ability to resist specific types of disease

breeding from two animals that are closely related, e.g. brother and sister

loss of health and increasing weakness brought about by inbreeding over successive generations

the invasion and multiplication of micro-organisms in body tissues

the body's reaction to injury and infection characterized by pain, swelling and heat

the taking in of food

a raw or processed foodstuff used in manufacturing food

a substance that is not derived from a living organism and does not contain hydrocarbon groups

drug that increases the force of cardiac contraction

the act of taking air into the body - breathing in

tidal volume + inspiratory reserve volume

the extra volume of air taken into the lungs, above that of the normal tidal volume after a forced inspiration

structures within a radiographic cassette which fluoresce when struck by X-rays

a neuron that lies between a sensory and a motor neuron but which in itself has neither sensory nor motor functions

sensory cells that detect stimuli from within the body, for example, information pertaining to blood pressure

result of crossing two animals from different species

fluid found between the cells but not within the vascular system

fluid found inside the cells

into a muscle

injection where drugs are administered into the cerebrospinal fluid

into a vein

telescoping of part of the intestine into itself causing an obstruction

the intensity of the radiation beam is inversely proportional to the square of the distance from the source i.e. X-rays diverge increasingly, the further they travel from the tube head, and their intensity falls

a charged particle

a fluid with the same osmotic pressure as that with which it is compared (usually plasma)

has the same concentration of solutes as blood plasma; water neither enters nor leaves the cells and remains in equilibrium
