 

      carries substances like nutrients, sugar, salts and transports blood cells to target organs/ tissues
    • Right Atrium

      First chamber to receive deoxygenated blood returning from body
    • Tricuspid Valve 

      Prevent back flow of blood from right atrium into right ventricle
    • Right Ventricle

      Deoxygenated Blood flows into right atrium and passes through tricuspid valve and into right ventricle which pumps blood up through pulmonary valve and through pulmonary valve and through pulmonary artery to the lungs
    • Bicuspid Valve 

      Permits blood to flow one way only, from left atrium into left ventricle
    • Aorta Distributes oxygen rich blood to all parts of body
    • Pulmonary Vein

      Responsible for carrying oxygenated from lungs back to left atrium of heart
    • Left Atrium 

      Holding chamber for blood returning to the lungs and act as a pump to transport blood to other areas of heart
    • Left Ventricle 

      Thickest part of heart chambers
      Responsible for pumping oxygenated blood to tissues all over body
    • Capillaries 

      Allow exchange of material la between blood and body cells via tissue fluid
      Capillaries have thin endothelium cells of one cell thick
      Decreases distance materials have to travel to be exchanged.
      1 blood cell thick
      Capillaries become venules
    • Erythrocytes function

      Has no nucleus which enables the cell to carry oxygen
      Attached to haemoglobin to target organs/tissues
    • Leukocytes function 

      Fights diseases/ infection to support the immune system
      Ingests/ destroys pathogens
    • Platelets/ Thrombocytes 

      clumps together to form a blood clot
      Act in association with thrombin and oxygen
    • Plasma function 

      Carries substances nutrients/ sugars/ salts
      Transports blood cells to target organs / tissues
    • Veins
      Carry deoxygenated blood towards the heart
      Have valves to prevent backflow - structure not really functional
