A muscular, elastic sac-like portion of the digestive tract that grinds and churns swallowed food or Bolus.

A gland that secretes bicarbonate to neutralize acid chyme that enters the small intestine.

This circular muscles regulates the flow of partially digested food into the small intestine.

The part of the GIT which is the main site of digestion of food and absorption of nutrients.

The semiliquid, partially digested food that travels through the intestinal tract is called:

The muscular contractions that move food through the GI tract are called:

The main function of bile is to:

The pancreas neutralizes acidic chyme in the small intestine by secreting:

Which nutrient passes through the GI tract mostly undigested and unabsorbed?

Absorption occurs primarily in the:

Gastrin, secretin, and cholecystokinin are examples of:

These GIT hormones stimulates pancreas to release sodium bicarbonate to neutralize acidic chyme that enters the small intestine

the sites where nutrients are mostly absorbed:

this stimulates the release of secretin and cholecystokinin:

Last stage of digestion in which nutrients are converted to absorbable units:

The organ secretes digestive enzymes and juices into the duodenum:

Digestion of Protein in the stomach:

CHO and lipids are not digested in the stomach.

The peristalsis further reduces the size of food particles and mixes them thoroughly with the digestive enzymes.

Food in the mouth stimulates the secretion of saliva from the salivary glands.

Digestion of lipids begins in the mouth

The uptake of nutrients by the cells for transport into either the blood or the lymph:

This is an action by means of chewing or mastication thru the use of our teeth and tongue after ingesting the food:

Regulates the flow of chyme into the small intestine:

An organ that stores and concentrates the bile:

The presence of chyme in the small intestine stimulates the release of GIT hormones secretin and cholecystokinin

The masticated and chewed food mixed with the mucus-like saliva is now what we called the Chyme.

HCL is actually the main reason of the strong acidity in the stomach.

Intestinal cells also secretes enzymes that catalyzes the hydrolysis of the remaining polysaccharides and peptides.
