What is the Difference Between Bolus and Chyme

The main difference between bolus and chyme is that bolus is the food mashed up inside the mouth, subsequently converted into chyme, whereas chyme is the food digested inside the stomach. Furthermore, the bolus is more alkaline while the chyme is more acidic. In accession to these, bolus passes into the digest through the esophagus, while chyme enters into the little intestine .
Bolus and chyme are two states of the food ingested into the gastrointestinal tract of animals .

What is the Difference Between Bolus and Chyme - Comparison Summary

What is bolus

The bolus is the ball-like combination of food and saliva produced as a result of the chewing process inside the mouthpiece. Generally, saliva is a combination of secretions of salivary glands and serous glands, which open into the oral pit. The three main pairs of salivary glands in the mouth include the parotid glands, submandibular glands, and sublingual glands. besides, the two main types of digestive enzymes give in the saliva are amylase and lingual lipase. Basically, amylase converts the starch in the food into maltose while lipase catalyzes the hydrolysis of lipids. meanwhile, the serous fluid and mucus inside the mouth are responsible for the lubrication of food .
Difference Between Bolus and Chyme furthermore, with the assistant of tongue and tooth, this combination of food and saliva is made into a bolus, which passes into the digest through the esophagus. importantly, this ball-like nature is authoritative for facilitating accept .

What is Chyme

Chyme is the creamy paste containing a mix of partially digested food and gastric juice. Generally, gastric juice chiefly contains hydrochloric acid and sodium chloride. therefore, it is powerfully acidic with a ph between 1 to 3. basically, this acidic ph causes the denaturation of proteins in the food. furthermore, the enzymes in the gastric juice are chiefly responsible for the digestion of proteins. here, pepsinogen is the independent enzyme in the gastric juice, digesting proteins. Gastric juice besides contains gastric lipase, hydrolyzing lipids. furthermore, rennin is a gastric enzyme give in infants .
Bolus vs Chyme furthermore, churning, which occurs through the peristalsis, is the process of mechanical digestion inside the abdomen. here, waves of muscular contractions, which occur along the wall of the stomach result in the mechanical breakdown of food particles while mixing gastric juice good with food .

Similarities Between Bolus and Chyme

  • Bolus and chyme are two states of the food ingested into the gastrointestinal tract .
  • Both mix with different secretions of the gastrointestinal nerve pathway .
  • They undergo both mechanical and chemical digestion.

Difference Between Bolus and Chyme

definition

Bolus refers to a indulgent, round ball of food that has been chewed and is then swallowed to make its way to the stomach while chyme refers to the liquefy depart of what passes through the stomach and into the small intestine .

parallelism

furthermore, the bolus is the food mashed up inside the mouth, subsequently converted into chyme, while the chyme is the food digested inside the stomach .

composing

While bolus is the food shuffle with saliva, chyme is the food assorted with gastric juice .

mechanical digestion

The bolus is the leave of the chewing march of food and saliva inside the mouth while the chyme is the solution of churning the food and gastric juice inside the stomach .

ph

furthermore, the bolus is more alkaline while the chyme is more acidic .

texture

While bolus is a ball-like food, chyme is a semifinal liquefy creamy paste .

color

The color of the bolus is like to that of the food, while chyme hush has the tone of the natural color of food .

Degree of Digestion

The bolus is at the beginning of the digestion while the chyme is partially finished with digestion .

decision

In abbreviated, the bolus is the resultant role of the chewing march of a mix of food and saliva. furthermore, it is ball-like and passes into the digest through the esophagus. In contrast, chyme is the solution of the churning process of bolus and gastric juice. however, it is a creamy paste, which passes into the modest intestine. consequently, the independent difference between bolus and chyme is the type of digestion of food .
