Higher Human Biology

The Higher Human Biology qualification develops learners’ interest in and enthusiasm for human biology in a range of contexts. Learners acquire a deeper understanding of cellular processes, physiological mechanisms, communication between organisms, and the biology of populations as they apply to the human species.

The course content includes the following areas of human biology:

Human cells

The key areas covered are:  division and differentiation in human cells  structure and replication of DNA  gene expression  mutations  human genomics  metabolic pathways  cellular respiration  energy systems in muscle cells

Physiology and health

The key areas covered are:  gamete production and fertilisation  hormonal control of reproduction  the biology of controlling fertility  antenatal and postnatal screening  the structure and function of arteries, capillaries and veins  the structure and function of the heart  pathology of cardiovascular disease (CVD)  blood glucose levels and obesity

Neurobiology and immunology

The key areas covered are:  divisions of the nervous system and neural pathways  the cerebral cortex  memory  the cells of the nervous system and neurotransmitters at synapses  non-specific body defences  specific cellular defences against pathogens  immunisation  clinical trials of vaccines and drugs
