Welcome to Human Biology

In this section of Biology we cover the major systems of the human body from digestive to circulatory, including...

  • effects on the body of certain hormones
  • how water content is regulated.
  • CellsTypical structure of animal cell (cytoplasm, nucleus, membrane) and specializations.
    CirculationMakeup of blood, the heart structure and circulation, blood vessels and capillaries.
    DigestionDigestive system, peristalsis, different enzymes, villi in small intestine.
    HormonesGlands' location; insulin in diabetes; Oestrogen and Testosterone in puberty; and adrenaline.
    HomeostasisRegulation of temperature and water control (nephron, glomeruli, ADH etc).
