What to Focus On

  • Heart – pumps blood throughout the body.
  • Blood – transports oxygen, nutrients, and waste.
  • Blood vessels – arteries, veins, and capillaries carry blood.

  • Plasma is 90% water and carries dissolved substances.
  • RBCs carry oxygen using haemoglobin.
  • WBCs fight infections and provide immunity.

  • Transports oxygen and carbon dioxide.
  • Carries nutrients and waste products.
  • Regulates body temperature and water balance.

Common Mistakes to Avoid

All arteries carry oxygen-rich blood and all veins carry oxygen-poor blood.

The right side of the heart sends blood to the body, and the left side sends blood to the lungs.

Red blood cells have a nucleus, just like other cells.
