The Higher Human Biology syllabus consists of 4 mandatory units which are:-

Human Cells (40 hours)

division and differentiation in human cells; structure and replication of DNA; gene expression; genes and proteins in health and disease; human genomics; metabolic pathways; cellular respiration; energy systems in muscle cells.

Physiology and Health (40 hours)

the structure and function of reproductive organs and gametes and their role in fertilisation; hormonal control of reproduction; the biology of controlling fertility; ante- and postnatal screening; the structure and function of arteries, capillaries and veins; the structure and function of the heart; pathology of cardio vascular disease (CVD); blood glucose levels and obesity linked to cardiovascular disease and diabetes.

Neurobiology and Communication (20 hours)

divisions of the nervous system and parts of the brain; perception and memory as storage, retention and retrieval of information; the cells of the nervous system and neurotransmitters at synapses; communication and social behaviour.

Learners will research issues, apply scientific skills and communicate information related to their findings, which will develop skills of scientific literacy.

Immunology and Public Health (20 hours)

non-specific defences; specific cellular defences; the transmission and control of infectious diseases; active immunisation and vaccination and the evasion of specific immune responses by pathogens.

Internal Assessment – assessed by the class teacher

To pass a unit each pupil must achieve 3 outcomes:

Outcome 1       – Planning, carrying out and reporting on an experiment / practical investigation

Outcome 2.1     – Assessment of knowledge from each key area of the unit

Outcome 2.2    – Assessment of problem solving skills

Outcome 1 and outcome 2.2 are transferable between units and so only need to achieved once. Outcome 2.1 must be achieved for each unit.

If an outcome is not achieved pupils will be offered support and an opportunity for reassessment.

External Assessment – assessed by the SQA

The course assessment is made up of two components:

Component 1 – Question Paper (Exam) 100 marks

Component 2 – Assignment 20 marks
