Bolus

In biology, a bolus (from the Latin word for ball), is a ball-shaped living thing.

In medicine, a bolus is a large amount of a drug given to patients to raise the blood level before treatment.

A bolus can also refer to a ball of food after it has been chewed. It passes down the oesophagus by peristalsis.
