Access to Higher Education Diploma (Veterinary Science)

Develop the foundational academic writing competencies required for degree-level study and for success in every subsequent assignment across the diploma. The unit covers how to structure a coherent written response, how to develop an argument from a plan, how to present written work appropriately for different academic audiences and purposes, and how to apply the principles of academic writing — clarity, objectivity, evidence-based reasoning, and formal register — to your own practice. You produce written responses to set tasks and receive structured feedback that identifies your individual development priorities from the outset.

Build the active reading strategies and note-making techniques that efficient and independent university learners depend on. The unit introduces a range of reading methods — skimming, scanning, detailed reading, and critical reading — and develops your ability to identify the purpose, argument, and tone of academic and scientific texts, to distinguish between fact, interpretation, and opinion, to evaluate the reliability and relevance of sources, and to synthesise information from multiple sources into coherent and usable notes. All skills are applied to animal science and veterinary science texts throughout the unit.

Examine the fundamental unit of life — the cell — and develop the cellular biology knowledge that underpins all subsequent units in the diploma and the biochemistry, physiology, and pathology content of veterinary and animal science degrees. The unit covers the structure and organisation of prokaryotic and eukaryotic cells, the functions of organelles including the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus, the processes of cellular activity including protein synthesis and membrane transport, and the stages and significance of the cell cycle including mitosis and its regulation. You analyse cellular dysfunction as a framework for understanding disease.

Establish the atomic and molecular chemistry foundations that veterinary science, pharmacology, and biochemistry rely upon. The unit covers the structure of the atom — protons, neutrons, and electrons — electronic configuration, the periodic table, and the principles of ionic, covalent, metallic, and hydrogen bonding. You examine how bonding type determines the structural properties of matter, analyse intermolecular forces including van der Waals interactions and dipole–dipole interactions, and consider how these concepts apply to the behaviour of biological molecules and pharmaceutical compounds encountered in veterinary contexts.

Investigate the specialised biology of animal cells and the systems that allow animals to interact with and move through their environments. The unit examines the distinctive features of animal cells compared with plant and prokaryotic cells, the structural adaptations that support different cell functions, the mechanisms of locomotion across the animal kingdom from muscular contraction in vertebrates to ciliary and flagellar movement in invertebrates, and the anatomy and physiology of sensory organs including the eye, ear, and chemoreceptors in a range of non-human animals. These foundations are directly relevant to clinical examination techniques in veterinary practice.

Explore the genetic mechanisms that underlie inheritance, variation, and the transmission of heritable disease across animal populations. The unit covers the process and stages of mitosis — including interphase, prophase, metaphase, anaphase, and telophase — and the process and significance of meiosis in sexual reproduction and the generation of genetic diversity. You examine the principles of Mendelian inheritance, monohybrid and dihybrid crosses, codominance, sex-linkage, and the sources and consequences of genetic variation including mutation. The unit provides essential grounding for understanding selective breeding, hereditary conditions, and genetic diagnostic techniques in veterinary science.

Examine the scientific study of non-human animal behaviour and the legislative and ethical frameworks that govern animal welfare in the UK. The unit investigates the major theories and mechanisms of animal behaviour including innate and learned behaviours, classical and operant conditioning, social behaviour, territorial behaviour, and communication — covering a range of species relevant to veterinary and animal science practice. You analyse the Five Freedoms of Animal Welfare, the Animal Welfare Act 2006, and the roles of organisations such as the RSPCA, SSPCA, and RCVS in promoting and enforcing animal welfare standards. The unit develops the ethical reasoning skills that veterinary professionals apply throughout their careers.

Investigate the biochemical processes by which living organisms release energy from respiratory substrates, establishing the metabolic framework essential for understanding animal physiology and clinical biochemistry in veterinary science. The unit covers the principles of energy release and the role of ATP as the universal energy currency of the cell, the aerobic respiratory pathway in detail — glycolysis in the cytoplasm, the Krebs (citric acid) cycle in the mitochondrial matrix, and the electron transport chain and oxidative phosphorylation on the inner mitochondrial membrane — and the anaerobic respiratory pathways that operate in the absence of oxygen, including lactic acid fermentation in mammalian muscle. You calculate ATP yield from different respiratory substrates and consider the clinical significance of metabolic disruption.

Analyse the nutritional requirements of different animal species and the anatomical and physiological mechanisms by which animals obtain, process, and absorb nutrients from their food. The unit covers the major nutrient groups — carbohydrates, lipids, proteins, vitamins, and minerals — their sources, biological roles, and the consequences of deficiency or excess; the principles of balanced diets across species from monogastric carnivores to ruminant herbivores; the comparative anatomy of digestive systems including monogastric, avian, and ruminant models; the process and significance of rumination; methods for calculating energy requirements at different life stages and activity levels; and the aetiology, clinical signs, and management of common nutritional disorders including obesity, undernutrition, and metabolic bone disease in companion and farm animals.

Develop the organic chemistry literacy required to engage with pharmacology, toxicology, and the chemistry of drugs and medicines in subsequent units and in veterinary science degree programmes. The unit introduces the general principles of organic chemistry including functional groups, homologous series, structural and molecular formulae, and systematic nomenclature. You examine the chemistry of alkanes — structure, bonding, physical properties, combustion, and substitution reactions — and alkenes — structure, addition reactions, and polymerisation — and develop an understanding of arenes (aromatic hydrocarbons) and the concept of delocalised electron systems. These organic chemistry principles directly underpin the study of veterinary pharmaceuticals and biosynthetic pathways.

Examine the physiological systems and processes that regulate the bodies of non-human animals, developing the systems-level biological understanding that is fundamental to veterinary clinical practice. The unit investigates the feeding behaviours of different animal groups — herbivores, carnivores, omnivores, and specialist feeders — in the context of ecological and evolutionary pressures; the respiratory and circulatory differences between major vertebrate groups including fish, amphibians, reptiles, birds, and mammals, with particular focus on gas exchange mechanisms, cardiac structure, and blood circulation; and the reproductive processes of a range of animal species, including oviparous and viviparous reproduction, the mammalian reproductive cycle, gestation, parturition, and lactation. You apply this comparative physiology to clinical scenarios encountered in veterinary practice.

Investigate the principles of medicinal chemistry as they apply to the drugs and pharmaceutical compounds used in veterinary practice, establishing a scientific basis for understanding pharmacology at degree level. The unit covers the key definitions and classifications of medicinal chemistry including receptor theory, drug targets, agonists and antagonists, and pharmacokinetics; the significance of molecular structure and functional groups upon a drug’s mode of action, potency, and selectivity; analytical methods used for drug identification and quality control including chromatography and spectroscopy; the importance of stereoisomerism and isomeric forms in determining pharmacological activity; and the common processes involved in drug design and development from lead compound identification through to clinical trials. You analyse exemplar veterinary pharmaceuticals using these principles.

Develop the quantitative literacy and statistical reasoning skills that underpin evidence-based veterinary science and animal research. The unit covers the analysis of univariate data sets including measures of central tendency (mean, median, and mode) and measures of spread (range, interquartile range, variance, and standard deviation); the organisation and analysis of data presented in frequency tables, including construction of frequency distributions and calculation of cumulative frequencies; the analysis of grouped frequency data and the interpretation of histograms and frequency polygons; and the analysis of bivariate data using scatter diagrams, Pearson’s correlation coefficient, and simple linear regression. You apply these statistical tools to animal science and veterinary research data sets throughout the unit.

Examine the physical chemistry principles that govern chemical reactions in biological systems and pharmaceutical contexts, providing the chemical underpinning for understanding metabolism, drug stability, and physiological homeostasis. The unit covers chemical kinetics including reaction rate, rate equations, the Arrhenius equation, and the factors affecting reaction rate; thermodynamics and energetics including enthalpy changes, Hess’s law, bond enthalpies, and Gibbs free energy; chemical equilibria including the equilibrium constant, Le Chatelier’s principle, and the effects of concentration, pressure, and temperature on equilibrium position; and acid–base equilibria including the Brønsted–Lowry definition, pH, Ka and pKa values, buffers, and the biological significance of pH regulation in blood and other physiological fluids.

Explore the ecological principles that govern the relationship between animals and their environments, and the policy and legislative frameworks through which the UK manages and protects its natural ecosystems. The unit covers the structure and function of habitats and ecosystems, including abiotic and biotic factors, food webs, energy flow and trophic levels, nutrient cycling, and succession; the management of ecosystems for conservation, agriculture, and sustainable use, including the tools of environmental impact assessment, habitat management, and species conservation; and the roles of UK government bodies — including Natural England, NatureScot, and the Environment Agency — and non-governmental organisations such as the Wildlife Trusts, WWF, and RSPCA in environmental protection and wildlife conservation. The unit contextualises veterinary science within the broader ecological and conservation landscape.
