BIE International Diploma in Embalming - Final Theory key terms

A thick-walled blood vessel that carries blood away from the heart under pressure. In embalming, arteries are the route for injecting preservative fluid because they stay identifiable and hold sutures well.

A thin-walled vessel that returns blood toward the heart and contains valves. Embalmers use large veins, such as the jugular or femoral, mainly for drainage rather than injection.

The smallest blood vessel, linking arterioles and venules, where fluid and gases exchange with tissues. Embalming fluid passes from capillaries into surrounding tissue to preserve cells.

A major artery of the neck that supplies the head and neck. It is a common injection site in embalming because it is large, accessible and reaches the face and brain.

A large artery in the thigh that supplies the lower limb. It is often used for injection when the head and neck are inaccessible, for example after autopsy or facial trauma.

A large vein in the neck that drains blood from the head. Embalmers frequently use it for drainage during carotid injection because it lies close to the carotid artery.

The chest space enclosed by the ribs and diaphragm, containing the heart, lungs and major vessels. It is one of the cavities treated during cavity embalming with a trocar.

The stiffening of muscles after death as chemical energy is depleted and muscle fibres lock. It affects positioning, injection resistance and the timing of embalming.

The purplish staining of skin caused by blood settling in dependent vessels after death. It helps estimate time since death and influences drainage and cosmetic work.

Single-celled microorganisms that can multiply rapidly in body tissues and cause disease or decomposition. Embalming fluid is designed to kill or inhibit them, but spores may survive.

A microscopic infectious agent that can only replicate inside living cells. Many viruses are destroyed by embalming fluid, but some are resistant, so standard precautions remain essential.

A dormant, highly resistant form produced by some bacteria, such as Clostridium species. Spores survive many disinfectants and ordinary embalming, so sterilisation or sporicidal products are needed.

A microorganism present in blood that can cause disease, including hepatitis B, hepatitis C and HIV. Embalmers must assume all blood and body fluids are infectious.

The microbial breakdown of body tissues after death, producing gas, odour and discolouration. It begins in the intestines and spreads, and embalming aims to slow or stop it.

The injection of preservative fluid into the arterial system so it passes through capillaries into tissues. It is the main method of preserving and sanitising a body.

The injection of concentrated preservative fluid directly into the thoracic and abdominal cavities, usually with a trocar, after aspirating gas and liquid.

The injection of preservative fluid directly into tissue using a syringe and needle. It is used where arteries are blocked or inaccessible, or for local treatment of small areas.

The force used to push embalming fluid into the arterial system, usually measured in kilopascals or pounds per square inch. Excessive pressure can cause swelling or vessel rupture.

The volume of embalming fluid delivered per unit of time. It is adjusted together with pressure to achieve good distribution without swelling or poor drainage.

The removal of blood, fluid and gas from the body during embalming, usually through a vein. Good drainage improves fluid distribution, reduces discolouration and limits swelling.

Adding special chemicals, such as dyes, humectants or surfactants, to the main embalming fluid during injection. These modify the fluid's action on tissues.

Fluid injected before the main preservative, usually containing anticoagulants and conditioners. It clears vessels and improves drainage, especially in bodies with clots or poor circulation.

The concentration of formaldehyde gas in an embalming fluid, expressed as a percentage by weight. It indicates preservative strength and guides dilution and safety precautions.

A long, hollow metal tube with a sharp point, used to aspirate and inject the cavities of the torso. It is also used to introduce cavity fluid.

A technique using six injection sites, typically both carotids, both axillaries and both femorals, when one or two sites cannot distribute fluid adequately.

Personal protective equipment such as gloves, aprons, eye protection and masks, worn to prevent contact with blood, body fluids and chemicals. It is a key part of standard precautions.

Infection control measures applied to all bodies, regardless of known infection, including hand hygiene, PPE, safe sharps handling and safe waste disposal.

A process that reduces the number of harmful microorganisms on surfaces or equipment. It does not reliably destroy bacterial spores, so it differs from sterilisation.

A process that destroys all microorganisms, including bacterial spores, on equipment. Autoclaves are commonly used for reusable instruments that must be sterile.

The transfer of infectious organisms from one person, surface or object to another. It can occur through hands, equipment, clothing or splashes during embalming.

A puncture-resistant, clearly labelled container used to dispose of needles, blades and other sharp items safely, reducing the risk of needlestick injury.

A document setting out the standards and expected conduct for embalmers, often issued by a professional body or regulator. It guides safe, respectful and ethical practice.

Ongoing learning and training that keeps an embalmer's knowledge and skills up to date, such as courses, reading and reflective practice.

The range of tasks and responsibilities an embalmer is trained and authorised to perform. Working outside it can endanger the public and breach professional standards.

A documented record of who has handled a body or item and when, from release to burial or cremation. It protects identification and supports legal investigations.

Legal or formal permission to embalm a body, obtained from the person with the right to control disposal, or from a coroner or medical examiner where required.

Agreement to a procedure given after the person has received clear information about what will happen, its purpose and any relevant risks or alternatives.

The duty to keep personal and medical information about the deceased and family private, sharing it only when legally required or necessary for care.

A legal and ethical obligation to act reasonably and avoid causing harm to the deceased, the family, colleagues and the public.
