Question

A bolus is
A. A mass of crushed food moistened with saliva
B. The semisolid material resulting from partial digestion in the stomach
C. The milky emulsified fat absorbed from small intestine
D. Indigestible materials that help in movement and absorption of food

Answer 1

A bolus is a mass of food that has been gnawed at the purpose of gulping Under normal conditions, the bolus is swallowed, and moves down the esophagus to the stomach for further digestion.

Complete answer:
Bolus, the food that has been bitten and blended in the mouth with saliva. Biting assists with lessening food particles to a size promptly gulped; saliva includes digestive enzymes, water, and bodily fluid that help artificially to decrease food particles, hydrate them for taste, and grease up them for simple gulping. The term bolus applies to this blend of food and arrangements until they are passed into the stomach. When the bolus arrives at the stomach, blends in with gastric juices, and gets diminished in size, the food mass is known as chyme.
A bolus can make forward and side to side movement. Process of forward movement is known as peristalsis. Forward movement took place along the length of the tube. Side to side movement of the bolus causes contraction in muscles.
So, the correct answer is option A.

Additional information : A relatively large dose of medications are administered into the vein in a short period usually 1 to 30 minutes. The IV bolus is not used for patients who have decreased cardiac output or systemic edema. The IV bolus can be used when quick administration is severely needed.

Note:- Under typical conditions, the bolus at that point goes down the throat to the stomach for digestion. Bolus has a similar tone as the food that has been bitten by the individual and is not the same as chyme. The bolus is a moved up ball-like structure framed when the creature is going to swallow. Its pH is basic in view of the presence of saliva.
