This unit assumes a sound understanding of topics covered in preceding health science units. Students study the structures and functions of the body needed to oxygenate tissues. Learning how the nervous system underpins multiple functional health patterns is continued by exploring basic functions of the autonomic and sensory nervous systems and associated special senses. Students will become familiar with the structures and mechanisms involved in sexual health and functional reproduction, and the major events in prenatal development. Students will further develop their understanding of relevant pharmacology as well as their practical and problem-solving skills.
