Companion Animal Anatomy and Physiology — SEG Awards Occupational Qualification Animal Care & Veterinary Revision
This element provides foundational knowledge of companion animal body systems, including cardiovascular, lymphatic, digestive, urinary, respiratory, skelet
Topic Synopsis
This element provides foundational knowledge of companion animal body systems, including cardiovascular, lymphatic, digestive, urinary, respiratory, skeletal, muscular, integumentary systems, and cellular/tissue structure. It emphasises the relationship between anatomical structures and physiological functions essential for monitoring health and providing nursing care. Practical application includes recognising normal parameters, understanding clinical signs of dysfunction, and supporting veterinary procedures.
Key Concepts & Core Principles
- Safe animal handling and restraint techniques for dogs, cats, rabbits, and small mammals, including the use of muzzles, towels, and cat bags to minimise stress and injury.
- Basic anatomy and physiology: understanding the major body systems (e.g., skeletal, digestive, respiratory) and their functions to recognise abnormalities.
- Infection control principles: aseptic technique, cleaning and disinfection protocols, and the importance of hand hygiene to prevent cross-contamination.
- Monitoring vital signs: how to measure temperature, pulse, respiration, and capillary refill time, and recognise normal ranges for common species.
- Assisting with nursing procedures: preparing equipment, restraining animals for injections or bandaging, and providing post-operative care.
Exam Tips & Revision Strategies
- Use anatomical models and interactive diagrams during revision; in assessments, always link structure to function to demonstrate full understanding.
- For coursework evidence, include clear, annotated diagrams and photographs to support written explanations, ensuring labels are precise and legible.
- When describing physiological processes, use step-by-step sequences (e.g. peristalsis in digestion) to avoid missing key stages the assessor will expect.
- Pay special attention to comparative anatomy between dogs and cats where differences exist (e.g. dental formulas, number of vertebrae) as these are common assessment discriminations.
Common Misconceptions & Mistakes to Avoid
- Confusing the roles of arteries and veins, often assuming all arteries carry oxygenated blood (pulmonary artery is an exception).
- Misidentifying the positions of abdominal organs, such as placing the spleen on the right side or mislocating the kidneys.
- Assuming the lymphatic system is entirely separate from the circulatory system, forgetting its drainage into veins.
- Oversimplifying skin structure to a single layer without recognising the distinct functions of epidermis, dermis, and associated glands.
- Misnaming bones of the forelimb versus hindlimb (e.g. confusing the carpus with the tarsus) or mixing up muscle names.
Examiner Marking Points
- Award credit for correctly identifying major organs within the thoracic and abdominal cavities and describing their positions relative to surrounding structures.
- Award credit for accurately tracing the pathway of blood through the heart and categorising major blood vessels (e.g. aorta, vena cava) and their roles in systemic and pulmonary circulation.
- Award credit for explaining the functional link between the lymphatic system and the cardiovascular system, including the role of lymph nodes in immune surveillance.
- Award credit for describing the histological layers of the skin (epidermis, dermis, hypodermis) and correlating their structure to protective and sensory functions.
- Award credit for demonstrating the ability to label major skeletal bones (e.g. femur, humerus, scapula) and common skeletal muscles (e.g. masseter, latissimus dorsi) on diagrams and explaining their basic actions.
