  • hot-water bottle

    A container usually made of rubber, filled with hot water especially to warm a bed.Containers for warmth in bed were in use as early as the 16th century. The earliest versions contained hot coals from the dying embers of the fire, and these bed warmers were used to warm the bed before getting into it. Very soon after this, containers with hot water became used. Use of hot water bottles declined in the 20th century as homes became better heated, and recently due to the increase in use of electric blankets.

  • human hair

    used to define human remains as part of the NMSI/SMG human remains policy (from April 2007); Other terms used are 'blood' and 'human remains'

  • human heart

    a hollow muscular cone-shaped organ, lying between the lungs, with the pointed end (apex) directed downwards, forwards, and to the left. The heart is about the size of a closed fist. Its wall consists largely of cardiac muscle (myocardium), lined and surrounded by membranes (see endocardium, pericardium). It is divided by a septum into separate right and left halves, each of which is divided into an upper atrium and a lower ventricle . Deoxygenated blood from the venae cavae passes through the right atrium to the right ventricle. This contracts and pumps blood to the lungs via the pulmonary artery. The newly oxygenated blood returns to the left atrium via the pulmonary veins and passes through to the left ventricle. This forcefully contracts, pumping blood out to the body via the aorta. The direction of blood flow within the heart is controlled by valves.

  • human remains

    term created as part of the NMSI human remains policy (from April 2007); Other terms used are 'blood' and 'human hair'

  • human skin

    the outer covering of the body, consisting of an outer layer, the epidermis, and an inner layer, the dermis. Beneath the dermis is a layer of fatty tissue.

  • humours

    The fluids of the body whose balance is essential to well-being. They are blood, choler (yellow bile), phlegm, and melancholy (black bile). The system of the humours was closely related to the theory of the elements by the Ancient Greeks (especially Hippocrates), who were the first society to widely embrace the theory and apply it to medical practice. In Ancient Roman culture, the theory of the humours was embraced by Galen. During the neo-classical revival in western culture, the theory of the humours was a dominant form of medical practice. Its legacy in the form of activities such as blood-letting continued in England into the eighteenth century.

    A hollow needle with a sharp point. A hypodermic needle is often used with a syringe to inject substances into the body.

  • hypodermic syringe

    A syringe is a simple piston pump consisting of a plunger that fits tightly in a tube. The plunger can be pulled and pushed along inside a cylindrical tube (the barrel), allowing the syringe to take in and expel a liquid or gas through an orifice at the open end of the tube. In modern medicine, a syringe is often fitted with a hypodermic needle to create a hypodermic syringe which is most commonly used for injecting materials directly into the bloodstream.

  • hypothermia

    A condition where the core body temperature drops below the level necessary to perform basic functions. In humans this is 35°C. Hypothermia is often caused by over exposure to cold conditions.

  • hysterectomy
