The digestive system during infancy can be accurately described by which statement?

a. Gastrointestinal problems frequently interfere with health and growth in young infants.

b. The GI tract is completely functional for digestion at 9–12 months of age.

c. Infant stools change based on the ability of the intestinal villi to absorb nutrients.

Summary Introduction

Introduction: Food gets digested in the body and the undigested food is excreted from the body in the form of stool. An infant’s digestive tract becomes fully matured by the age of six months. Before that, since the digestive tract is not completely functional it is prone to infections. Therefore, during this period it is very important to monitor the food that the infant eats and also the color, consistency and frequency of the excreta.

Explanation

Reason for the correct answer:

Option c. is given as “Infant stools change based on the ability of the intestinal villi to absorb nutrients”

The ability of intestinal villi to absorb nutrients is reflected in the consistency and frequency of the stools passed by an infant. Therefore, it can accurately describe the digestive system during infancy.

Hence, option c. is correct.

Reasons for the incorrect answers:

Option a. is given as “Gastrointestinal problems frequently interfere with health and growth in young infants”...
