A characteristic combination of atoms (including carbon and oxygen) in an organic chemical compound, formed when a combination of one oxygen atom and one hydrogen atom (together a hydroxyl group) is removed from an acid. Where lipids are concerned, acyl groups are formed when fatty acids are linked together by a molecule of glycerol.

An uncontrolled, disordered or irregular heart beat.
Any hardening (and loss of elasticity) of arteries.

Also known as hardened or furred-up arteries, atherosclerosis commonly affects the major blood vessels, such as coronary, cerebral and peripheral arteries.
A measure of the force generated by the beating of the heart pressing blood against the walls of the arteries as it is pumped around the body. A blood pressure measurement shows the higher systolic pressure (when the heart beats) and the lower diastolic pressure (when the heart relaxes).
