In veterinary medicine a bolus is a large time-release tablet that stays in the rumen of cattle, goats, and sheep. It can also refer to a dose of liquid injected subcutaneously with a hypodermic needle, such as saline solution administered either to counteract dehydration or especially to mitigate kidney failure, a common ailment in domestic cats.

Subcutaneous administration is the insertion of medications beneath the skin either by injection or infusion.. A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis.
For example, if oblique 6 MV beams are used for tangential pair, 1 cm of bolus effectively becomes 1.5 cm, i.e., "full bolus". When a full bolus is applied, bolus thickness equal to the depth of the build-up region removes the skin-sparing effect of a megavoltage x-ray beam. On the other hand, there are boluses that do not require the selection ...

When a person eats food containing carbohydrates and glucose, insulin helps regulate the body's metabolism of the food. Prandial insulin, also called mealtime or bolus insulin, is designed as a bolus dose of insulin prior to a meal to regulate the spike in blood glucose that occurs following a meal. The dose of prandial insulin may be static ...
The bolus is ready for swallowing when it is held together by saliva (largely mucus), sensed by the lingual nerve of the tongue (VII—chorda tympani and IX—lesser petrosal) (V 3). Any food that is too dry to form a bolus will not be swallowed. 3) Trough formation. A trough is then formed at the back of the tongue by the intrinsic muscles (XII).
Bolus tracking is a technique to optimize timing of the imaging. A small bolus of radio-opaque contrast media is injected into a patient via a peripheral intravenous cannula . Depending on the vessel being imaged, the volume of contrast is tracked using a region of interest (abbreviated "R.O.I.") at a certain level and then followed by the CT ...
