Transportation in Animals and Plants

• Circulatory System

  • Blood
    • Plasma (Liquid part)
    • Red Blood Cells (RBC) (Contains hemoglobin, carries oxygen)
    • White Blood Cells (WBC) (Fights germs and diseases)
    • Platelets (Helps in blood clotting)
  • Blood Vessels
    • Arteries
      • Carry oxygen-rich blood from heart
      • Thick, elastic walls
    • Veins
      • Carry carbon dioxide-rich blood to heart
      • Thin walls with valves
    • Capillaries
      • Extremely thin vessels
      • Connect arteries and veins
  • Heart
    • Pumping organ
    • Four chambers (Atria and Ventricles)
    • Heartbeat (Rhythmical contraction and relaxation)
    • Pulse (Throb resulting from blood flow)

• Excretion in Animals

  • Excretory System (Removal of waste products)
  • Humans
    • Kidneys (Filter blood, produce urine)
    • Ureters (Tubes connecting kidneys to bladder)
    • Urinary Bladder (Stores urine)
    • Urethra (Opening for urine release)
  • Other Organisms
    • Sweat (Removes water and salts)
    • Uric Acid (Excreted by birds, insects, lizards)
    • Ammonia (Excreted by aquatic animals like fish)

• Transportation in Plants

  • Water and Minerals Transport
    • Absorbed by roots via root hairs
    • Xylem (Vascular tissue for water transport)
    • Transpiration (Evaporation of water creating a suction pull)
  • Food Transport
    • Prepared by leaves via photosynthesis
    • Phloem (Vascular tissue for food transport)
