During digestion of triglycerides, fatty acids enter the intestinal mucosa by diffusion; then, they are
resynthesized into triglycerides. Which of the following statements correctly describes what happens
next?
A. The triglycerides are secreted back into the lumen of the small intestine and then chemically digested
into their subunits of fatty acids and glycerol
B. The triglycerides are secreted into the interstitial fluid, where they then diffuse into the capillaries.
c. The triglycerides are coated with proteins and then secreted into the interstitial fluid, where they
diffuse into intestinal lacteals.
D. The triglycerides are absorbed directly from the intestinal cell into a capillary. - CORRECT
ANSWER✅✅C. The triglycerides are coated with proteins and then secreted into the interstitial fluid,
where they diffuse into intestinal lacteals.

The epithelium lining the stomach, small intestine, and most of the large intestine is simple columnar;
the epithelium in the oral cavity, esophagus, and pharynx is stratified squamous. Are these two
statements true or false?
Both statements are true.
The first statement is false; the second is true.

liver - CORRECT ANSWER✅✅spleen
An ulcerated stomach lining often repairs itself once the source of inflammation has been eliminated.
How is this possible?
The parasympathetic innervation of the stomach wall stimulates constant repair and renewal.
The mucosa consists of a particularly vascular epithelium that facilitates efficient repair and renewal.
The tissue lining the stomach is an epithelium and thus is capable of repair and renewal.
